What clients usually ask
What's the difference between PWA and a real app?
PWA = web app with native look. Pros: no app store wait, instant updates, cheaper. Cons: no store listing, limited hardware access.
Is the PWA as good on iOS as on Android?
Mostly yes. iOS Safari has supported PWA for years, push notifications since 16.4 (April 2023). Android is somewhat friendlier.
When is Flutter (5900 EUR) worth it over PWA (2490 EUR)?
If you want to be in the store, need in-app purchases, want to use Bluetooth/NFC, or need to reach older iPhones.
What about offline data?
Service worker caches UI + static data. User data via IndexedDB (built-in). Sync on reconnect.
Can the PWA become a native app later?
Frontend code reusable with Capacitor (~1490 EUR migration), or full Flutter rebuild (5900 EUR).
