What we build

One codebase, both app stores

Flutter lets one team ship the same polished app to iPhone and Android at the same time. We plan the architecture so it stays fast and easy to extend as the product grows.

Cross-platform MVPs

Launch on the App Store and Google Play together, in weeks instead of months.

Customer apps

Booking, loyalty, ordering and self-service apps with a consistent experience on every phone.

Business and field apps

Offline-ready tools for teams in warehouses, on sites and on the road.

Real-time apps

Chat, live tracking and instant notifications backed by Firebase or your own APIs.

Apps with web companions

Share business logic between the mobile app and a Flutter web dashboard or admin panel.

Migration to Flutter

Replace two ageing native apps with one modern Flutter codebase, screen by screen.

Why 7T

Why choose 7T

One codebase for iOS and Android

A single Dart codebase and one team, so features reach both platforms on the same day.

Near-native performance

Flutter compiles to native code and renders at a smooth 60–120 fps, with platform channels where native access is needed.

Faster time to market

Hot reload, shared UI and one test suite cut build and release time compared with two native apps.

Easier to maintain

One codebase to update for new OS versions, store policies and features, which lowers long-term cost.

FAQ

Flutter questions

Is Flutter as good as a native app?

For most products, yes. Flutter compiles to native ARM code and renders smoothly, and users cannot tell the difference. We recommend fully native only when an app depends on very specialised device features.

How much faster is Flutter than building two native apps?

Because iOS and Android share one codebase, a first release usually takes noticeably less time and budget than two separate native apps, and every later update is built once.

Can a Flutter app use device features like the camera, GPS and payments?

Yes. Flutter plugins cover the camera, location, biometrics, notifications and in-app payments. For anything else we write a small native module.

Which state management and backend do you use?

We use Riverpod or Bloc for predictable state management, and connect to Firebase or your own REST or GraphQL APIs.
