An app that breaks on half of devices
Android runs on thousands of devices with different screens, chips and OS versions. An app tested on one phone fails on the rest. We build and test for real device fragmentation.

The cost of a weak Android app
Is your Android app failing your users?
Android's device diversity punishes shortcuts. If any of these sound familiar, native Android development is the fix.
Slow, battery-draining performance
Android users notice lag and battery drain fast. Poorly built apps get uninstalled. Native Kotlin, tuned properly, runs smoothly and respects the battery on every device tier.
Play Store rejections and policy strikes
Google Play has strict and changing policies on permissions, data and content. We build to current policy so your app gets approved and stays published.
An app that ignores Material Design
Android users expect Material Design patterns. Apps that feel like an iOS port confuse them. We build with Material 3 so your app feels native to Android.
Security and permission problems
Android security and the permission model are unforgiving. We implement secure storage, scoped storage and least-privilege permissions so you pass review and protect users.
An app left behind by new Android versions
Each Android release changes APIs and target requirements. Google enforces minimum target levels. We keep your app current so it stays publishable and stable.

Why choose us
Android development done the right way
Anyone can build for one phone. We build native Android that works across the whole device range, passes Play policy and stays current, then keep it that way as Android evolves. These are the standards behind every app we ship.
Start your projectKotlin and Compose specialists
We build native Android in modern Kotlin and Jetpack Compose, not a web view wrapper. Users feel the difference.
We handle device fragmentation
We test across a real spread of devices, screen sizes and OS versions, so your app works for everyone, not just one phone.
Material Design done right
Apps built to Material 3 feel native, pass review faster and earn better ratings on Google Play.
Performance across all tiers
We tune for budget and flagship devices alike, so the app is fast and battery-friendly for your whole audience.
We navigate Play policy
Google Play policy is strict and shifting. We build to current policy so your app gets approved and stays live.
Security and permissions
Secure and scoped storage, least-privilege permissions and proper data handling, exactly as Android and Google expect.
Tested on real devices
We test on actual Android hardware across versions and form factors before anything ships.
Current with every release
We keep your app on current target levels and APIs so it stays publishable and stable as Android evolves.
How we work
Our Android app development process
Eight clear stages, each with something you can see and sign off on. No black box between idea and the Play Store.
- 01
Discovery
We map your users, target devices and the Android features that matter for your app.
- 02
Design
Material 3 UI designed and prototyped, signed off before any Kotlin is written.
- 03
Architecture
App architecture, backend and Google services integrations planned up front.
- 04
Development
Clean Kotlin and Compose built in sprints, with internal-test builds each week.
- 05
Testing
Real-device testing across the Android range and OS versions, plus automated tests.
- 06
Submission
We prepare the listing and shepherd the app through Play review and policy.
- 07
Launch & ASO
A monitored launch with Play Store optimization to drive discovery and installs.
- 08
Support
Target-level updates, monitoring and new features after launch.

Client words
Trusted by teams that ship on Android
Our previous app worked on the developer phone and crashed on everything else. They rebuilt it in Kotlin and tested across real devices. Crash-free sessions went from 92% to 99.8% and our Play rating finally recovered.
They navigated Google Play financial-app policy that had us stuck for months. The app was approved, the security review was clean, and Google Pay integration works perfectly. They clearly knew the platform inside out.
The app runs smoothly on the cheap rugged devices our drivers use in the field, which is exactly what we needed. Offline mode and battery life are excellent. Every Android update has been handled before it hit us.

Questions, answered
Android app development FAQs
How much does it cost to build an Android app?
Most native Android app projects land between $15,000 and $100,000. A focused app sits at the lower end; an app with a custom backend, multi-device support and integrations sits higher. Every quote is itemized before work begins.
How long does Android app development take?
A focused Android app typically takes 10 to 18 weeks from design to Play Store. Larger apps run longer. You see designs early and a test build every week so you can try it as it develops.
Native Kotlin or cross-platform for Android?
Native Kotlin gives the best performance, the truest Android feel and immediate access to new platform features, ideal when Android is your priority or the app is demanding. Cross-platform (React Native or Flutter) is more cost-effective if you need Android and iOS together. We advise based on your priorities.
How do you handle Android device fragmentation?
We design responsive layouts, set sensible minimum and target SDK levels, and test on a real spread of devices, screen sizes, densities and OS versions, so the app works across the Android ecosystem, not just one phone.
Do you handle Play Store submission?
Yes. We prepare your Play listing, assets and metadata, handle submission and manage Google Play review and policy, including resolving rejections, so your app gets approved and stays published.
Can you integrate Google Pay, Maps and Firebase?
Yes. We integrate Google Pay, Maps, Firebase, ML Kit, Google Sign-In, push notifications and the wider Google ecosystem as your app requires.
Do you design the app or only build it?
Both. We provide Android UI/UX design following Material Design 3, from wireframes to a polished, prototyped interface, or we build from your existing designs.
Can you build the backend for my Android app?
Yes. We build the APIs, database, authentication and push infrastructure your app needs, or integrate with your existing backend and services.
Can you modernize my existing Android app?
Yes. We take over existing apps, migrate legacy Java to Kotlin, modernize to Jetpack Compose and add features, all while keeping your current users and ratings.
Will the app support tablets and foldables?
Yes if you want it to. We build adaptive layouts that work well across phones, tablets and foldables from one codebase.
How do you keep the app working after Android updates?
Google enforces minimum target SDK levels and changes APIs each release. On a maintenance plan we keep your app on current targets and test against new versions so it stays publishable and stable.
What happens after launch?
Every project includes a handover and warranty window. Most clients move to a maintenance plan covering target-level updates, monitoring, crash fixes and new features so the app stays current.
