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!!!

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.
AMAZING FAST AND ACCURATE

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.
Very reliable tuner

How to tune your bass

Follow these easy steps for beginners

1 Start in standard In the GuitarTuna app, select Standard tuning. When you’re first starting to play bass, you’ll typically be using the standard tuning: E A D G on a 4-string bass.
2 Pluck a string Start tuning your bass by playing any string with the right tension — not too heavy, not too light. GuitarTuna will listen to your pitch with its built in microphone.
3 Adjust your tune Turn the tuning pegs on the headstock of your bass. You’ll hear the pitch get higher or lower as tension is applied or removed. Turn until the app shows you’re in perfect tune!
