Mobile App Development Company
Darwinbark builds mobile apps for iOS and Android - cross-platform with Flutter or React Native for most projects, and fully native Swift or Kotlin specifically when a project's performance or platform-API requirements make cross-platform the wrong tradeoff.
How We Choose the Stack
Not every app should be cross-platform, and not every app needs to be native. Heavy device API usage - camera processing, background location, Bluetooth hardware - pushes toward native, where platform APIs are a first-class citizen rather than a bridge. Standard CRUD apps with a backend API - the majority of business apps - are a strong fit for Flutter or React Native, where one codebase covers both platforms and ships updates to both at once.
What's Included
Every mobile engagement includes UI/UX design as part of the build - the same team designing the screens builds them, cutting the back-and-forth that happens when a design file gets reinterpreted by a different developer. Backend integration connects to REST APIs, either an existing client backend or one we build alongside the app, and every project ships with push notifications, in-app payments where relevant, and full App Store / Play Store submission handled end-to-end.
Avoiding Store Rejection
App Store and Play Store review guidelines shift often enough that a submission built without them in mind gets rejected on things like privacy disclosure or background permission justification. We prepare submissions against current guidelines rather than treating it as a formality at the end of the project.
