Are you a musician? Do you need to tune up your instrument? Use Cleartune Chromatic Tuner manufactured by Bitcount. This tuner is compatible with almost every musical instrument so there won’t be any need of carrying a devoted tuner.

Besides iPod Touch, this application can also be used with iPhone, and iPad. It also acts as a pitch pipe or a tone generator. You would be thinking about its working mechanism. Well! This application identifies musical notes through the built-in mic of the iPhone or your iPad. I must add that if you are a 2nd or 3rd generation iPod Touch user, you would need an external microphone.

Cleartune can be bought at the App Store for $3.99.
