Very Handy!

I've been looking far and wide for a tuner that could help tune for multiple and more complex tunings. As a guitarist and songwriter, I am constantly changing tunings to fit what I love to play and this app makes it easy and painless for me to do so. I recommend this app to any guitarist looking to tune accurately and quickly to any tuning they desire. Thanks for the awesome app!

I love it!

This is the best app for guitar tuning. I like that you have several different options available.

Maybe for the next update, can you block background noise? If you can't, that's okay.
