Torc

Torc is a local-first toolkit for reverse engineering health wearables and building weird/fun things on top of the raw data.

Right now the first target is the Oura Ring 4, because that is what I have. The bigger idea is not "open source Oura", and not just rings either.

The point is to build a clean core for:

• protocol work
• raw-data access
• sync / decode tooling
• my own ML models and derived metrics
• strange and fun interfaces on top

Goals

• understand how the device actually talks
• pull data locally and work from first principles
• make my own metrics instead of stopping at the vendor app
• build playful interfaces, not just another dashboard
• keep the code small, legible, and fast to iterate on

Docs

• docs/charter.md: for AI agents
• docs/protocol.md: current protocol reference
• docs/findings.md: short confirmed findings and open questions

Notes

• Prior community reverse engineering work, especially ringverse, helped establish a useful baseline.
