"title": "Essential app for a guitarist",
"body": "If you are serious about expanding your chord and scale vocabulary, this app is the best. The interface is very flexible and you can customize it to focus on shapes vs intervals. You can customize existing scales and chords and save the new ones. Any tuning you play in can be used within the app. Also chord and scales can be saved as photos. It allows you to quickly input a note progression on one string, and it automatically populates them in the rest, and if it matches an existing scale, it will let you know. To shift the key, all you have to do is select whichever key you want and all the notes adapt to the new key. That’s just to name a few excellent features of this app.",

"title": "Everything I’ve ever wanted in a guitar app",
"body": "Thank you for building this. I had built a very basic version of this ages ago using HTML mapping and always wanted to be able to turn it into a proper app. The information here is fantastic and is literally showing you how to speak guitar like a language. I wish every guitarist who wants to be fluent on their instrument to take time to understand the patterns and why the fretboard is set up as it is. I use this every single day and being able to take time to study the guitar without even needing to pick one up is something I’ll be grateful for as long as this exists. I get better and more confident as a guitarist every single day now.",

"title": "Amazing app by responsive developer",
"body": "I have been studying guitar for about 4 years, and THIS is the app I’ve been waiting for! The ability to explore scales, triads, modes, build your own diagonals, etc. it’s amazing. Now we’re adjusting the scale colors to match Scotty West’s Absolutely Understand Guitar program. Then there is the training element … Oh, and when I’ve had questions, Nazar has been quick and thoughtful in his responses. I can’t speak highly enough of my experience.",

All the others are miss something or just don’t quite present the fretboard right or wont show the interval and note. Then the trainer games are perfect. Even the guitar sound is good. Many others have more sounds, but they’re all terrible.",
