Fantastic app! Only tuner you'll ever need!
This is a fantastic tuner. I have used several others but they didn't even come close to the tight tuning of this one. I actually first bought it to help me tune a $50 PIANO. It worked FANTASTIC. Then I used it on a guitar. Again, it was great. I can't recommend it enough.
Best Tuner in App Store
This is the best tuner on the App Store. Great interface. The performance analyzer feature is invaluable, letting you analyze the pitch of each note as well as the levels; this is a unique feature that I have not seen on any other iOS tuner apps. Highly recommended!!
This is a wonderful tuner The design is like the very expensive versions for a fraction of the price. The strobe tuner is the perfect tool to gain pitch and accuracy. It works instantly.
And thank you for the quick fix when they changed it to IOS 9.
