The guest speed check is the fastest way to see a reading — no sign-up, and nothing is stored. Open it from Speed check in the top nav, or go to /guest.
Run it
- Connect device and pick the dyno's serial port — or click Try demo to stream realistic readings with no hardware.
- Watch the live readout: averaged chair speed (big number), left/right roller speeds, the running peak, and the balance gauge. A result box shows — / PASS / FAIL against the current ceiling.
- Follow the prompt: drive forward, pause ~2 s; drive reverse, pause ~2 s.
- Toggle mph / km·h, Reset peak to start over, or expand Calibration constants to tune the reader.
Guest vs. sanctioned
Guest mode never saves anything and you judge pass/fail by eye against whatever ceiling you've set. To record official results tied to athletes and chairs, sign in and use the referee workflow.
