Well Done!

This is simple program that will speed up learning guitar. It’s fun comprehensive, and pushes you. Enjoy the fun !

Almost Great

I’ve enjoyed this app so far, but it seems that there is a bug in the beginner string drill where sharp notes are played but there’s no option to select a sharp. This doesn’t seem to be an issue in the other beginner modes.

Response from developer

Hi, I'm sorry you experienced this. I just verified that this is indeed a valid bug. I'm pushing a fix for this right away that should be available within the next day.

Practice needs work

Tried the “name the note” practice at beginner level. I’m an advanced intermediate level player and got all the notes correct but the app says I got 90%. I tried at least 5 times so there is a counting error somewhere in the code that is causing an error.

Response from developer

Hi, Thanks for taking the time to report this and for testing it 5 times to confirm it wasn't a fluke. You found a real bug. The scoring on a perfect round was off by one (10/10 was reporting as 9/10 = 90%). It's fixed in the next update. Sorry for the headache! - Brandon

Game changer

So I had a couple hours to kill and really explored the app. There isn’t anything that this app can’t show you. Extremely informative. Pro version is an absolute must 🤘🏽

Get it

Been playing for 20+ years, and while I’m no pro, I’ve bounced around my share of apps. After less than a minute in this app the lifetime purchase was a no brainer. My only issue so far is not being able to change tunings…tapping the button does nothing. Custom tunings would be a great add.
