Android App Development

Android apps built for
most of the world's phones.

Kotlin and Java engineering with on-device AI, tight security, and Play Store growth built in from day one - not a checklist added after the app ships.

What we bring

Android engineering,
done properly

Kotlin & Jetpack Compose
Modern, maintainable Android codebases built with Google's current recommended toolchain - not legacy View-based code.
On-device AI
ML Kit and TensorFlow Lite for on-device inference - image recognition, text extraction, and personalization that works offline.
Security by default
Encrypted local storage, certificate pinning, and Play Integrity API checks built into every release, not added after a security review.
Performance engineering
Startup time, memory profiling, and battery-usage optimization tested across real device tiers, not just flagship phones.
Play Store growth
Store listing optimization, phased rollouts, and crash-free rate monitoring from Play Console day one.
Maintenance & upgrades
Ongoing OS-compatibility updates, dependency upgrades, and feature work after launch - not a one-and-done build.

How we work

From requirements to
Play Store listing

Step 01

Discovery

Requirements, technical scope, and a clear read on which AI features are actually worth building.

Step 02

Design

Wireframes and Material Design UI, reviewed with your team before development starts.

Step 03

Build

Sprint-based development with internal-track builds every fortnight, so you see real progress.

Step 04

Test & secure

Device-tier testing, performance profiling, and a security pass before submission.

Step 05

Launch

Play Console submission, phased rollout, and a post-launch support window.

FAQ

Common questions about
Android app development.

It depends on feature scope, whether the app needs on-device ML or backend AI, and platform depth (e.g. Wear OS, background services). We give you a scoped estimate after a discovery call - not a flat rate that ignores your actual requirements.

Senior Kotlin and Java engineers work your project start to finish - no junior handoffs after the sales call. We also bring AI integration expertise (ML Kit, TensorFlow Lite, LLM APIs) that most Android-only shops don't have in-house.

It depends on scope, design complexity, and third-party integrations (payments, maps, ML models). We'll give you a real timeline after discovery, not a marketing estimate.

Yes - Play Console setup, store listing optimization, release management, and crash monitoring are part of every engagement, not an upsell.

Yes. On-device inference with ML Kit or TensorFlow Lite, LLM-powered features via API, and recommendation engines can typically be integrated into an existing Kotlin/Java codebase without a rewrite.
