This is for teams shipping a Android app, whether that's a new consumer product, an enterprise app, or an existing Android codebase that needs to feel faster and more stable.

Custom Android Development Services

We build Android apps that feel genuinely native, fast, stable, and at home on the platform. Clean architecture, smooth performance, and careful data handling are what we sweat, so the app clears review, wins users over, and stays maintainable release after release.

Off-the-shelf tools and cross-platform compromises rarely deliver the performance, security, and device integration a serious Android app needs. We build native, using Kotlin and Java to draw on everything the platform offers. Material Design 3 interfaces, careful handling of Android's lifecycle, and integration with services like WorkManager, CameraX, and the Biometric APIs. The result meets platform standards and performs reliably right across the device ecosystem.

How we help

We design to platform standards, integrate deeply with Android services, and test across a real device matrix so the app feels right on every device it runs on.

Scale an Android codebase without architectural discipline and every future feature pays for it in technical debt. We design modular, testable architectures built for the long term. MVVM with Clean Architecture, dependency injection through Hilt, and module boundaries that let teams work in parallel, so the codebase actually speeds delivery up as features and teams grow.

How we help

We define module boundaries and DI up front and apply MVVM with Clean Architecture so the codebase scales with your team instead of accumulating debt.

Because Android runs on such varied hardware, a performance issue often only shows up on a particular device or OS version. We track down and fix the bottlenecks, memory, rendering, battery, network, using Android Studio Profiler, Perfetto, and custom instrumentation to pinpoint them, then optimise layouts, cut overdraw, and tune background work so the app performs consistently across the whole spectrum.

How we help

We profile against real devices, target the memory, rendering, and battery hotspots that matter, and verify each fix across the device spectrum.

An Android app handling sensitive data is exposed on several fronts, reverse engineering, insecure storage, network interception. We build defence in depth to protect user data and clear compliance: certificate pinning, key storage through the Android Keystore, ProGuard/R8 obfuscation, and tamper detection, hardening the app against the common attack vectors and leaving it ready for a security audit.

How we help

We layer certificate pinning, Keystore-backed storage, obfuscation, and tamper detection, then document controls so security audits run smoothly.

Legacy Android codebases, deprecated APIs, Java-only implementations, dated architectures, only get harder to maintain as time passes. We modernise them incrementally, without interrupting active development: Java migrated to Kotlin, deprecated APIs replaced, architecture refactored to modern patterns, and build configuration updated, all to cut the maintenance burden and unlock current platform features.

How we help

We migrate Java to Kotlin and modernise architecture in phased, low-risk steps while keeping the app shippable throughout.

Manual testing can't keep up with Android's fragmentation and fast release cadence. We build automated testing that catches problems before users do. JUnit, Espresso, and UI Automator suites for on-device testing, Robolectric for quick unit tests, and device farms to validate broad compatibility, so releases go out backed by real automated verification rather than hope.

How we help

We build layered automated test suites and configure device farms so regressions surface early across Android's fragmented device landscape overall.

Wearables and IoT come with hardware, interface, and power constraints that standard Android patterns don't handle on their own. We engineer for those constraints from day one, with platform-specific work for Wear OS, Android TV, Android Automotive, and connected devices, designing around small displays and limited input, building features like Complications and Tiles, and optimising for ambient mode and battery.

How we help

We engineer for each target's display, input, and power constraints so the app behaves correctly on Wear OS, Android TV, Automotive, and other connected hardware.

The Android toolset

The Android tooling we rely on, grouped by what it does, and chosen deliberately from experience. Pick an area to see what we reach for and why.

We build Android apps Kotlin-first, with Java interoperability for legacy codebases, languages and frameworks that bring type safety, null safety, and access to the whole Android platform.

Kotlin
Java
Jetpack Compose
Android SDK
KotlinX Coroutines
Kotlin Flow

We pick architecture libraries that enforce separation of concerns and support testability, standardising dependency management and data persistence across modules.

Hilt
Koin
Room
Retrofit
OkHttp
WorkManager

We build interfaces on Google's recommended UI toolkits and Material Design components, for consistent behaviour across Android versions and screen sizes.

Jetpack Compose
Material Design 3
