Cross-Platform App Development (Flutter & React Native)
A common misconception is that cross-platform means a compromised app — laggy, generic, a step behind native. That was truer a decade ago than with today's Flutter and React Native, both of which render genuinely native views and hit 60fps on everyday hardware. The real advantage is one codebase shipping to iOS and Android at once, which matters most for startup MVPs testing product-market fit on a limited runway, or teams maintaining one feature set long-term. It isn't right for everything: apps leaning on cutting-edge platform APIs or console-grade performance are usually better off native, and we say so upfront rather than force-fitting a framework. Where it fits, we share business logic and data layers across platforms while giving navigation and key screens native-feeling polish.
What's included
Single Flutter or React Native codebase (framework chosen per project) targeting both iOS and Android
Shared business logic, state management, and API layer with platform-specific UI adjustments where needed
Native module bridges for camera, biometrics, or push notifications where the framework needs platform-specific code
App Store and Google Play submission handled together, including platform-specific screenshots and metadata
Why runIT
We recommend Flutter or React Native based on your team's needs and long-term maintenance plans, not a default preference, and we'll tell you honestly when native is worth the extra cost.
We reserve platform-specific code for where it actually matters — navigation gestures, haptics, permission dialogs — instead of pretending one UI can look right everywhere.
Shared logic means a bug fix or new feature ships to both platforms from one codebase, cutting QA cycles roughly in half compared to maintaining separate native apps.
As smooth as a software deploy.
Sprint-focused, transparent, measurable. You see what we do at every step.

Frequently asked questions
Will a cross-platform app feel noticeably worse than a native app to our users?
With modern Flutter or React Native, most users won't notice a difference in everyday use — scrolling, transitions, and basic interactions are smooth on current-generation devices. Where it can show is in highly custom animations or deep OS-specific features. We flag those cases during planning and either build a native module for that one piece or recommend native development outright if it's central to the product.
