RATi Check-In

Published by RATi Open Software Foundation. Hosted at rati.foundation/checkin; source published as rati-osf/tap-away.

A question for the room.
A starting point for discussion.

RATi Check-In lets a host ask a question, share a QR code, and show live group totals. Participants answer with emoji taps on their phones.

  1. Choose a question, up to four topics, and four answers.
  2. Share the join link or QR code with your group.
  3. Compare totals before and after a talk, then copy the totals for a report.

For example, a facilitator can ask how familiar a group is with scams, deepfakes, and sources of help. The answers can guide the discussion.

Check-In stores board text and group totals. Boards expire 90 days after their last use. The host can delete a board at any time.
