A digital pitch pipe for your smartphone.

Pitch Perfect is a utility app for the musically inclined. It's a digital pitch pipe, so you can take a starting pitch before singing or rehearsing a song. If you're the type who struggles to match a key signature to the name of a key, the app gives you visual aids, so finding your note is as easy as matching what's on your sheet music to what's on your screen. And if you keep a list of songs and the keys they're in, Pitch Perfect keeps that list for you.

With Pitch Perfect, you'll never be up a creek without a pitch pipe again.
