Ship iOS and Android together by sharing one codebase.
8-week sprint: weeks 1–2 discovery and UI, 3–6 core features, 7 QA, 8 store release.
Shared components, a stable design system and early device testing reduce risk.
Add native modules only when truly needed — otherwise you lose speed.
Have screenshots, privacy policy and a crash-free build ready before week 7 for store review.
