Mobile App Development for iOS and Android

An app is not finished when it runs on your phone. It is finished when it survives store review, handles a flaky connection on someone else's train, and can be updated without breaking the version already installed.

What you get

What the work actually includes

  • One codebase, both stores

    React Native or Flutter, chosen for your case rather than our convenience, with native modules written properly where the cross-platform layer runs out.

  • Offline and flaky networks

    Local persistence, queued writes, and conflict handling, so the app degrades gracefully instead of spinning.

  • Push and deep links

    Notifications wired to real events, and links that open the right screen whether or not the app was already running.

  • Store submission

    Listings, screenshots, privacy declarations, and review responses. We have been rejected before and know what for.

  • Release channels

    Staged rollouts and over-the-air updates for the JavaScript layer, so a bad build is a rollback rather than a week in review.

  • Analytics and crash reporting

    Real usage and crash data wired in from the first release, so decisions about what to build next come from what people actually do, not a guess.

  • Accessibility on both platforms

    Screen reader labels, dynamic type, and target sizes checked on real iOS and Android devices, not assumed to carry over from the design file.

Tooling

What we build it with

Chosen because it fits the problem, and because you will be able to hire someone who knows it after we hand over.

  • React Native
  • Flutter
  • TypeScript
  • Expo
  • Firebase
  • Node.js
Questions

Mobile Applications, answered plainly

React Native or Flutter?

React Native if you already have a React web codebase and want shared logic and overlapping hiring. Flutter if the interface is heavily custom and you want identical rendering on both platforms. We recommend one after seeing the designs, not before.

Should we hire native iOS and Android developers instead?

For most products, no. The cross-platform layer covers it. Go native when you are doing sustained heavy work on the GPU, the camera pipeline, or Bluetooth peripherals. If you are in that case we will tell you, rather than taking the project anyway.

How long until it is in the stores?

Two to four months for an app with a backend, review included. Apple review is days rather than weeks now, but a first submission usually turns something up: privacy labels, a missing account-deletion route, or a login Apple wants to test.

How much does mobile app development cost?

A simple app with a handful of screens and no backend can be weeks of work. Anything with accounts, push notifications, and a real backend behind it is typically two to four months. We quote per phase so you see the number before each stage starts, not as one figure covering an open-ended scope.

Do you build a tablet or web version alongside the phone app?

Yes, and React Native or Flutter make that cheaper than starting again, since most of the logic and a good share of the layout carries over. We scope the tablet and web variants separately, since the interface usually needs real rework rather than the phone screens simply stretched wider.

What else we build

Most projects need more than one of these, and they are usually cheaper together than sequenced apart.
