PitchHitter app for iPhone and iPad

Pitch Hitter is an innovative singing-training system, using your own voice as an aural guide to help you hit the right pitch, everytime!
Improve your vocal intonation, learn to recognise intervals, and pass your aural and sight-singing exams with flying colours!
Using state-of-the-art technology, Pitch Hitter takes an audio sample of your voice, pitch-shifts it to the pitch you need to hit, and along with straightforward and friendly visual feedback, helps you develop a vocal muscle-memory for any interval.
Focus on the same starting note each time and help develop perfect pitch!
Use this for 10 minutes a day, and youll be wondering what was ever so hard about singing intervals accurately!
