Native Android App Development
Android apps built in Kotlin and Jetpack Compose, engineered for performance and a genuinely native Material feel across the whole device range.
Android App Development
Native Kotlin and Jetpack Compose apps tuned for real device fragmentation, tested to survive Play review, and built to actually get used. WebNX Global Services has been shipping software since 2008, working with clients around the world, including the US, UK, Canada and India.
The cost of a weak Android app
Android's device diversity punishes shortcuts more than any other platform. If any of these sound familiar, native Android development is the fix.
Android spans thousands of device and chip combinations running different OS versions. Test on one phone and ship, and the rest of your users inherit every bug you missed. We build and test against real device fragmentation, not a single reference handset.
Android users notice a sluggish, battery-hungry app within minutes, and they act on it immediately. Native Kotlin, tuned properly, stays smooth and respects the battery across every device tier, from budget to flagship.
Google Play's policies on permissions, data handling and content shift constantly and get enforced strictly. We build against current policy from day one, so the app clears review and stays published.
Android users know Material Design on sight, and an app that ignores it feels foreign the moment it opens. We build on Material 3 so the app feels like it genuinely belongs on the platform.
Android's permission model and security expectations are unforgiving. We implement secure storage, scoped storage and least-privilege permissions, so the app passes review and actually protects its users.
Every Android version changes APIs and raises minimum target requirements, and Google enforces them without exception. We keep target levels current so the app stays publishable and stable release after release.
Who we work with
We have built Android apps for retail, finance, logistics and on-demand businesses. We learn your users and their devices before we build anything for them.
What we build
From a focused phone app to a multi-device build with deep Google integration, every Android app is native, tested widely and engineered to perform.
Android apps built in Kotlin and Jetpack Compose, engineered for performance and a genuinely native Material feel across the whole device range.
Interface design built to Material 3 standards, so the app looks and behaves exactly the way Android users already expect it to.
Apps that adapt cleanly across phones, tablets, foldables and every screen density, from one properly architected codebase.
Home screen widgets, app shortcuts and quick-settings tiles that put your app's core actions one tap away.
The APIs, database, authentication and push infrastructure your Android app needs, built to fit its exact requirements.
Google Pay, Maps, Firebase, ML Kit, Sign-In and the wider Google ecosystem, integrated cleanly and kept current.
Move a legacy Java codebase to modern Kotlin and Jetpack Compose, or modernize an aging app, without losing your existing users.
Profiling and tuning of startup time, memory, battery and rendering, so the app feels fast on budget hardware and flagships alike.
Testing across a real spread of Android devices and OS versions, backed by Espresso automation and Play beta tracks.
We prepare the listing, assets and metadata, handle submission, and navigate Play review and policy until the app is live.
Title, keyword, screenshot and listing optimization so the app actually gets discovered and installed on Google Play.
Target-level updates, device support, crash monitoring and new features that keep the app current and stable long after launch.
Why choose us
Anyone can build for one phone. We build native Android that works across the whole device range, clears Play policy, and stays current as Android evolves. These are the standards behind every app we ship.
Start your projectWe build native Android in modern Kotlin and Jetpack Compose, never a web view dressed up as an app. Users can feel the difference immediately.
We test across a genuinely wide spread of devices, screen sizes and OS versions, so the app works for your whole audience, not just one phone.
Apps built to Material 3 feel native from the first tap, clear review faster and tend to earn better ratings on Google Play.
We tune for budget devices and flagships alike, so the app stays fast and battery-friendly no matter what your users are holding.
Google Play policy is strict and it keeps moving. We build against the current rules so the app gets approved and stays live.
Secure and scoped storage, least-privilege permissions and correct data handling, exactly the way Android and Google expect them.
We test on actual Android devices across versions and form factors before anything ships to your users.
We hold your app to current target levels and APIs, so it keeps publishing and running well as Android moves forward.
How we work
Eight clear stages, each with something you can see and sign off on. No black box between idea and the Play Store.
We map your users, target devices and the Android features that actually matter for this app.
Material 3 UI designed and prototyped, signed off by your team before a line of Kotlin gets written.
App architecture, backend and Google services integrations planned before development starts.
Clean Kotlin and Compose built in weekly sprints, with an internal test build to try at every stage.
Real-device testing across the Android range and OS versions, backed by automated test coverage.
We prepare the Play listing and shepherd the app through review and policy until it clears.
A monitored launch paired with Play Store optimization to drive real discovery and installs.
Target-level updates, monitoring and new features added well after launch day.
What is included
The difference between an app that works everywhere and one that crashes on half of devices is everything below. Here is what comes standard with us.
Client words
Our old app ran fine on the developer phone and crashed everywhere else. They rebuilt it in Kotlin and tested it across real devices, and crash-free sessions jumped from 92% to 99.8%. Our Play rating finally recovered along with it.
They cut through Google Play's financial-app policy that had us stuck for months. The app was approved, the security review came back clean, and Google Pay integration works flawlessly. It was clear they knew the platform inside out.
The app runs smoothly on the cheap rugged devices our drivers carry in the field, which is exactly what we needed from it. Offline mode and battery life have been excellent, and every Android update has been handled before it ever reached us.
Built with proven tools
We build with current Android frameworks and tooling so your app is modern and maintainable for years.
Questions, answered
The cost depends on the app's features, design, backend and device requirements. A focused app is simpler, while complex apps with custom backends and deep integrations require more development. Every project is scoped and quoted individually.
A focused Android app typically takes ten to eighteen weeks from design to the Play Store. Larger, more complex apps run longer. You see designs early and a test build every week, so you can try the app as it comes together rather than waiting until the end.
Native Kotlin gives the best performance, the truest Android feel, and immediate access to new platform features, which makes it the right call when Android is your priority or the app is demanding. Cross-platform frameworks like React Native or Flutter are more cost-effective if you need Android and iOS together. We advise based on what actually matters for your project.
We design responsive layouts, set sensible minimum and target SDK levels, and test across a real spread of devices, screen sizes, densities and OS versions, so the app works across the Android ecosystem instead of just the phone it was built on.
Yes. We prepare your Play listing, assets and metadata, handle submission, and manage Google Play review and policy, including resolving rejections, so the app gets approved and stays published.
Yes. We integrate Google Pay, Maps, Firebase, ML Kit, Google Sign-In, push notifications and the wider Google ecosystem, wherever your app actually needs them.
Both. We provide Android UI/UX design following Material Design 3, from wireframes through to a polished, prototyped interface, or we build from designs you already have.
Yes. We build the APIs, database, authentication and push infrastructure your app needs, or integrate cleanly with a backend and services you already run.
Yes. We take over existing apps, migrate legacy Java to Kotlin, modernize to Jetpack Compose, and add new features, all while preserving your current users and ratings.
Yes, if you want it to. We build adaptive layouts that work well across phones, tablets and foldables from a single codebase.
Google enforces minimum target SDK levels and changes APIs with every release. On a maintenance plan, we keep your app on current targets and test it against new versions, so it stays publishable and stable as Android moves forward.
Every project includes a handover and a warranty window. Most clients move onto a maintenance plan covering target-level updates, monitoring, crash fixes and new features, so the app stays current well past launch day.
