I was trying to tune my guitar when an unskippable ad for the king James bible (with sound!) obscured the whole screen and played for more than a minute with no way to return to tuning. The ad finally ended, and another unskippable christian ad played. I uninstalled. Also, the interface is confusing.

It tunes it flat. I couldn't get it to tune correctly.. the low E was to high and the highE was tune fine . The D and G would not line up it would float back and forth way to fast... there no reason strum cord hard and it reads high then reads nothing.. I played with it a while... just need little tweaks..

The sound of the notes that are generated sound like a real actual guitar. This makes it easy to tune by ear. The app also picks up the sound of your guitar and registers if the string is in tune.

What’s new

Some slight bug fixes that should make the app run smoother and make tuning easier!

Also, ads should be less annoying now!
