How it works.
Roll/Call replaces paper roll and clunky attendance apps with one QR code. Students scan, tap their name, done. Here's everything you need to know.
For teachers
Create your class
Sign in, click New class, and paste your roster. Each line is one student: First Last, or First, Last, StudentID if you want IDs in your export. Set a check-in window duration (default 5 minutes).
Open the window & display the QR
Click Open window when class starts. A countdown begins. Project the QR code on the board or hold it up on your laptop. The live roster below updates as students check in.
Students scan & tap
Students scan the QR with their phone camera, land on a page showing the whole roster, and tap their name. Names already taken are greyed out, so nobody can claim someone else's spot.
Export & clear
When class ends, type a session label (like W1C1) and click Export & clear. You get an Excel file with every student, their ID, and a 1/0 for attendance. Check-ins are cleared so the class is ready for next time. NOTE: Export and Clearing is needed after every class to reset the attendance for next time.
For students
1. Scan the QR with your phone camera. 2. Tap your name from the list. 3. Done — you're marked present.
No account needed. No app to download. Takes about five seconds.
How the safeguards work
Time window. Check-in only works while the window is open. Close the window and no more names can be claimed — students who weren't there can't retroactively mark themselves present.
One name per check-in. Each student can only be marked present once. If someone tries to claim a name that's already taken, the button is greyed out.
One device per check-in. Each phone is tagged so the same device can't check in twice under different names.
FAQ
What if a student's phone is dead? You can manually mark them present from the dashboard before exporting. (Coming soon — for now, note their name and edit the exported spreadsheet.)
Can I change the window duration after creating a class? Yes. On the class page, edit the number under “Window duration” and click Save. Changes apply to the next window you open.
Can I edit my roster later? Not yet — for now, delete the class and create a new one with the updated roster.
What file format is the export? Standard Excel (.xlsx). Opens in Excel, Google Sheets, Numbers — anywhere.
How much does it cost? $10/month AUD. Cancel any time from the dashboard under Manage billing.
