Mobile apps for iOS and Android, built once with Flutter
One Flutter codebase gives you native-quality apps on both iOS and Android — at roughly the cost of building one. We handle everything from UX to App Store and Google Play submission, and we stay on to support you after launch.
What you get
- One codebase for iOS and Android
- Real-time sync across devices

What our clients say
Rated 4.9 out of 5 on average by the teams we work with.
“They shipped a RAG assistant in six weeks that our team had been trying to build for a year. Clean code, real answers.”
Marta NdiayeHead of Product, NeuroLedger “Algo Matryx feels less like an agency and more like an extension of our engineering team. Rare combination.”

Why Flutter instead of separate native apps?
Flutter compiles to native code for both platforms from one codebase, so you get near-native performance while paying for — and maintaining — one app instead of two.
How much does a mobile app cost?
It depends on features and integrations. A focused MVP is usually the most cost-effective start. Share your idea and we'll send a free, itemized estimate.
Do you publish the app to the App Store and Google Play?
Yes. We prepare the store listings, handle review requirements and publish under your developer accounts, so you keep full ownership.
Will you maintain the app after launch?
Yes. We offer ongoing support plans covering OS updates, bug fixes and new features.
