"rating": 2,
"title": "Inaccurate",
"body": "The app is a great idea but it’s poorly executed. Firstly you have to pay to even use the app but the main problem is how inaccurate it is. Some of the keys it would show were completely wrong compared to the video you’d upload and sometimes it would actually get the right keys but the app would add an extra random key. It’s truly a good idea but this app is too inaccurate and not worth it.",

"title": "Don’t recommend",

The navigation isn’t great, the transcriptions are often off, it’s not smooth. It’s honestly hard to even follow when I’m trying to practice from it.",

"title": "Not good",
"body": "For an app that requires you to pay to use, its features are really lacking, it can’t translate any song well unless it’s only piano, and if it’s only piano, there’s probably already sheet music or an existing tutorial. As it stands, this app is not worth it.",
