User reviews

Perfect

This is an ideal tuner. It's display is simple and it works with an instrument in any key with A at any pitch.

perfect for a quick tune

I've used this app for years with an acoustic guitar and appreciate its' functionality. I reads quick, shows tuning clearly and does not mind that I don't use standard tuning. I still try others for comparison, but this is the one I hold onto.

Works when it wants to!

Just a couple of seconds and it won't register your voice! Waste of money! Don't buy it!

Amazing!

Amazing app great value for the price!!! Totally recommend if you can't tune and have an instrument that needs tuning!!!

iOS 7

Dissatisfied the tuner does not work on iOS 7 before the upgrade I loved the performance of the tuner but now it doesn't even do anything considering I actually payed for this app I am very dissatisfied
