> iOS, Android and web from one Flutter codebase. Faster to ship, cheaper to maintain, with AI features where they help. Weekly builds and full code ownership.

One codebase for phone, web and desktop. The same polished app on every screen.

We build Flutter apps that look and feel consistent across iOS, Android, web and desktop, from a single codebase your team can maintain.

## Problems we solve

- We need the app on every platform and can't afford separate teams: Three codebases means three times the cost and three times the bugs.
- Our app looks different on every device: Inconsistent layouts make the brand look careless.
- The app has to work where the signal is weak: Field teams lose work when the connection drops.
- Our Flutter code turned into a tangle: State lives everywhere and every change breaks something.

## What we build

- Cross-platform apps: iOS, Android, web and desktop from one Flutter codebase
- Custom interface: Your brand's look, consistent on every screen
- Offline mode: Local storage and background sync for field teams
- Native integrations: Platform channels for camera, GPS, Bluetooth and other device features

## How we work

- Scope (1 week): We define features and target platforms, and plan the work into sprints.
- Design (2-3 weeks): We design screens that adapt to phones, tablets and larger screens, and test them as a prototype.
- Build (10-16 weeks): We build in Flutter with a test build every week, so you can try progress on real devices.
- Deploy (2 weeks): We publish to the App Store, Google Play and the web, and set up crash reporting and analytics.

## 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.
- Example: Claims app: For example, for an insurer we would build a Flutter app where customers file claims with photos and track each step.
- Example: Property viewing app: For example, for an agency we would build a Flutter app with listings, maps and viewing bookings on phone and web.

## Questions

### Flutter or React Native?
Both are good. Flutter suits apps that need a consistent custom look on many platforms. React Native suits teams already working in React. We'll recommend one based on your app and your team.

### Have you built Flutter apps before?
Yes. Delivery Manager, a B2B fleet app with offline mode, GPS tracking and driver shifts, was built in Flutter with Firebase, Node.js and PostgreSQL.

### Who owns the code?
You own 100% of the code and the store accounts. We sign an NDA before you share anything.

### What does it cost?
After a free 30-minute call, we send a written plan and a fixed price within 48 hours. Dedicated Flutter developers start from $25/hour.
