Attendance you can trust, without stopping class.

6:26Live classroom board
The room updates as students arrive.
Checked-in names appear with timestamps while the board tracks time remaining, progress, and who is still waiting. The session can close automatically.
- — Back-of-room QR and PIN
- — Live roster and countdown

Professor workflow
From roster to term record.
Import a registrar roster, start a timed session, make documented corrections, and export a complete attendance grid when grades are due.
- — Excel and CSV roster import
- — Manual overrides with history
- — CSV, Excel, and shareable reports
Icebreakers
Take the roll, then read the room.
Attach an anonymous one-tap icebreaker or a custom two-to-four-option question to check-in, then reveal the aggregate result to the room.
- — 67 ready-made prompts
- — Custom multiple-choice questions
- — Anonymous aggregate results
Check-in verification
Signals for review, never automatic punishment.
Rotating codes, a classroom-radius check, device correlation, and timing signals help professors review unusual check-ins. Every result is marked Flagged, Review, or Clear.
- — Professor-controlled review
- — Forensic CSV, Excel, and JSON export
- — Location and device collection can be disabled
Rotating code and classroom radius agree
A signal needs professor review
Multiple signals need attention
No check-in is rejected or punished by a verification signal. The professor decides.
Institution view
Turn attendance into action.
Campus roll-ups distinguish students who never attended from those who stopped attending. Built-in email outreach and pulse surveys put the signal to work.
- — At-risk attendance patterns
- — Personalized student email outreach
- — Research-informed retention modelling
Pulse surveys
Ask one campus question in the flow students already use.
An administrator-authored pulse survey appears once across participating check-in screens, with completion rates, confidence intervals, and aggregate results.
- — One response per person
- — Representative or indicative sample label
- — No separate survey link
