Stillness app UI

About the project

Stillness is built around one idea: the calmest interface is barely there. Sessions fade the UI away and lean on spatial audio — mixed with AVFoundation — so guidance feels like it comes from inside the room.

The Apple Watch companion runs haptic-guided breathing sessions completely offline, and CloudKit sync keeps progress seamless across devices. Apple featured the app in "Apps We Love".
