Flutter app development for Android, iPhone and web

Flutter lets one codebase run on Android, iPhone, the web, Windows and Mac. Our apps Wasoolo, MDCAT Helper, Basic Ledger and Dot Rivals are built with it, and Wasoolo runs on all five. We build new Flutter apps and take over existing ones.

FAQ

Common questions

Why build with Flutter?

One codebase gives you an Android app and an iPhone app, and a web or desktop app if you need one. You pay for one app instead of two, and every update reaches all platforms at once.

Can you take over a Flutter app someone else built?

Yes. We read the code first and tell you honestly what is good, what is broken and what it takes to fix. Then we fix bugs, add features and publish the updates.

Can you update my old Flutter app for the new store rules?

Yes. We update Flutter, Dart and the plugins, raise the Android target API level, test on the newest Android and iOS versions, and publish the update.

Do you build the backend too?

Yes. We use Supabase, Firebase or Node.js, depending on the app: logins, databases, push notifications and admin panels.

How much does a Flutter app cost?

It depends on the screens, the features and the platforms. After a short chat about your idea, we send you a clear plan and a price before any work starts.
