Why Two Codebases Cost More Than You Think
Maintaining separate native apps means every feature, bug fix, and design change gets built twice, tested twice, and can drift out of sync. Teams end up with iOS ahead of Android or vice versa, and inconsistent behavior between them.
Migrating to React Native or Flutter puts your shared business logic and UI in one place. You keep native modules where they genuinely earn it, but most day-to-day work happens once. The payoff is faster releases and lower ongoing cost — not zero effort, but far less duplication.
- One codebase for shared UI, navigation, and business logic
- Native modules retained for hardware, SDKs, or performance-critical paths
- Feature parity between iOS and Android by default
- Fewer places for bugs to hide and diverge
- Smaller surface area to test and release
A Staged Migration, Not a Risky Rewrite
You rarely need to stop everything and rewrite from scratch. A brownfield migration lets you embed cross-platform screens inside your existing native apps and convert flows one at a time, so the app stays shippable throughout.
We map your current features, decide what genuinely needs to stay native, and migrate the rest in an order that reduces risk. Your users keep getting updates while the codebase consolidates underneath them.
- Inventory of current native screens, SDKs, and platform-specific code
- Screen-by-screen migration with the app shippable at each step
- Bridge existing native modules rather than rebuilding them blindly
- Regression testing against the old app's behavior as the baseline
- A clear list of what stays native and why

Frequently asked questions
Do I lose native performance by moving to React Native or Flutter?
For most apps, no perceptible difference — cross-platform frameworks render close to native for typical UI. Where you have genuinely demanding work (heavy graphics, real-time audio/video, tight hardware loops), we keep that in a native module and call it from the shared code. The goal is one codebase, not blind purism.
Can we migrate gradually instead of all at once?
Yes, and it's usually the safer choice. Cross-platform screens can live inside your existing iOS and Android apps, so you convert flows incrementally and keep releasing. A big-bang rewrite is riskier and pauses your roadmap; we avoid it unless your current code is truly beyond reuse.
Which should I choose, React Native or Flutter?
Both are solid. React Native fits teams with existing JavaScript/TypeScript skills and lots of npm ecosystem needs; Flutter shines when you want highly consistent custom UI across platforms. We'll recommend based on your team, your existing code, and your app's needs rather than a house favorite.
