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.

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. Overall, it's a great app for beginners and is a wonderful resource for a pretty reasonable price.

Not only is it a tuner (best app tuner I've used personally) but it also has a metronome, games, chords, and a plethora of instruments to choose from and it's SUPER easy to navigate. I love it! Thanks for making an awesome app. From one musician to another, THANKS!!!
This is the best guitar tuner ever.

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

I used to not want to play my guitar because tuning it was such a pain, but then I got this app and now it’s SO fast! I'll be with people and I’ll tune my guitar with this app then they go “woah that was fast!”. 10/10 recommend.
