    I’m a bassist in band at school, so this is great to use and it’s very fast and efficient. I’m glad I can have a tuner on hand. Currently, I’m trying to learn ukulele at home and I just discovered I can learn the chords when I press on Tools. That’s great, and not what I expected from a tuner. Great app, and worth getting. I’d recommend it.

    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.
