Mobile apps people actually enjoy using

You have an app in mind, or one that isn't working. We design it, build it once for iPhone and Android, and get it into both stores. It still feels native.

How we approach mobile

Selcouth.DIGITAL is a London mobile app development company that designs and builds iPhone and Android apps as a single product. We build with React Native and Expo, so one TypeScript codebase ships to both the App Store and Google Play, and the result still feels native in navigation, gestures and performance. You do not pay for two teams or two sets of bugs, and features reach both platforms together.

We cover the whole path from idea to a running app: product design and prototyping, the build, store submission and release management, then crash reporting, analytics and over-the-air updates so fixes reach users without waiting for store review. You work with the senior people doing the work rather than a sales layer, and the code lives in your own repository from the first commit. We have shipped mobile products for Virgin Red, Virgin Trains Ticketing, Heycar and Shell, and we hand over a release process your own team can run. Whether you are building a first version, rescuing an app that is not working or moving to React Native, tell us what you have and we will say plainly how we would approach it.

Mobile questions

No. We build with React Native and Expo, so one TypeScript codebase ships to both the App Store and Google Play. It still feels native, and features reach both platforms together instead of needing two teams and two sets of bugs.

Yes. Tell us what you have and we will review it, say plainly what we would fix first and whether it is worth keeping or rebuilding. If you are moving an existing native app to React Native, we can plan that move with you.

Yes. Store submission and release management are part of the work, along with crash reporting, analytics and over-the-air updates, so fixes can reach users without waiting for a full store review where the platforms allow it.

It depends on what you need, so we do not publish prices. When the scope is clear we quote a fixed price per phase, and when it is exploratory we work on a day rate. You see the number before we start.
