The Sensing.

Four hundred and twelve signals a minute.

The sensor rail sits against the skin and attends. Temperature gradient, micro tremor, pulse interval, conductance, and the small remainder we do not name in marketing materials. Each signal is ordinary. The reading is in the ensemble.

Your readiness is computed against households like yours.

A reading alone is a number. A reading against the pool is a state. Charm compares your ensemble to households of comparable composition, schedule, and history, and returns the only figure that matters: whether you are ready, slightly before you would have said so yourself.

The model is trained on the pool and improves with every wearer. Individual contributions are not itemized. See the Trust Center, which is calm about this.

Fitted once. Adjusted continuously.

The first fourteen days are the fitting period. The ring says nothing; it listens. After fitting, readiness is reported with confidence, and the confidence is warranted, because by then the ring has met every version of you that a fortnight contains.

Refitting is not required after breaks in wear. The ring remembers. It is, structurally, a member of the household.

The ring, in your space.

Rotate it. Then place it in your room at true scale. The ring renders on your own nightstand and reads nothing, yet. Placement is not enrollment. Enrollment is separate, and earlier.
