Practice makes perfect! Listen to tracks from your Music library over and over again until you get it right.

Soundproof is designed to help you improve by making it easy to repeat the tracks you want to learn, while it automatically monitors the time you spend practising.


“Really useful app. I’ve been using it to practice some difficult songs and the scrubber feature is so much better than anything else i’ve used. Also the marker feature for looping sections of a song has helped me nail things i struggled with before. Great app.” — Catamaran410

“This is exactly what I was after - allows me to focus on a section of the song Im learning and loop it perfectly so I can get it just right” — Capnlukeron

“Really like this app. Simple to use and very intuitive. I particularly like the loop feature for honing tricky sequences” — Thamagicnumber

Ratings and Reviews

Looping but no slow down


This app can be picky about loading songs from iTunes. The looping function works fine, but I haven't been able to use the slow down function, which is half the point of the app.

Developer Response

Thanks for leaving a review. The slow down function works without problem to our knowledge, although perhaps you are playing via AirPlay or Bluetooth speaker?

As for which songs you can play, this is a limitation of all apps that play from Music Library. If you purchase the track from iTunes you should have no problems
