I'm surprised no one's written this tuner up before. This is the first and best tuner I've found on the iPhone. There are a few free ones, and several other paid ones, but this one, is hands down, works the best and looks the best. Clean and clear interface + accurate tuning make this one the champ. One of the first apps I every put down money for and I've been using it for over 2 years now.
