# Mobile App Development

> Native and cross-platform mobile apps with the polish users expect and the architecture teams can scale.

We ship iOS and Android products using React Native, Flutter, Swift, and Kotlin — choosing the stack that fits your product, team, and timeline. Beyond screens, we design offline-first data flows, push and deep-link engagement, app store readiness, and secure API integration. The result is mobile software that feels native, performs under real network conditions, and is straightforward to extend after launch.


## Key Capabilities

- **Cross-Platform Delivery**: Shared React Native or Flutter codebases when speed and consistency matter; native when they do not.
- **Native-Grade Performance**: Smooth animations, efficient lists, and platform conventions that feel at home on iOS and Android.
- **Offline-First Architecture**: Local persistence, sync strategies, and graceful degradation when connectivity is unreliable.
- **Engagement & Deep Links**: Push, in-app messaging, and deep linking designed for retention — not notification spam.

## Technologies We Use

React Native, Flutter, Swift, Kotlin, Firebase, Expo, App Store, Google Play

## Our Approach

1. **Discovery**: Product goals, platforms, and constraints
2. **Design**: Mobile UX patterns and prototypes
3. **Development**: Feature delivery on chosen stack
4. **Testing**: Device matrix, automation, and beta
5. **Store Launch**: App Store and Play release readiness
6. **Support**: Updates, crash triage, and OS changes

## Budgets of All Sizes

We work with budgets across the full range. The team adapts scope, size, and engagement model to what you can spend, without lowering the bar on how we build.

- **Enterprise**: Full delivery teams for complex platforms, with the security, compliance, and process rigor large organizations expect.
- **Growing Teams**: Flexible engagements that scale with you. Add capacity when you need it, scale back when you don't, without renegotiating from scratch.
- **Small Business & Startups**: Lean, focused builds that get the essentials right. We help you trim scope, not quality, so a modest budget still ships a solid product.

## Why This Matters

- **Broader Reach**: Meet users where they already spend time — on phones, online and offline.
- **Faster Launch**: Smart stack choices that ship value without unnecessary dual-codebase cost.
- **Efficient Delivery**: Shared foundations where they help; native investment only where it pays off.
- **Polished UX**: Apps that feel intentional, responsive, and trustworthy on every device.

## Frequently Asked Questions

### Does OOZOU build native or cross-platform mobile apps?

Both. We build native apps in Swift and Kotlin, and cross-platform apps in React Native and Flutter. We recommend the approach per product based on performance needs, team plans, and budget, not on a house preference.

### Which technologies does OOZOU use for mobile development?

Swift and Kotlin for native work, React Native with Expo and Flutter for cross-platform, Firebase for common backend needs, and full App Store and Google Play release management.

### Can OOZOU take over an existing mobile app?

Yes. We audit the codebase first, then agree a plan to stabilize releases and improve the app iteratively, whether we built the original or someone else did.

### How long does it take OOZOU to build a mobile app?

It depends on scope, but most first releases take a few months from kickoff. We start with discovery and design, then build in short iterations, so you are testing working builds within the first weeks.
