Cross-platform frameworks typically cut build time 30-40% versus developing separate native iOS and Android apps — a meaningful budget difference for most business apps, where the UI doesn't need anything platform-specific.
Choose cross-platform (Flutter/React Native) when
- You need to be on both iOS and Android, and timeline/budget matters
- The app is standard business logic — forms, lists, maps, payments, notifications
- One team should own both platforms rather than splitting expertise
Choose native (Swift/Kotlin) when
- You need brand-new OS APIs on day one, before cross-platform frameworks support them
- Performance is genuinely critical — games, heavy AR, intensive background processing
- Deep hardware integration is core to the product, not an edge case
What we actually recommend by default
Flutter for most new consumer and business apps — see our deeper comparison of Flutter vs React Native for how we choose between the two cross-platform options specifically.
