Holon

Holon is an auditive mixed reality app that generates functional music from your body movements and the world around you - your behaviour. Use it for active commuting - or almost any sport you can think of - Holon adapts seamlessly to your activity and context.

Holon couples movement with sound in an immersive, physical experience that supports and encourages movement in different ways.

Functional feedback can improve concentration, endurance and performance, for example when walking or running. It can also be used for relaxation, meditation, yoga, dance or anything involving motion.

Your fluctuating heart rate and step rate changes the tempo of the music, while other musical content is generated in real time from your activity, course, weather, time of day, health data, and many other signals.

For complete functional biofeedback, we currently support Apple Watch and Suunto Movesense (available as In-App Purchases). Sync your heart rate with professional music apps using Ableton Link!

Holon is based on principles of affective design and biomusicology and puts the user in the centre of an open world of synthesised sound. Holon is a passive, zero-UI app, where your biomechanical movement and biosignals form the musical circuitry. Become part of the circuit, become sound!

P.S. Our professional editor for motion, location, and biosignal-based audio, Holon.ist, launches soon. We made Holon with the same engine - what will you make?

*** Known Issues ***
- Holon sometimes crashes when paused, and in background mode.
- Using Holon in a moving vehicle sometimes causes audio feedback. Deleting and reinstalling Holon should resolve this.
- Apple Watch reconnection problems may occur, either showing an “X” icon on a red circle, or is in a paused state (square icon). Closing and reopening the app on the iPhone - sometimes repeatedly - should improve the connection.
