What is Android App Development?

Android App Development — explained without the jargon.

Android development is harder than people think. The platform fragmentation alone (24K+ device models, multiple Android versions still in active use, OEM customisations) creates a QA matrix most teams underestimate. We've been shipping native Android apps since the Eclipse + Java days and now exclusively build in Kotlin with Jetpack Compose. Our apps ship to the Play Store with crash-free rates north of 99.5% on day one and stay there.

Why it matters

Three things most teams get wrong about android app development.

01

Android is 70% of global users

Outside the US, Android dominates. If you're building a consumer app or expanding internationally, Android-first isn't optional.

02

Fragmentation eats teams alive

Building for 24K device models means QA cycles, edge cases and OEM bugs most iOS-first teams aren't prepared for.

03

Play Store is its own discipline

Listing, ASO, A/B-tested store assets, internal/closed/open testing tracks — none of which iOS teams have to learn.

What's included

Everything we ship under Android App Development.

01

Kotlin + Jetpack Compose

Modern declarative UI. We don't write Java or XML layouts for new projects.

02

MVVM / Clean Architecture

Repository pattern, Hilt for DI, ViewModels, Use Cases. Code that scales past the founder team.

03

Material Design 3

Adaptive theming, dynamic colour, motion system — Material Design done right.

04

Firebase / FCM / Crashlytics

Push, analytics, crash reporting, remote config, A/B testing. Fully wired from day one.

05

Offline-first architecture

Room database, sync queues, conflict resolution. Apps that work without signal — and reconcile when back online.

06

Play Store launch support

Listing assets, internal/closed/open testing, staged rollouts, ASO baseline. We launch the app, not just code it.

FAQ

Questions you were going to ask anyway.

Native Android or cross-platform?
For consumer-facing apps with complex UX, native Android (Kotlin/Compose) delivers the best performance and platform-specific features. For MVPs and feature-light apps, cross-platform (React Native, Flutter) saves 30-40% of cost. We help you decide during discovery.
How long does Android development take?
MVPs: 10-14 weeks. Production-grade apps: 4-7 months. Apps with complex integrations (KYC, payment, biometrics): 6-9 months. We give a fixed timeline after a 1-week discovery sprint.
What does an Android app cost?
MVPs start at $18K-$35K. Mid-complexity production apps land in the $45K-$90K range. Enterprise apps with complex backend, multiple feature teams and compliance (HIPAA, PCI-DSS) run $120K+.
Do you handle Play Store submission?
Yes — submission, review responses, staged rollouts, ongoing updates. We've handled 80+ Play Store launches with zero rejections in the last 18 months.
Can you build for Wear OS, Android TV, Auto?
Yes — though they're distinct platforms with their own UX patterns. We've shipped Wear OS companion apps and Android TV apps in the past.
