    One app for iPhone and Android

    You want both platforms without paying for two apps and two teams.

    Mobile app development for iOS and Android from one codebase, usually Flutter, with React Native or fully native apps when that's the better fit. We scope which features need native code before you commit to a milestone.

    • Flutter app development, native where it matters
    • React Native and native Swift or Kotlin work
    • One codebase, two store listings
    • A build you can install at every milestone
    Crumb Count. 82,000+ lines of Flutter across 13 feature modules, live on both stores.

    Migrations without a rewrite freeze

    Your app is built on something you've outgrown, and you can't stop shipping to fix it.

    We migrate production apps one module at a time: GetX to BLoC, FlutterFlow exports to maintainable Flutter, or React Native to Flutter, so releases keep going while the architecture changes underneath.

    • GetX to BLoC or Riverpod
    • FlutterFlow to hand-written Flutter
    • React Native to Flutter
    • A trade-off log you can read later
    Consumer fintech & commerce. Core app architecture migrated from GetX to BLoC in production.
  3. Working buildsWeeks 2-7

    Live Activities, widgets and health data

    Your app needs a phone feature the framework doesn't cover on its own.

    We write the Swift and Kotlin that cross-platform frameworks can't: iOS Live Activities and the Dynamic Island, lock-screen and home-screen widgets, and HealthKit and Health Connect behind one API, connected to Flutter through platform channels.

    • Live Activities and Dynamic Island
    • Home-screen and lock-screen widgets
    • HealthKit and Health Connect integration
    • Camera, notifications and background tasks
    Crumb Count. Live Activities, Dynamic Island, widgets and HealthKit / Health Connect, shipped.

    Apps that work offline

    Your users lose signal, and right now the app loses their data.

    Offline-first app development: the app keeps working with no connection and syncs once it's back, with a conflict policy per type of data instead of one rule that overwrites the wrong thing.

    • Local-first storage with background sync
    • A conflict policy per type of data
    • Deletes and migrations that survive sync
    • Consent fields kept out of automatic merges
    Crumb Count. Offline-first sync with nine per-datatype conflict policies.

    Live location and real-time apps

    You're building a running, delivery or ride app, and the map has to be right, live.

    Background GPS tracking on iOS and Android, live spectator maps, real-time leaderboards over WebSockets, and MQTT live location for dispatch apps, built to survive a dropped connection mid-trip.

    • Background location on iOS and Android
    • Live maps for spectators and dispatchers
    • Real-time leaderboards over WebSockets
    • MQTT driver tracking and dispatch
    Kompete. Every runner, live on one map, ranked before anyone finishes.

    App Store and Google Play publishing

    Your app is built, and review keeps rejecting it.

    We handle getting it published, including the parts review is strict about: health data permissions, background location, payments and privacy labels. If your app was rejected, we fix the cause and resubmit.

    • Store listings and submission
    • Fixes for App Store and Play rejections
    • Privacy and permission declarations
    • Release builds you control from your accounts
    Kompete. Live on the App Store and Google Play.

Questions, answered.

Flutter, React Native or native?

Flutter for most apps, dropping into native Swift and Kotlin when Flutter can't keep up. If your app already runs on React Native or native code, we work in it rather than forcing a rewrite.

Can you add native iOS features like Live Activities to an existing app?

Yes. We've shipped Live Activities, the Dynamic Island, widgets and HealthKit / Health Connect through platform channels in a Flutter app.

Will you publish the app for us?

Yes, from your own App Store and Google Play accounts, so the listing, the keys and the reviews stay yours.

Can you take over a mobile app someone else built?

Yes. A scoped audit finds the actual cause, then you get a fixed quote and a documented fix.

How quickly will I see something working?

The first milestone ships in weeks, not months, and ends with a build you can install.
