A location-based attendance app that trusts, then verifies
Pair the rotating QR with an optional GPS check. Students can only register a scan when their device is actually on-site.

Geofenced check-ins
Each class or location has a coordinate + radius. Scans outside the geofence don't count.
Per-session opt-in
Turn GPS on for labs and exams; leave it off for hybrid lectures. Your call, per session.
Privacy-respecting
Location is checked once at scan time — we don't track students between scans, and the raw coordinate isn't stored.
Fallback when GPS is off
If a student has location off, they see a clear prompt. No silent failures.
Frequently asked questions
How accurate is the location check?+
Modern phones report GPS to within 5–15 meters outdoors, and ~30 meters indoors with Wi-Fi assist. We let you set a radius per location, typically 50–100 m.
What happens if a student's phone GPS is inaccurate?+
The student sees a clear error and can ask the instructor to mark them present manually, or file an amendment with a note afterwards. No silent drops.
Does this work indoors?+
Yes — phones combine GPS with Wi-Fi and cellular tower signals indoors. In concrete-heavy buildings we recommend a wider radius.
Is the raw location stored?+
No. We check the coordinate against the class's geofence at scan time and store only the result (inside / outside / unavailable).
