A live preview on every device
See and test your game while you iterate — on a simulated frame or on your real phone.
Klorv embeds a dynamic device frame at the heart of the editor. Every change proposed by the AI is applied and replayed immediately, with no manual build or external device pairing. You stay in the creative flow.
Five frames are available (iPhone, Android, tablet, desktop) with portrait and landscape orientations. Switch in one click to verify menu legibility or playability in an alternate orientation.
For real-device tests, Klorv integrates with Expo Go: a unique QR code per project launches the game on your phone in seconds — perfect for validating touch controls, performance, and audio under real conditions.
What you can do
Interactive device frame
iPhone, Android, tablet, or desktop, all natively simulated inside the editor.

Display the generated code while the preview plays, to understand what's happening.
Built-in analytics view
Preview the dashboard (rolling out) without leaving the editor.
Expo Go QR code
Scan and test on your real phone in seconds.
Instant refresh
No manual build: every chat message updates the preview.

Good to know
- A stable connection is recommended for QR scanning: Expo tunnel runs in development mode.
- The desktop preview simulates the window — a real-device test stays mandatory before publishing.
- Some native features (camera, secure enclave) require a dedicated build to be tested.
