App development FAQs
The right path depends on your product goals, speed-to-market constraints, and long-term operating model. Native is ideal for deep platform performance and hardware-specific experiences. React Native is great for faster cross-platform delivery with balanced quality and cost. PWA works when distribution friction should be low and app-store dependency is not required.
