Android Developers Blog: Android 16 is here
Posted by Matthew McCullough – VP of Product Management, Android Developer

Today, Android is launching a few updates across the platform! This includes the start of Android 16’s rollout with details for both developers and users, a Developer Preview for enhanced Android desktop experiences with connected displays, updates for Android users across Google apps and more, plus the June Pixel Drop. We’re also recapping all the Google I/O updates for Android developers focused on building excellent, adaptive Android apps.

Today we’re releasing Android 16 and making it available on most supported Pixel devices. Look for new devices running Android 16 in the coming months.

This also marks the availability of the source code at the Android Open Source Project (AOSP). You can examine the source code for a deeper understanding of how Android works, and our focus on compatibility means that you can leverage your app development skills in Android Studio with Jetpack Compose to create applications that thrive across the entire ecosystem.

Major and minor SDK releases

With Android 16, we’ve added the concept of a minor SDK release to allow us to iterate our APIs more quickly, reflecting the rapid pace of the innovation Android is bringing to apps and devices.

We plan to have another release in Q4 of 2025 which also will include new developer APIs. Today’s major release will be the only release in 2025 to include planned app-impacting behavior changes.
In addition to new developer APIs, the Q4 minor release will pick up feature updates, optimizations, and bug fixes.

We’ll continue to have quarterly Android releases. The Q3 update in-between the API releases is providing much of the new visual polish associated with Material Expressive, and you can get the Q3 beta today on your supported Pixel device.

Camera and media APIs to empower creators

Android 16 enhances support for professional camera users, allowing for night mode scene detection, hybrid auto exposure, and precise color temperature adjustments. It’s easier than ever to capture motion photos with new Intent actions, and we’re continuing to improve UltraHDR images, with support for HEIC encoding and new parameters from the ISO 21496-1 draft standard. Support for the Advanced Professional Video (APV) codec improves Android’s place in professional recording and post-production workflows, with perceptually lossless video quality that survives multiple decodings/re-encodings without severe visual quality degradation.

Also, Android’s photo picker can now be embedded in your view hierarchy, and users will appreciate the ability to search cloud media.

More consistent, beautiful apps

Android 16 introduces changes to improve the consistency and visual appearance of apps, laying the foundation for the upcoming Material 3 Expressive changes. Apps targeting Android 16 can no longer opt-out of going edge-to-edge, and ignores the elegantTextHeight attribute to ensure proper spacing in Arabic, Lao, Myanmar, Tamil, Gujarati, Kannada, Malayalam, Odia, Telugu or Thai.

Adaptive Android apps

With Android apps now running on a variety of devices and more windowing modes on large screens, developers should build Android apps that adapt to any screen and window size, regardless of device orientation. For apps targeting Android 16 (API level 36), Android 16 includes changes to how the system manages orientation, resizability, and aspect ratio restrictions. On displays with smallest width >= 600dp, the restrictions no longer apply and apps will fill the entire display window. You should check your apps to ensure your existing UIs scale seamlessly, working well across portrait and landscape aspect ratios. We’re providing frameworks, tools, and libraries to help.

You can test these overrides without targeting using the app compatibility framework by enabling the UNIVERSAL_RESIZABLE_BY_DEFAULT flag. Read more about changes to orientation and resizability APIs in Android 16.

Predictive back by default and more

Apps targeting Android 16 will have system animations for back-to-home, cross-task, and cross-activity by default. In addition, Android 16 extends predictive back navigation to three-button navigation, meaning that users long-pressing the back button will see a glimpse of the previous screen before navigating back.

To make it easier to get the back-to-home animation, Android 16 adds support for the onBackInvokedCallback with the new PRIORITY_SYSTEM_NAVIGATION_OBSERVER. Android 16 additionally adds the finishAndRemoveTaskCallback and moveTaskToBackCallback for custom back stack behavior with predictive back.

Consistent progress notifications

Android 16 introduces Notification.ProgressStyle, which lets you create progress-centric notifications that can denote states and milestones in a user journey using points and segments. Key use cases include rideshare, delivery, and navigation. It’s the basis for Live Updates, which will be fully realized in an upcoming Android 16 update.

Custom AGSL graphical effects

Android 16 adds RuntimeColorFilter and RuntimeXfermode, allowing you to author complex effects like Threshold, Sepia, and Hue Saturation in AGSL and apply them to draw calls.

Help to create better performing, more efficient apps and games

From APIs to help you understand app performance, to platform changes designed to increase efficiency, Android 16 is focused on making sure your apps perform well. Android 16 introduces system-triggered profiling to ProfilingManager, ensures at most one missed execution of scheduleAtFixedRate is immediately executed when the app returns to a valid lifecycle for better efficiency, introduces hasArrSupport and getSuggestedFrameRate(int) to make it easier for your apps to take advantage of adaptive display refresh rates, and introduces the getCpuHeadroom and getGpuHeadroom APIs along with CpuHeadroomParams and GpuHeadroomParams in SystemHealthManager to provide games and resource-intensive apps estimates of available GPU and CPU resources on supported devices.

JobScheduler updates

JobScheduler.getPendingJobReasons in Android 16 returns multiple reasons why a job is pending, due to both explicit constraints you set and implicit constraints set by the system. The new JobScheduler.getPendingJobReasonsHistory returns the list of the most recent pending job reason changes, allowing you to better tune the way your app works in the background.

Android 16 is making adjustments for regular and expedited job runtime quota based on which apps standby bucket the app is in, whether the job starts execution while the app is in a top state, and whether the job is executing while the app is running a Foreground Service.

To detect (and then reduce) abandoned jobs, apps should use the new STOP_REASON_TIMEOUT_ABANDONED job stop reason that the system assigns for abandoned jobs, instead of STOP_REASON_TIMEOUT.

16KB page sizes

Android 15 introduced support for 16KB page sizes to improve the performance of app launches, system boot-ups, and camera starts, while reducing battery usage. Android 16 adds a 16 KB page size compatibility mode, which, combined with new Google Play technical requirements, brings Android closer to having devices shipping with this important change. You can validate if your app needs updating using the 16KB page size checks & APK Analyzer in the latest version of Android Studio.

ART internal changes

Android 16 includes the latest updates to the Android Runtime (ART) that improve the Android Runtime’s (ART’s) performance and provide support for additional language features. These improvements are also available to over a billion devices running Android 12 (API level 31) and higher through Google Play System updates. Apps and libraries that rely on internal non-SDK ART structures may not continue to work correctly with these changes.

Privacy and security

Android 16 continues our mission to improve security and ensure user privacy. It includes Improved security against Intent redirection attacks, makes MediaStore.getVersion unique to each app, adds an API that allows apps to share Android Keystore keys, incorporates the latest version of the Privacy Sandbox on Android, introduces a new behavior during the companion device pairing flow to protect the user’s location privacy, and allows a user to easily select from and limit access to app-owned shared media in the photo picker.

Local network permission testing

Android 16 allows your app to test the upcoming local network permission feature, which will require your app to be granted NEARBY_WIFI_DEVICES permission. This change will be enforced in a future Android major release.

An Android built for everyone

Android 16 adds features such as Auracast broadcast audio with compatible LE Audio hearing aids, Accessibility changes such as extending TtsSpan with TYPE_DURATION, a new list-based API within AccessibilityNodeInfo, improved support for expandable elements using setExpandedState, RANGE_TYPE_INDETERMINATE for indeterminate ProgressBar widgets, AccessibilityNodeInfo getChecked and setChecked(int) methods that support a “partially checked” state, setSupplementalDescription so you can provide text for a ViewGroup without overriding information from its children, and setFieldRequired so apps can tell an accessibility service that input to a form field is required.

Outline text for maximum text contrast

Android 16 introduces outline text, replacing high contrast text, which draws a larger contrasting area around text to greatly improve legibility, along with new AccessibilityManager APIs to allow your apps to check or register a listener to see if this mode is enabled.

Text with enhanced contrast before and after Android 16’s new outline text accessibility feature

Get your apps, libraries, tools, and game engines ready!

If you develop an SDK, library, tool, or game engine, it’s even more important to prepare any necessary updates now to prevent your downstream app and game developers from being blocked by compatibility issues and allow them to target the latest SDK features. Please let your developers know if updates to your SDK are needed to fully support Android 16.

Testing involves installing your production app or a test app making use of your library or engine using Google Play or other means onto a device or emulator running Android 16. Work through all your app’s flows and look for functional or UI issues. Review the behavior changes to focus your testing. Each release of Android contains platform changes that improve privacy, security, and overall user experience, and these changes can affect your apps. Here are several changes to focus on that apply, even if you aren’t yet targeting Android 16:
Other changes that will be impactful once your app targets Android 16:

Get your app ready for the future:
Remember to thoroughly exercise libraries and SDKs that your app is using during your compatibility testing. You may need to update to current SDK versions or reach out to the developer for help if you encounter any issues.

Once you’ve published the Android 16-compatible version of your app, you can start the process to update your app’s targetSdkVersion. Review the behavior changes that apply when your app targets Android 16 and use the compatibility framework to help quickly detect issues.

Get started with Android 16

Your Pixel device should get Android 16 shortly if you haven’t already been on the Android Beta. If you don’t have a Pixel device, you can use the 64-bit system images with the Android Emulator in Android Studio. If you are currently on Android 16 Beta 4.1 and have not yet taken an Android 16 QPR1 beta, you can opt out of the program and you will then be offered the release version of Android 16 over the air.

For the best development experience with Android 16, we recommend that you use the latest Canary build of Android Studio Narwhal. Once you’re set up, here are some of the things you should do:

Thank you again to everyone who participated in our Android developer preview and beta program. We’re looking forward to seeing how your apps take advantage of the updates in Android 16, and have plans to bring you updates in a fast-paced release cadence going forward.

Apple Worldwide Developers Conference Day 1: WWDC Highlights

Apple announced sweeping changes to its products on Monday, the first day of its annual Worldwide Developers Conference (WWDC).

Notably, the iPhone maker confirmed rumors that it is changing how it names its software updates. Instead of using a version number, Apple will use a system with a number that represents the year after the update is released. Apple’s next update will be iOS 26, arriving in the fall for most Apple users.

The naming change applies to all Apple products. For example, the next iPad update will be named iPadOS 26, and the next MacBook update will be called macOS 26.

Related: This College Student Wanted to Help People During the LA Wildfires. She Built a Practical App in Just 1 Month — and Won Apple’s Annual Competition.

Apple announced other changes, like a new design and AI features. The company has made all of the new features available for testing starting on Monday through the Apple Developer program, with a public beta version to be released next month and a broader update rolling out this fall.

“We continue to advance each of our platforms with more ways to harness the power of Apple Intelligence, as well as a beautiful new design, our product experiences become even more seamless and enjoyable,” Apple CEO Tim Cook said during the event keynote.

Here are some interesting new capabilities Apple debuted on Monday.

1. A new design with Liquid Glass

Apple made its biggest design update ever, with a new design element called Liquid Glass. The translucent element, which Apple used to craft new buttons, switches, tab bars, and notifications across its products, looks like glass on the screen and takes on the color of its environment.

“This is our broadest software design update ever,” Alan Dye, Apple’s vice president of Human Interface Design, stated in a press release. “It combines the optical qualities of glass with a fluidity only Apple can achieve, as it transforms depending on your content or context.”

Apple has integrated Liquid Glass components into its redesign, including translucent menus that respond to a user’s perspective of the screen and a new lock screen with a Liquid Glass time.

Apple’s new Liquid Glass design applies to iOS, iPadOS, macOS, watchOS, and tvOS for a unified look.

2. Live Translation will be integrated into the iPhone

Apple is bringing Live Translation to Messages, FaceTime, and Phone to translate text and audio on the spot. The AI-powered feature is backed by Apple-built AI models that run entirely locally, so personal conversations are never uploaded to the cloud.

Live Translation means that users can talk to each other in different languages, and have the translation appear on the screen in real-time. For example, when a user receives an iMessage in another language, they can opt for that message to be translated into their preferred language. On FaceTime, a user can hear someone talking in another language while following along with translated live captions.

3. Visual intelligence gets sharper

Apple is bringing more AI capabilities to the forefront with visual intelligence. Users can tap into their iPhone cameras and use what they see to ask ChatGPT questions. They can also search Google or Etsy to find products similar to what they are looking at.

Visual intelligence also recognizes when a user is looking at a poster of an event, and can extract the data to add as an event on their calendar.

4. Workout Buddy on Apple Watch

Apple is adding an AI workout companion to the Apple Watch called Workout Buddy.

Workout Buddy considers metrics tracked by the Apple Watch, like heart rate, pace, distance, and previous workouts, and leverages this knowledge to motivate users during their workouts with verbal encouragement.

For example, when a user starts their run, Workout Buddy could say, “Great job starting your run. This is your second run this week.”

Workout Buddy will be available for workout types like indoor run and outdoor cycle.

Apple announced sweeping changes to its products on Monday, the first day of its annual Worldwide Developers Conference (WWDC).

Notably, the iPhone maker confirmed rumors that it is changing how it names its software updates. Instead of using a version number, Apple will use a system with a number that represents the year after the update is released. Apple’s next update will be iOS 26, arriving in the fall for most Apple users.

Android Developers Blog: Announcing Jetpack Navigation 3
Posted by Don Turner – Developer Relations Engineer

Navigating between screens in your app should be simple, shouldn’t it? However, building a robust, scalable, and delightful navigation experience can be a challenge. For years, the Jetpack Navigation library has been a key tool for developers, but as the Android UI landscape has evolved, particularly with the rise of Jetpack Compose, we recognized the need for a new approach.

Today, we’re excited to introduce Jetpack Navigation 3, a new navigation library built from the ground up specifically for Compose. For brevity, we’ll just call it Nav3 from now on. This library embraces the declarative programming model and Compose state as fundamental building blocks.

Why a new navigation library?

The original Jetpack Navigation library (sometimes referred to as Nav2 as it’s on major version 2) was initially announced back in 2018, before AndroidX and before Compose. While it served its original goals well, we heard from you that it had several limitations when working with modern Compose patterns.

One key limitation was that the back stack state could only be observed indirectly. This meant there could be two sources of truth, potentially leading to an inconsistent application state. Also, Nav2’s NavHost was designed to display only a single destination – the topmost one on the back stack – filling the available space. This made it difficult to implement adaptive layouts that display multiple panes of content simultaneously, such as a list-detail layout on large screens.

Figure 1. Changing from single pane to multi-pane layouts can create navigational challenges

Founding principles

Nav3 is built upon principles designed to provide greater flexibility and developer control:

You own the back stack: You, the developer, not the library, own and control the back stack. It’s a simple list which is backed by Compose state. Specifically, Nav3 expects your back stack to be SnapshotStateList<T> where T can be any type you choose. You can navigate by adding or removing items (Ts), and state changes are observed and reflected by Nav3’s UI.

Get out of your way: We heard that you don’t like a navigation library to be a black box with inaccessible internal components and state. Nav3 is designed to be open and extensible, providing you with building blocks and helpful defaults. If you want custom navigation behavior you can drop down to lower layers and create your own components and customizations.

Pick your building blocks: Instead of embedding all behavior within the library, Nav3 offers smaller components that you can combine to create more complex functionality. We’ve also provided a “recipes book” that shows how to combine components to solve common navigation challenges.

Figure 2. The Nav3 display observes changes to the developer-owned back stack.

Key features

Adaptive layouts: A flexible layout API (named Scenes) allows you to render multiple destinations in the same layout (for example, a list-detail layout on large screen devices). This makes it easy to switch between single and multi-pane layouts.

Modularity: The API design allows navigation code to be split across multiple modules. This improves build times and allows clear separation of responsibilities between feature modules.

Figure 3. Custom animations and predictive back are easy to implement, and easy to override for individual destinations.

Basic code example

To give you an idea of how Nav3 works, here’s a short code sample.

// Define the routes in your app and any arguments. data object Home data class Product(val id: String) // Create a back stack, specifying the route the app should start with. val backStack = remember { mutableStateListOf<Any>(Home) } // A NavDisplay displays your back stack. Whenever the back stack changes, the display updates. NavDisplay( backStack = backStack, // Specify what should happen when the user goes back onBack = { backStack.removeLastOrNull() }, // An entry provider converts a route into a NavEntry which contains the content for that route. entryProvider = { route -> when (route) { is Home -> NavEntry(route) { Column { Text("Welcome to Nav3") Button(onClick = { // To navigate to a new route, just add that route to the back stack backStack.add(Product("123")) }) { Text("Click to navigate") } } } is Product -> NavEntry(route) { Text("Product ${route.id} ") } else -> NavEntry(Unit) { Text("Unknown route: $route") } } } )

Get started and provide feedback

To get started, check out the developer documentation, plus the recipes repository which provides examples for:

common navigation UI, such as a navigation rail or bar

conditional navigation, such as a login flow

custom layouts using Scenes

We plan to provide code recipes, documentation and blogs for more complex use cases in future.

Nav3 is currently in alpha, which means that the API is liable to change based on feedback. If you have any issues, or would like to provide feedback, please file an issue.

Nav3 offers a flexible and powerful foundation for building modern navigation in your Compose applications. We’re really excited to see what you build with it.

What’s new in Developer Preview 2

Since the release of Developer Preview 1, we’ve been focused on making the APIs easier to use and adding new immersive Android XR features. Your feedback has helped us shape the development of the tools, SDKs, and the platform itself.

With the Jetpack XR SDK, you can now play back 180° and 360° videos, which can be stereoscopic by encoding with the MV-HEVC specification or by encoding view-frames adjacently. The MV-HEVC standard is optimized and designed for stereoscopic video, allowing your app to efficiently play back immersive videos at great quality. Apps built with Jetpack Compose for XR can use the SpatialExternalSurface composable to render media, including stereoscopic videos.

Using Jetpack Compose for XR, you can now also define layouts that adapt to different XR display configurations. For example, use a SubspaceModifier to specify the size of a Subspace as a percentage of the device’s recommended viewing size, so a panel effortlessly fills the space it’s positioned in.

Material Design for XR now supports more component overrides for TopAppBar, AlertDialog, and ListDetailPaneScaffold, helping your large-screen enabled apps that use Material Design effortlessly adapt to the new world of XR.

An app adapts to XR using Material Design for XR with the new component overrides

In ARCore for Jetpack XR, you can now track hands after requesting the appropriate permissions. Hands are a collection of 26 posed hand joints that can be used to detect hand gestures and bring a whole new level of interaction to your Android XR apps:

Hands bring a natural input method to your Android XR experience.

For more guidance on developing apps for Android XR, check out our Android XR Fundamentals codelab, the updates to our Hello Android XR sample project, and a new version of JetStream with Android XR support.

The Android XR Emulator has also received updates to stability, support for AMD GPUs, and is now fully integrated within the Android Studio UI.

The Android XR Emulator is now integrated in Android Studio

Developers using Unity have already successfully created and ported existing games and apps to Android XR. Today, you can upgrade to the Pre-Release version 2 of the Unity OpenXR: Android XR package! This update adds many performance improvements such as support for Dynamic Refresh Rate, which optimizes your app’s performance and power consumption. Shaders made with Shader Graph now support SpaceWarp, making it easier to use SpaceWarp to reduce compute load on the device. Hand meshes are now exposed with occlusion, which enables realistic hand visualization.

Check out Unity’s improved Mixed Reality template for Android XR, which now includes support for occlusion and persistent anchors.

We recently launched Android XR Samples for Unity, which demonstrate capabilities on the Android XR platform such as hand tracking, plane tracking, face tracking, and passthrough.

Google’s open-source Unity samples demonstrate platform features and show how they’re implemented

The Firebase AI Logic for Unity is now in public preview! This makes it easy for you to integrate gen AI into your apps, enabling the creation of AI-powered experiences with Gemini and Android XR. The Firebase AI Logic fully supports Gemini’s capabilities, including multimodal input and output, and bi-directional streaming for immersive conversational interfaces. Built with production readiness in mind, Firebase AI Logic is integrated with core Firebase services like App Check, Remote Config, and Cloud Storage for enhanced security, configurability, and data management. Learn more about this on the Firebase blog or go straight to the Gemini API using Vertex AI in Firebase SDK documentation to get started.

Continuing to build the future together

Our commitment to open standards continues with the glTF Interactivity specification, in collaboration with the Khronos Group. which will be supported in glTF models rendered by Jetpack XR later this year. Models using the glTF Interactivity specification are self-contained interactive assets that can have many pre-programmed behaviors, like rotating objects on a button press or changing the color of a material over time.

Android XR will be available first on Samsung’s Project Moohan, launching later this year. Soon after, our partners at XREAL will release the next Android XR device. Codenamed Project Aura, it’s a portable and tethered device that gives users access to their favorite Android apps, including those that have been built for XR. It will launch as a developer edition, specifically for you to begin creating and experimenting. The best news? With the familiar tools you use to build Android apps today, you can build for these devices too.

XREAL’s Project Aura

The Google Play Store is also getting ready for Android XR. It will list supported 2D Android apps on the Android XR Play Store when it launches later this year. If you are working on an Android XR differentiated app, you can get it ready for the big launch and be one of the first differentiated apps on the Android XR Play Store:

Android Developers Blog: Introducing Widget Quality Tiers

Posted by Ivy Knight – Senior Design Advocate

Level up your app Widgets with new quality tiers

Widgets can be a powerful tool for engaging users and increasing the visibility of your app. They can also help you to improve the user experience by providing users with a more convenient way to access your app’s content and features.

To build a great Android widget, it should be helpful, adaptive, and visually cohesive with the overall aesthetic of the device home screen.

In order to help you achieve a great widget, we are pleased to introduce Android Widget Quality Tiers!

The new Widget quality tiers are here to help guide you towards a best practice implementation of widgets, that will look great and bring your user’s value across the ecosystem of Android Phone, Tablets and Foldables.

What does this mean for widget makers?

Whether you are planning a new widget, or investing in an update to an existing widget, the Widget Quality Tiers will help you evaluate and plan for a high quality widget.

Just like Large Screen quality tiers help optimize app experiences, these Widget tiers guide you in creating great widgets across all Android devices. Now, similar tiers are being introduced for widgets to ensure they’re not just functional, but also visually appealing and user-friendly.

Widgets that meet quality tier guidelines will be discoverable under the new Widget filter in Google Play.

Consider using our Canonical Widget layouts, which are based on Jetpack Glance components, to make it easier for you to design and build a Tier 1 widget your users will love.

Let’s take a look at the Widget Quality Tiers

There are three tiers built with required system defaults and suggested guidance to create an enhanced widget experience:

Tier 1: Differentiated

Differentiated widgets go further by implementing theming and adapting to resizing.

Tier 1 widgets are exemplary widgets offering hero experiences that are personalized, and create unique and productive homescreens. These widgets meet Tier 2 standards plus enhancements for layout, color, discovery, and system coherence criteria.

For example, use the system provided corner radius, and don’t set a custom corner radius on Widgets.

Add more personalization with dynamic color and generated previews while ensuring your widgets look good across devices by not overriding system defaults.

Tier 1 widgets that, from the top left, properly crop content, fill the layout bounds, have appropriately sized headers and touch targets, and make good use of colors and contrast.

Tier 2: Quality Standard

These widgets are helpful, usable, and provide a quality experience. They meet all criteria for layout, color, discovery, and content.

Make sure your widget has appropriate touch targets.

Tier 2 widgets are functional but simple, they meet the basic criteria for a usable app. But if you want to create a truly stellar experience for your users, tier 1 criteria introduce ways to make a more personal, interactive, and coherent widget.

Tier 3: Low Quality

These widgets don’t meet the minimum quality bar and don’t provide a great user experience, meaning they are not following or missing criteria from Tier 2.

Clockwise from the top left not filling the bounds, poorly cropped content, low color contrast, mis-sized header, and small touch targets.

For example, ensure content is visible and not cropped

Build and elevate your Android widgets with Widget Quality Tiers

Dive deeper into the widget quality tiers and start building widgets that not only look great but also provide an amazing user experience! Check out the official Android documentation for detailed information and best practices.

This blog post is part of our series: Spotlight Week on Widgets, where we provide resources—blog posts, videos, sample code, and more—all designed to help you design and create widgets. You can read more in the overview of Spotlight Week: Widgets, which will be updated throughout the week.

Android Developers Blog: #WeArePlay | How Memory Lane Games helps people with dementia

Posted by Robbie McLachlan – Developer Marketing

In our latest #WeArePlay film, which celebrates the people behind apps and games, we meet Bruce – a co-founder of Memory Lane Games. His company turns cherished memories into simple, engaging quizzes for people with different types of dementia. Discover how Memory Lane Games blends nostalgia and technology to spark conversations and emotional connections.

https://www.youtube.com/watch?v=oBDJH8h7FYs

What inspired the idea behind Memory Lane Games?

The idea for Memory Lane Games came about one day at the pub when Peter was telling me how his mum, even with vascular dementia, lights up when she looks at old family photos. It got me thinking about my own mum, who treasures old photos just as much. The idea hit us – why not turn those memories into games? We wanted to help people reconnect with their past and create moments where conversations could flow naturally.

Can you tell us of a memorable moment in the journey when you realized how powerful the game was?

We knew we were onto something meaningful when a caregiver in a memory cafe told us about a man who was pretty much non-verbal but would enjoy playing. He started humming along to one of our music trivia games, then suddenly said, “Roy Orbison is a way better singer than Elvis, but Elvis had a better manager.” The caregiver was in tears—it was the first complete sentence he’d spoken in months. Moments like these remind us why we’re doing this—it’s not just about games; it’s about unlocking moments of connection and joy that dementia often takes away.

One of the key features is having errorless fun with the games, why was that so important?

We strive for frustration-free design. With our games, there are no wrong answers—just gentle prompts to trigger memories and spark conversations about topics they are interested in. It’s not about winning or losing; it’s about rekindling connections and creating moments of happiness without any pressure or frustration. Dementia can make day-to-day tasks challenging, and the last thing anyone needs is a game that highlights what they might not remember or get right. Caregivers also like being able to redirect attention back to something familiar and fun when behaviour gets more challenging.

How has Google Play helped your journey?

What’s been amazing is how Google Play has connected us with an incredibly active and engaged global community without any major marketing efforts on our part.

For instance, we got our first big traction in places like the Philippines and India—places we hadn’t specifically targeted. Yet here we are, with thousands of downloads in more than 100 countries. That reach wouldn’t have been possible without Google Play.

What is next for Memory Lane Games?

We’re really excited about how we can use AI to take Memory Lane Games to the next level. Our goal is to use generative AI, like Google’s Gemini, to create more personalized and localized game content. For example, instead of just focusing on general memories, we want to tailor the game to a specific village the player came from, or a TV show they used to watch, or even local landmarks from their family’s hometown. AI will help us offer games that are deeply personal. Plus, with the power of AI, we can create games in multiple languages, tapping into new regions like Japan, Nigeria or Mexico.
