Great app

Easy to use and with a good range of alternate tunings, tuning green line is so easy to see especially at gigs, dark areas etc, recommend it

Just straight up bad

It does not recognize what string I'm playing and has zero ability to correctly tune my guitar for a E-A-D-G-B-E tune as I am new, not to mention that I play the same note twice it gives me two different results and I never edited it and no Matter what I do it never goes green, it's just horrible and hard to deal with your better off finding a different app then this.

Works great for standard.

I think this is a wonderful app for all of the people that haven’t learned how to tune their music instrument yet, but it does have a few bugs that could be annoying if you are into the drop chords or open tunings. I use it when I am in a hurry, and it gets me within an earshot on a string or two and then I know how to finish tuning my instrument from playing over the last six months of my new pass time hobby.
