Mobile apps

React Native & Expo

One team, one codebase, both stores

React Native with Expo is how we build almost every mobile app: the same code runs on iOS and Android, the team building the app also builds the web platform, and fixes reach users without another pass through review.

React Native & Expo

What matters on this platform

One codebase, two platforms

Most of the code is shared. We write separately only what is genuinely different between iOS and Android, not everything that could be.

Expo, not just React Native

EAS Build for cloud builds, EAS Update for over-the-air updates, and native modules whenever we need something Expo doesn't ship.

The same team on the web

The admin dashboard, the API and the app come from the same people, in the same sprint. No translation between two vendors.

Flutter or native?

We recommend Flutter or native code when they make sense: games, heavy graphics or an in-house team that already knows Swift and Kotlin. We say so when we are not the right choice.

FAQ

Frequently asked questions

Is React Native fast enough?
For business, commerce, membership and service apps, yes. Shopify, Discord and Coinbase run on React Native. Where it falls short, we write a native module for that one feature.
Can my team take over the code?
Yes. TypeScript, Expo, a documented structure and a repository that is yours from day one.
Do you have your own React Native apps?
Yes. GymTime AI, published by WISE IT SRL, is built with Expo and React Native and is on the App Store.
