Cross-platform apps without the compromises

For the majority of B2C and B2B apps — yes. If your product needs to run on iOS and Android, uses a standard navigation model, and does not depend on platform-extreme features like deep ARKit scene reconstruction or system-level Android services, cross-platform will deliver a native-quality result at materially lower cost. The cases where we recommend going native are narrow: apps that need GPU-level custom rendering, CarPlay/Android Auto integrations, or products where one platform is so deeply tied to OS internals that a JavaScript or Dart abstraction layer becomes a liability.

Honest answer: there are limitations, but they are narrower than the marketing on both sides suggests. Platform-specific UI patterns sometimes need extra work to feel right on each OS — we budget for that explicitly. Some deep OS APIs (HealthKit depth, ARKit scenes, Wear OS data layers) require native module bridges, which add complexity. And when Apple or Google ships a major OS update, you may need to wait for the framework to catch up before using the newest APIs. These are real costs — but for most apps they are smaller than the cost of maintaining two separate codebases.

For the apps most companies build — yes, comfortably. Flutter renders at 60/120 fps on supported devices with its own Skia/Impeller engine, with no JavaScript bridge overhead. React Native has a JS thread but handles standard navigation, lists and forms without visible jank on modern hardware. Where performance becomes a genuine concern is in apps with heavy custom animation, real-time graphics processing, or sustained CPU/GPU workloads. We benchmark early in the project and flag before you are committed if native is the correct answer.

Yes, and we have done it. The approach we recommend is feature-by-feature migration rather than a big-bang rewrite. New features are built in Flutter (or React Native) while the native apps remain live. Screens are migrated incrementally as they come up for redesign or significant change. This keeps the product shipping throughout the migration and lets you validate the cross-platform approach on real users before committing fully. Full rewrites are only advisable when the native codebases are in poor shape and the app is due for a complete redesign anyway.

In our experience, cross-platform typically costs 60–70% of what two native apps would cost — not 50% as some vendors claim, because platform-specific work (store submission, native modules, OS-specific UX polish) still takes real time. Where the saving is most significant is in ongoing maintenance: one codebase means one dependency upgrade cycle, one test suite to maintain, and one team to retain. Over a two-to-three-year product lifetime, the total cost difference is substantial.
