Just as good as my 40 dollar tuner!
I bought this app and tuned my Gibson guitar with it. After that, I compared the results with a 40 dollar tuner that I bought a few months ago and found that ACCUTUNE WAS PERFECT. I feel so silly for wasting my money on a physical tuner when 99 cents would have got me the same result. Dont make the same mistake I made, buy this app and save your money.
