Customer Reviews

Works well except

Every time I close out of the app to do something else upon returning the sound does not work. No metronome or tuner without sound.
I have been very unhappy with the app developers not responding to my emails.
I just want to know this will be fixed!

Best Guitar App Available!

This has been the one of the most useful and helpful apps I have ever purchased. The tuner is spot on. The Chords, Scales, and Chord Finder utilities are incredibly sophisticated.

Highly Recommended for every guitarist!


Tuner stopped working on my 4s, seems to have lost access to mic. Tech support page offline. Metronome sometimes has no sound. Weak offering.
