Mobile App Development

We use Flutter for mobile app development, shipping iOS and Android from a single codebase. MVP-scope apps typically reach the store in 4-6 weeks.

Problems we see

  • Building iOS and Android with separate teams nearly doubles cost and creates behavioural differences between platforms.
  • Store release processes — App Store review, privacy declarations, version management — are underestimated in most projects and push delivery dates.
  • When scope grows unchecked, the MVP stops being an MVP; budget runs out before the app ever ships.

Our approach

  • One Flutter codebase. Because the interface is drawn by the same engine on both platforms, behavioural divergence disappears.
  • We narrow MVP scope to a single verifiable flow. What stays out of the MVP matters as much as what goes in.
  • Store release preparation is part of the project plan — privacy declarations, icon sets, store assets and review time included.
  • Where backend needs are simple we move fast with Supabase or Firebase; where business rules are complex we build our own .NET API.

Process

  1. 01

    Scope definition

    The single main flow for the MVP is agreed. Everything else is written down for later releases.

  2. 02

    Interface design

    Flows designed to platform guidelines and usable one-handed.

  3. 03

    Development

    1-2 week sprints. Each sprint produces a build installable on a test device.

  4. 04

    Test distribution

    Real-device testing via TestFlight and Google Play internal testing.

  5. 05

    Store release

    Store records, privacy declarations, assets and the review process are managed.

What you get

  • One Flutter codebase for iOS and Android
  • App Store and Google Play release setup
  • App icons, splash screen and store assets
  • Privacy declarations and store requirements
  • Release and distribution documentation

Frequently asked questions

How long does mobile app development take?

An MVP-scope app with a single main flow reaches the store in 4-6 weeks. That includes store review time; App Store review usually takes a few days. Multi-user apps with payments or complex backend integration can run 10-16 weeks.

Should we choose Flutter or native?

If your app is interface and business-logic driven, Flutter's single codebase cuts both cost and delivery time roughly in half. For apps that lean heavily on device hardware — advanced camera processing, AR, low-level Bluetooth — native may be the better call. We decide during discovery.

Do you handle publishing to the app stores?

Yes. App Store Connect and Google Play Console setup, privacy declarations, store assets and the review process are handled by us. Developer accounts are opened in your name; ownership always stays with you.

How are post-launch updates handled?

We offer ongoing support agreements covering bug fixes, performance improvements and new feature development. Because Flutter is a single codebase, an update ships to both platforms at once.
