Participant Cards​

Each participant is displayed as a card with the following information:

A single participant card showing name, group, data collection buttons, and action icons

Name and Alias​

Each card shows a de-identified identifier (typically starting with "U" followed by random digits). Click the pencil icon next to the name to add or change an alias. Aliases are only visible to the researcher/clinician — not to the participant or in exported data.

Data Collection Status​

Each card has two color-coded buttons — Last Passive and Last Active — that indicate data recency at a glance:

  • Green — Data collected within the last 2 days.
  • Yellow — Data collected within the last week.
  • Red — Data collected within the last month.
  • Gray — No data collected in over 30 days, or none has ever been collected.
