Freakin amazing tuner

By far the easiest to use for the most accuracy. The UX idea of the waveform is fantastic. I use it while repairing basses.

The Best

Perfect tuning for Bass, Ukulele, Guitar and Banjo. Maybe not for Piano. Best to hire a piano tuner.

Best tuner app out there. Highly recommend for True Tone.
