{
"rating": 4,
"title": "Great app for intermediate guitarists.",
"body": "This app is INCREDIBLY well put together. The notes that make up a chord are color coded. That alone is amazing. You can tell which one is your root, minor third, and perfect fifth. Knowing this is extremely important especially if you plan to play leads. The scale variety is limited, but for an app that’s free, it’s amazing. The chords are expansive enough to present you with Sus chords, but limited if you want to delve into slash chords or sixths and all that jazz. It’s definitely a feature I’d be willing to pay for if there was a pro version created. Overall I’d say this is a solid app, especially if you’re an intermediary level player, however, even a seasoned guitarist can utilize this app to create slash chords even if the bass note isn’t present.",

"title": "Gorgeous!",
"body": "This app is perfect for a beginner player like me. It made learning the notes on the fretboard so easy. I dig the “Hold to change key” feature. Thank you for your hard work. It would probably be nice to have more scales for more advanced players or to have an option to create our own.",
