5 stars: Struggled for ages for a routine to practice. Had slow chord changes and poor timing. Find this app is perfect as it charts your progress and let's you choose your difficult chord change with the one minute timer and then changes within songs. I use this and then marty schwarz for the songs and strumming. Highly recommend and Justin is such a nice guy he makes you want to improve.
4 stars: So far I am on stage one and learning A and D chord. For last 3 days I have been trying to play songs given in the app for A and D chord but it's not opening. Please look into this matter. I really like how easy guitar learning has been made in this app, but if lessons aren't opening that's a big hurdle. Please do address this issue. I am keen on joining the entire course
5 stars: This is the best learning app that I've ever used! I've been trying out different online guitar courses, and Justin absolutely blows them all out of the water! This app is unbelievable! From the quality of instruction, to the presentation, layout, and design, everything is so beyond what I expected. Amazing! Thank you!
4 stars: Very good, enjoy playing along to the tunes - quite a varied selection - and useful chord practise. Would be good if it could be cast to the TV. Once or twice it has slowed up, not sure whether that's an app, phone or internet connection issue though.
4 stars: Good app, working my way through the levels as someone who has owned guitars for years but never really got...
