# Mobile  
_Development_

Flutter-first cross-platform apps with native performance. iOS and Android from a single codebase — shipped in half the time without sacrificing quality, and maintained by one team instead of two.

What you get

## One codebase.  
Both platforms. _Native feel._

### Flutter-first development

Flutter is our default for good reasons: 60fps performance, pixel-perfect UI on both platforms, a single team maintaining one codebase. We use it because it genuinely works.

### Native iOS & Android when needed

Some use cases genuinely require native development — hardware integration, specific platform capabilities, apps that are deeply OS-specific. We know when to choose which.

### Backend & API integration

We build the mobile app and the APIs it talks to. No handoff friction between backend and frontend teams — one team owns the full stack.

### App Store & Play Store submission

Full submission process included: provisioning profiles, signing, metadata, screenshots, review response. We've done this hundreds of times and know where reviews get stuck.

### Ongoing maintenance & updates

OS updates break things. We monitor for breaking changes and handle maintenance releases so your app stays functional and compliant across new iOS and Android versions.

### Performance & crash analytics

Firebase, Sentry, custom analytics integration. You'll know exactly where your app crashes, which screens are slow, and where users drop off.

Process

## From design to  
both app stores — shipped.

I

### Design & architecture

UX flows, component library, technical architecture. We design for the OS conventions your users expect, not for the designer's portfolio.

II

### Development sprints

Two-week sprints with working builds you can test on a real device. TestFlight for iOS, internal tracks for Android — from week one.

III

### QA & beta testing

Device testing across the iOS/Android matrix, performance profiling, accessibility review. We catch edge cases before your users do.

IV

### Store launch

Submission, review navigation, staged rollout setup. Both stores live at the same time. No staggered launch chaos.

> "We launched on iOS and Android simultaneously. The Flutter codebase meant we had _one team, one sprint, one launch._"

The math on cross-platform is simple when done right: one team, one codebase, two stores. The tradeoff in native feel is close to zero with modern Flutter.

Common questions

## What clients usually _ask first._

Flutter or React Native — which is better?

For most new projects, Flutter. It has better performance, more predictable behavior across OS versions, and a stronger single codebase guarantee. React Native can be the right choice when your team is JavaScript-only or when you have an existing React web codebase you want to share logic with.

Can you work on an existing app?

Yes. We do codebase audits, feature additions, refactors, and platform migrations. We'll tell you honestly what we find in the existing code before committing to a scope.

How long does app review take?

Apple App Store: typically 24–72 hours for first submissions, faster for updates. Google Play: usually 24 hours. We account for review time in our launch planning and know the common rejection reasons to avoid.

Do you handle push notifications, in-app purchases, subscriptions?

Yes — all standard mobile infrastructure. RevenueCat for subscription management, native push notification setup, deep linking, biometric auth. These are solved problems we implement correctly from the start.
