How do I use Listen?

Tap Start listening, allow microphone access, then play one string or note at a time. The large note shows what Forever Tuner hears. The meter and cents tell you if it is flat or sharp.

How do I match by ear?

Choose Play a note, then tap one of the six standard guitar strings or select any note and octave. Tap Stop when you are done.

Why can’t I hear or detect a note?

For listening, check microphone permission and try a quiet room with a clear single note. For reference tones, check your device volume and selected audio output.

Does Forever Tuner need an account or subscription?

No. It is free, with no ads, account, or in-app purchases.
