The app is crashing or not working

1. Restart your device.
2. Update WhoIsThis to the latest version.
3. Check you have free storage space.
4. Reinstall the app (your subscription isn't affected — use Restore Purchases after).

If it persists, email info@whoisthis.io with your device model, OS version, app version, the screen where it crashes, and what you did just before.
