Rork
Prompt-to-mobile-app builder (Expo)
Free tier + paidAI app buildersrork.com
What it is
Builds cross-platform React Native + Expo apps for iOS, Android and web, previewable instantly by QR code in Expo Go. Paid plans unlock private projects, source export and App Store or Google Play publishing. Rork Max is a separate $200/mo product that builds native Swift apps.
Why it earns a slot
The mobile-first rival to a0.dev with a faster preview loop — scan a QR code and the app is running on your phone in seconds, no simulator. Max is the only tool here emitting native Swift.
Know before you commit
Free-plan projects are public and cannot be exported or published, so the free tier is a demo only. One message equals one prompt regardless of size, so a button-color tweak costs the same as an auth system.
Getting started
Budget Apple Developer ($99/yr) and Play Console ($25) fees on top of the subscription.
