FAQ
Questions about this service.
React Native and Flutter are the usual options. The recommendation follows team skills, UI needs, and native module requirements.
It is often faster to ship both stores with a small team, but hard native edges can erase savings. Leeonex is candid about those edges before sprint one.
Yes when a feature needs platform APIs the shared layer does not cover. That path is planned so it does not surprise the timeline.
With careful navigation, typography, and platform conventions, cross-platform apps can feel solid for most product surfaces. Media-heavy or AR/ML-heavy apps may still prefer native.
Yes. Dual-store release planning is part of a complete cross-platform engagement when both launches are in scope.
Critical flows are checked on representative iOS and Android devices or simulators before release. Device fragmentation risk is discussed for Android-heavy audiences.
Sometimes for specific modules. A full rewrite is expensive, so the first architecture choice should match the product’s hard constraints.
