User reviews

Reliable

Been using this tuner for years. Works great.

Basic great, but start with Pro.

Great app!—have recommended it to several friends…Ads, as usual, are obnoxious

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.

Better than Boss and Shure!

Better than my boss tu3 and my Shure GLXD16+ Digital Wireless Guitar Pedal System. Both professional standard units. The wave signal is easy to see and quickly adjust my tuning. I am meticulous about intonation. I only play 5 n 6 fretless basses. The apps recognition of the E and B string is instant, clear and simple to tune to. Most tuners i’ve used the tuning of the E and B are a bit dodgy. If this format of tuning was available in a stomp pedal i’d buy it. Buy it immediately. Credit where credit is due. This app is brilliant.
Needs a trial as part of the purchase though. I chanced the purchase. $9? ABSOLUTELY WORTH IT!
Also they don’t take your info.
