Now in beta · iPhone + Apple Watch

Music thatmoveswith you.

Your body becomes the input.

SonicStride listens to how you move — and the music responds.

Free during beta · iPhone + Apple Watch required

We're constantly distracted.
Music should help you go inward — not pull you further out.

How it works

Your body streams live

Apple Watch sends heart rate, motion, and physiological signals to SonicStride every second.

Music composes itself

As your state changes, the soundscape reshapes — intensity, rhythm, texture — automatically.

Your session becomes a record

Each run is saved as a musical journal — a record of your body in motion.

Your body.
The DJ.

No playlists. No decisions.
Just move — the music follows.

Working out feels so different now. The music matches my pace perfectly, whether I'm running or taking it slow, and it keeps me pumped. The tracks are super fresh — feels like I've got my own DJ.

I didn't realize how much I keep checking my phone during runs until I used this. I just… stopped. The music kept changing and I forgot about everything else.

I don't really know how to describe it… but it felt kind of magical.
