While not extremely precise "Guitar Tuner" App makes up for it with major versatility! I use it for half step down mostly because my KORG guitar tuner SKIPS the "F#" note when downtuning the "G" string 1/2 a step! WHY BUY EXPENSIVE TUNERS TO ACCOMPLISH WHAT THIS APP DOES FOR FREE?! And it's precise enough that even the most proficient guitarist CANNOT determine the slightly imperfect tuning this app produces as it produces 95%-100% accuracy FOR FREE in tuning your guitar properly to the song!

Works great. I wish I could pay, even a small annual fee, to remove the ads. I have my phone with me all of the time, a tuner, not so much. I don't know how many dead batteries. I can tune by ear, but this makes life so much easier with new and newly stretched strings and setting them up. Great tuner.

It's free, and it's chromatic so I use it to tune my harp. It gets a little confused with higher notes (outside of the normal range for guitar tuning) and completely flunked out when I tried to use it to check how bad my piano was, since the piano has multiple strings that SHOULD be the same note - the app is looking for a single frequency. That would be a cool feature, actually, if it could report multiple frequencies at once...I would pay for that upgrade.
