★★★★★ abigail bandong · May 12, 2026

This app is really easy to use. If you want to tune the string, you just have to press the chord like d or an in the app, it’ll show, and then play the same chord in your guitar, and it will show if you have to go higher or lower! I really recommend this app! You don’t even have to pay
