š± Choosing the Right Mobile App Stack in 2025: Flutter vs React Native vs Native iOS/Android (Our Real-World Approach)
Building a mobile app in 2025 isn't just about picking a technology -- it's about choosing the right tool for your goals.
At Dezoko, we've helped dozens of startups and enterprises launch apps across:
- Flutter
- React Native
- Native iOS (Swift)
- Native Android (Kotlin/Java)
- PWA + web-to-app wrappers
And the biggest question we get is:
> "Which one should we use for our app?"
Here's our honest, real-world take -- based on building 30+ apps across stacks.
š§ There Is No "One Best" -- Only "Best for You"
We don't force one tech.
Instead, we ask:
- Is performance critical (e.g. animations, AR, offline)?
- Do you need rapid cross-platform deployment?
- Is long-term maintainability important?
- Will you build a web version too?
- Do you need 3rd-party hardware or system-level access?
Then we match that to the stack.
āļø Flutter vs React Native vs Native -- Quick Comparison
Stack | Pros | Best For |
|---|---|---|
Flutter | Fast UI, 1 codebase, works on all platforms (mobile, web, desktop), Google-backed | Startups, SaaS, MVPs, pixel-perfect UI |
React Native | Strong JS/React community, reusable web logic, rich plugin ecosystem | Startups with web + app devs, hybrid MVPs |
Swift (iOS) | Pure native, fast animations, full Apple ecosystem access | High-end iOS apps, AR/VR, camera-heavy |
Kotlin (Android) | Best Android experience, latest system-level access | Android-first startups, custom system apps |
