PitchFork is a pitch fader for your iPhone! Slide your finger on the screen to change the speed or pitch of any song in your Music library. Its as simple as that.
You can adjust speed or pitch independently, or both at once – just tap to switch modes in the lower left corner. Double tap anywhere to reset speed and pitch to normal.
PitchFork only works with purchased songs downloaded to your iPhone. Make sure your music is downloaded or synced from iTunes to play it in PitchFork.
