Native apps (built separately for Android using Kotlin/Java, and iOS using Swift) offer the best performance and full access to device features, but cost more since two separate codebases are built. Hybrid/cross-platform frameworks like Flutter and React Native let us build one codebase that runs on both Android and iOS, significantly reducing cost and development time while still delivering near-native performance for most business apps. For most small-to-medium business apps (ordering, booking, service, loyalty apps), we recommend Flutter — fast to build, cost-effective, and looks great on both platforms.
