Observe the mission day.
Describe, then confirm.
A brief daily self-report is recorded alongside standardised wearable observations, which are checked for completeness. When enough valid mission days exist, the participant sees a neutral comparison with their own earlier mission observations.

Two-minute check-in
Rate how today feels and record only relevant mission context. These responses are stored as participant context; they do not currently determine or modify the wearable comparison. This demo does not send a message to the crew or study team.

Illustrative data-check rule for this fictional device: sleep duration, resting heart rate and activity must each have a correctly dated, complete observation from the same source. HRV is optional. Passing this check does not establish measurement accuracy. The final rule needs the chosen device, PI and ethics review.
Compared with earlier valid mission days
Reference: valid observations from 2027-02-01 to 2027-02-03. The table shows today's values and the median of all available earlier valid mission days. It does not indicate risk or prescribe a response.
Included days: 2027-02-01, 2027-02-02, 2027-02-03. Excluded days: none. Optional unavailable observations are omitted without imputation.
Does this comparison fit with what you noticed today?
Your answer records whether the neutral comparison fits your experience. It does not validate the device data or approve a recommended action.
