Celsius Attendance vs Learn Claude (Cert Exam Prep)

Celsius is the attendance system built for school clubs and teams. Tap in and out using your phone's NFC or a physical tap card at the team reader — no sign-up sheets, no manual tracking. How it works: Walk in, tap the wall reader with your phone or card, and you're checked in. Tap again when you leave. That's it. See who's here: The live "Who's Here" view shows every member currently in the shop, updated in real time. Track your hours: Your personal dashboard shows your recent activity and total hours logged, so you always know where you stand. For team leads and mentors: Admins get a full management dashboard to view attendance across the team, register new NFC cards, run manual check-ins, and generate reports.
