  • Best Tuning App Ever

    MaddProfessor

    “I've downloaded many tuning apps before and this one is by far the best. Easy to use, super user-friendly, and they have a bunch of fun different chords and songs to help you learn new music. I highly recommend.”

  • Well-Designed App

    Rose the Black Cat

    “I mostly use this for tuning my guitar, which this app makes ridiculously easy. It also has a large selection of songs to play along to and it helps show you which chords to play as well how to make the shapes with your fingers.”

  • Got me back into playing

    Tuliketsune

    “I got this app to tune an old guitar, and noticed it has a feature that autoscrolls as I play chords to famous songs. For some reason, this was a lot more motivating for me than any other way of practicing guitar. Now I'm actually practicing and remembering the names of chords 🙂”

  • Secret weapon

  • This is the best guitar tuner ever.

    Caleb Schafli

    “It tunes your guitar accurately so you can get the best sound. I like all the other little games as well because they teach you how to play different chords and you can learn to identify the chords by listening to them and it is all offline.”

  • Great to tune and play

    Lynae T

    “I love how easy it is to tune and find and play my favorite songs.”
