Notes

Some of the instructions on finding the notes are a bit deceiving, and I’m having trouble understanding what it’s actually telling you to do

Needs improvement

The app is a good idea, but not that well executed. You are greeted on the opening screen with a massive advert for the upscale of a course which is a bit disappointing as you would expect more interface considering this is quite expensive in app land. The app also crashes if you are on a laptop and try to change it to the non laptop screen. The ability for the software to identify the app is ok, but it does skip a lot of the time and that is when the room is very quiet. Overall, as said, this is a good idea, but needs more ergonomics from the front page and less ‘now buy my course...’ when you have just spent money.

My opinion

Solo is a great tool if you use it consistently.

Game Changer

This app should be part of every guitarist's practice routine. Period!

It tackles so many areas that most musicians know they're missing, but often can't put into words. I'd had my eye on it for a while but kept putting off buying it, thinking that learning more fretboard shapes and theory concepts would take my playing to the next level. Those things absolutely help, but they can only take you so far.

After finally taking the plunge and spending just one evening with it, it's completely changed how I think about my practice sessions. It's already given me so many new ideas and highlighted areas I'd been overlooking.

Fair play, Tom—and thank you. I genuinely think every guitarist should have this at their disposal, especially when they're starting to learn intervals and connect the fretboard in a meaningful way. You’ve hit the nail on the head with this one.
