Not good at all

DO NOT get this tuner for anything other than standard tuning. It is hard to understand and it takes massive amounts of time to actually tune anything

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.
