PartPerfect

PartPerfect is the practice and recording app built for singers who use learning tracks.

Load your own learning tracks into the PartPerfect library and use them to practice and record your part — whenever and wherever suits you.

PartPerfect works best with left/right split channel learning tracks, where your singing part is in one ear and the other parts are in the other. Use the pan slider to dial in exactly how much of your own part you want to hear while you practice. As you get more confident, gradually shift the balance until you're singing entirely against the other parts — just like the real thing.
When you're ready to test yourself, switch to the record tab.

Record your singing against your learning track using your device's microphone, then play it back and listen critically. Discard and try again as many times as you need.

Now, analyze your recording against the reference track and see how close you are in pitch. Get a percentage score to help you improve your singing.

Happy with your take? Share it directly from the app — to the Files app, via AirDrop, email, or cloud services like Google Drive, Dropbox, or Box.
