React Native — JavaScript ecosystem fit
Uses React and JavaScript/TypeScript — a natural fit if your web application is already built in React/Next.js (see Web Application Development), since some logic and team knowledge can carry over.
Flutter — consistent rendering across platforms
Uses Dart and renders its own UI layer rather than bridging to native components — often praised for pixel-consistent UI across iOS and Android, at the cost of a less JavaScript-familiar ecosystem.
Performance
Both are genuinely production-capable for the large majority of business app use cases — performance differences matter most for graphics-heavy or animation-heavy apps, less so for typical forms/data/workflow apps.
A practical way to decide
If your team or existing codebase is React-based, React Native reduces context-switching. If pixel-perfect cross-platform consistency matters more than JavaScript-ecosystem overlap, Flutter is a reasonable choice. Neither is a universally "better" default.
Questions
Does LATYNEX have a default preference?+
No fixed default — the choice follows your existing stack and specific requirements, decided during scoping.
Which has better long-term community support?+
Both have large, active communities — neither is a fringe or risky choice at this point.
Can we switch frameworks later if we choose wrong?+
Technically possible but a substantial rebuild — worth deciding deliberately upfront rather than assuming an easy switch.
