Make the music fit your workout with MusicFit.


Working out to music positively influences your mood and emotions, reduces the exhaustion you feel and raises the levels of endurance, power and strength. Research shows that these effects are stronger when your physical activity and music are in sync. Up till now though, moving in sync meant adapting your activity to the music, or putting a lot of effort in selecting matching music. MusicFit revolutionizes the approach – the music adapts to your movements.


MusicFit generates music on the spot. You don't need to be online or download playlists to use it.
The music you hear is composed and performed by your phone while you are working out, completely “in the moment”. MusicFit tracks your body movements (through the iPhone's sensors) and responds instantly to every change of pace.


MusicFit generates music in 4 different genres (the option mix alternates between the 4 genres).

-techno: sets the genre to techno
-electro: sets the genre to electro
-idm: sets the genre to idm
-chill: sets the genre to chill
-mix: sets the genre to vary

You can change the genre of the music while it is playing by returning to the genre page (back button) and changing your selection.

Musica Combinatoria (MUSI-CO for short) is a young company developing systems for music generation using Artificial Intelligence. MusicFit is the first app demonstrating the potential of our technologies. We would like MusicFit to grow up to be a fully featured sports app, and need your help to take it from the lab to the streets. Please enjoy using it for free and share your ideas for improvement with us at info@musi-co.com

Not as unique and clever as I thought

All of the genres sound the same, and the sounds definitely sound like an AI put them together - it feels like a random amalgamation of tones and voices, with no sense of direction.
