Answer
PWA vs native app: what does each cost?
Building a PWA typically costs 30-50% of an equivalent native iOS + Android app because you ship one codebase to three platforms (iOS, Android, desktop). Maintenance is roughly one-fifth: no app-store review, no separate release trains, no platform-version fragmentation.
Where PWAs save money
Single codebase; instant updates without store approval; no $99/year Apple developer fee for distribution outside the store; no Google Play cut on transactions handled off-platform.
Where native still wins
Games, AR/VR, deep background sync, App Store discovery on iOS (still the dominant install surface for many consumer categories).
When to pick each
Utility, content, SaaS, ecommerce → PWA usually wins on cost and time-to-market. Consumer social with heavy platform integrations → native or hybrid still makes sense.
