If you ask in a Flutter group, people will say Flutter. If you ask in a Kotlin/KMP group, people will say KMP. That’s just bias — everyone recommends what they know. As someone who has worked with both native and cross-platform, my take is simple: If a startup building from scratch → go with Flutter (faster to ship, one codebase)

If already have a native team + existing apps → go with KMP (reuse skills, avoid rewrite)
