What Is the SelfSense Server?

The Server is an optional companion to the SelfSense app. The app on its own is enough for one person tracking themselves. The Server is for everything bigger than that — a room with several performers, a workshop with multiple participants, a performance where one body's movement needs to drive sound or feedback for another.

It computes DFA alpha on streams coming from multiple sensors simultaneously and broadcasts the live readings to a shared dashboard.

Two Ways to Use It

Hosted at server.selfsense.me. Open to SelfSense users, no install required. Accepts WebSocket ingest only — the iOS app and other native clients can stream into it from anywhere over the internet. This covers most solo and remote-group use cases.

Self-hosted on your own laptop or LAN server. Required if you need OSC routing into music or visual software, or if you want the Server to talk directly to Movesense sensors over Bluetooth. The source code is available on request to existing SelfSense users — get in touch via the Nodus Labs support portal.

When You'd Want It

• Several people in one room, each with their own sensor stream visible on a shared dashboard.
• A choreographer routing live DFA alpha into a sound or lighting system over OSC.
• A workshop facilitator running ten participants on isolated namespaces from a single laptop.
• A multi-sensor setup on one body (HRV + accelerometer + gait) where everything needs to land in the same view.
