What's Included

Everything you need,
nothing you don't

Scope

  • Cross-platform builds in React Native or Flutter, or native iOS (Swift) and Android (Kotlin)
  • Product design and prototyping before a single line of code
  • App Store and Play Store submission and release management
  • Push notifications, in-app purchases, and third-party API integrations
  • Post-launch monitoring, crash reporting, and iteration support

Who This Is For

Startups and product teams launching a new mobile app, or migrating an existing one to a more maintainable, scalable codebase.

  • Need one app that runs well on both iOS and Android without doubling the budget
  • Have an existing app that needs a rebuild, refresh, or performance fix
  • Are ready to ship to the App Store and Play Store on a real timeline

FAQ

Questions, answered

Should we build native or cross-platform?

For most startups, React Native or Flutter gets you to both iOS and Android with one codebase at a fraction of the cost and time. We recommend fully native only when the app depends on deep OS-level integration.

Do you handle App Store and Play Store submission?

Yes, we manage the full submission process, including store listings, screenshots, and review compliance.

How much does a mobile app cost to build?

It depends heavily on scope, but most MVP apps we build range from a focused single-flow app to a full multi-feature product over 8-16 weeks. We scope this concretely on the intro call.

Can you take over an app that another agency started?

Yes, this is common. We start with a code and architecture audit so you know exactly what you’re inheriting before we commit to a plan.
