Mobile App Development Services

Cross-platform iOS and Android apps built in Flutter from one codebase, tested on real devices by our QA engineers and supported after launch.
Cross-platform apps

One codebase for iOS and Android

Cross-platform apps in Flutter: one codebase that runs on both iOS and Android, so you launch sooner and pay for one build instead of two.

Scope sized to your project, from a simple app with a few screens and integrations to apps with interactive charts, animations and offline data.

Testing on real devices by our QA engineers before every release, plus help publishing to the App Store and Google Play.

Support after launch: operating system updates, bug fixes, new features and monthly suggestions for improvements.

Separate native apps for iOS and Android mean two codebases, two teams and twice the testing. A cross-platform build gives you both apps from one codebase, with one team that owns the design, development and testing.
