Your Android users are on hundreds of different phones. Your app has to work on all of them.

We build Android apps in Kotlin and Jetpack Compose that run smoothly across devices and screen sizes, and stay fast on budget phones.

## Problems we solve

- The app crashes on phones we never tested: One model, one OS version, and a flood of one-star reviews.
- It drains the battery and users uninstall it: Untuned background work is quietly costing you users.
- Our Android app is always behind the iOS one: Features ship months later, if at all.
- Play Store policy changes catch us out: First a warning email, then a removed app.

## What we build

- Kotlin and Jetpack Compose: Modern, maintainable Android apps with clean architecture
- Device features: Camera, maps, location, Bluetooth and background tasks
- Offline first: Room and WorkManager so the app keeps working without a signal
- Payments and notifications: Google Play Billing and Firebase push notifications

## How we work

- Design (2-3 weeks): We design screens that follow Material Design and adapt to phones, tablets and foldables.
- Develop (8-14 weeks): We build in Kotlin and Jetpack Compose in two-week sprints, with a test build for you every week.
- Test (2-3 weeks): We test across devices, screen sizes and OS versions, plus slow networks and low battery.
- Launch (1-2 weeks): We prepare the store listing, set up Play Console and release in stages to catch issues early.

## Results

- Delivery Manager: Fleet app that works offline, sends GPS every 15 seconds, and handles driver shifts and expense receipts. Built with Flutter, Firebase, Node.js and PostgreSQL.
- RSA Garage: Roadside assistance app that connects drivers to nearby garages and parts vendors. Built with React Native, Node.js, MongoDB and Google Maps.
- Fwitty: Festival marketing app that creates branded videos automatically, using FFmpeg for video processing.

## Questions

### Native Android or cross-platform?
If you need iOS too and the app is fairly standard, React Native or Flutter can save money. For heavy device features, background work or top performance, native Kotlin is the better fit. We'll recommend one and explain why.

### How do you handle so many different devices?
We test on real devices and cloud device labs, covering popular models, screen sizes and the older OS versions your users still run.

### Who owns the app and the Play Console account?
You do. The app is published under your Google Play account and you own 100% of the code. We sign an NDA before you share anything.

### What does an Android app cost?
It depends on features and integrations. After a free 30-minute call, we send a written plan and a fixed price within 48 hours. Dedicated Android developers start from $25/hour.
