Handy
I personally use this whenever I have to practice some scales/arpeggios and theres no chance to do it with an actual guitar. The sound is MIDI based which is good enough, the UI is honestly really old fashioned but it sure gives a tool that you can work on. I’m not sure what’s the bigger picture for the app to be used for, but I think this is a really basic tool for any user who just wants to practice/play around on the go for a while.
