Restoring KEEL Pro on a new iPhone
Open KEEL, tap PRO (top right), and tap Restore purchase at the bottom of the sheet. As long as your iPhone is signed in to the same Apple Account used for the original purchase, KEEL Pro unlocks immediately and removes all adverts.
Microphone permission is turned off
KEEL needs microphone access to detect your vocal pitch in real time. On your iPhone, open Settings → Apps → KEEL and turn on Microphone.
No sound when playing reference tones
Turn up your iPhone's media volume with the side buttons while playing a reference tone. If you are using Bluetooth headphones, disconnect and reconnect your audio device while KEEL is stopped, then tap Play Reference again.
