From Matthew Finn:
Cleartune for Android features a unique note wheel interface allowing you to quickly find your pitch, paired with a highly responsive fine-tuning meter for the perfect tune. It is a chromatic instrument tuner and pitch pipe that allows you to quickly and accurately tune up using the built-in mic in your Android device. This application can tune acoustic or electric guitar, bass, bowed strings, woodwinds, brass, and piano instrument that can sustain a ton.
