The app will notify you of your performance through its unique Slow-Mo feature. This occurs when the person using the Music Momentum running app has a current speed value lower than their Target Minimum Speed (TMS) value.
Music Momentum plays your music at a much slower playing rate than its normal rate when triggered. This notifies that you need to pick up the pace in order to get your music playing at its normal speed again.
Create a playlist with all your favourite songs/artists in the music library and start a new session. Once within your session, the app will then process your playlist through the software. So, if at any stage you fall below your target speed, the app will slow down the playing speed of your music. This will immediately notify you of your performance.
In order to get your music back to its normal speed again, you will need to pick up the pace to match your target speed or reduce your TMS to a more comfortable setting if things are becoming a bit too difficult.
