Rosterr — Canvas check-in

Enter your attendance code once. Rosterr finds your current Canvas class and checks you in.

Rosterr is a small Chrome extension that makes Canvas attendance check-ins painless. Instead of digging through Canvas to find the right aPlus+ Attendance page, just click the Rosterr bubble, type the code your instructor shares, and press Enter. Rosterr uses your class schedule to find the current session, opens the right attendance page, submits your code, and confirms the result — all in a few seconds, so you can get back to the lecture. Confirmed codes are kept briefly on our server so Rosterr works across your devices without re-entering anything. Rosterr never asks for your password, includes no ads or analytics, and only reads the Canvas and attendance pages it needs. Your school's attendance rules and code windows still apply.
