Tap an app and choose Resign & Reinstall.
Letra re-signs the saved copy with a fresh profile and installs it again, keeping your tweaks and settings. With Stay signed in on, an expired Apple session is renewed in the background — the only prompt you might see is a verification code.
Apps library
Apps library — every app installed through Letra is saved so you can Resign & Reinstall before the free 7-day profile expires.
Stay signed in
Stay signed in — optionally store your Apple ID password securely in the device Keychain so expired sessions renew in the background while re-signing.
