Legacy Migration

Modernize Your
App Stack

We migrate apps from React Native, Xamarin, native iOS/Android, and legacy platforms to Flutter. One recent rebuild shipped in six weeks, with the existing app live the whole time.

For large apps, we migrate screen by screen with your existing app running in production. For smaller, focused apps, a full rewrite can ship faster. We match the approach to the project.

Xamarin and .NET MAUI deadline: Apple requires the iOS 26 SDK from April 2026. If your app still runs on Xamarin, it won't pass App Store review without action.

Migration Track Record

6 Weeks to ship a full Flutter rebuild of a legacy event scanning app.
0 Features lost in that migration from legacy to Flutter.
0 Days of downtime during migration. Your app stays live throughout.
2 Platforms from one codebase after migration. iOS and Android, always in sync.

What We Migrate

React Native to Flutter

Move from JavaScript bridges and native module headaches to compiled Dart. Better performance, single rendering engine, and a unified widget system.

Xamarin & .NET MAUI to Flutter

Escape the shrinking Xamarin ecosystem. Flutter's active community, Google backing, and mature tooling provide a stable foundation for the next decade.

PowerApps & Oracle WebForms

Replace low-code limitations with a real engineering platform. Full control over UI, performance, and integrations without vendor lock-in.

Native iOS/Android Consolidation

Merge separate iOS and Android codebases into one Flutter app. Cut maintenance in half, ship features to both platforms simultaneously.

Why Migrate to Flutter?

End the Dual Maintenance

Two codebases means two bug lists, two feature backlogs, two teams. Flutter gives you one codebase for iOS and Android that compiles to native ARM code.

Future-Proof Your Stack

Flutter supports mobile, web, desktop, and embedded from one codebase. As your product grows, your app grows with it without starting over.

Keep Your Users

Whether we migrate in phases or do a full rewrite, your existing app stays live until the new one is ready. No gap in service, no lost data.
