What this service covers

We build mobile apps for iOS and Android, usually from a single Flutter or React Native codebase. For apps that lean hard on device hardware, such as Bluetooth peripherals, AR or background location, we write native Swift and Kotlin where it matters.

The app is only half the work. We also build the API and admin tools behind it, set up push notifications and analytics, and handle App Store and Google Play submission, including the review back-and-forth.

Releases go out through automated build pipelines, so testers get a new build on TestFlight and Play internal testing every week without anyone archiving builds by hand.

What you get out of it

The results clients typically see. We agree the measures that matter to you during discovery.

  • 01

    Both stores from one codebase

    One team and one codebase for iOS and Android, which typically saves 30–40% against two native builds.

  • 02

    Approved on the first or second submission

    We prepare privacy labels, screenshots and review notes so store approval does not delay launch.

  • 03

    Crash-free sessions above 99.5%

    Crash reporting and staged rollouts catch problems before they reach every user.
