Attendance Check - Roll Call

No paper sheets, no roll call. The teacher starts a check-in and students just hold their phone close. The attendance table builds itself, date by date.

Record attendance for your classes just by holding phones close.

No roll call, no paper attendance sheets, no QR codes to scan. The teacher starts a check-in, and each student simply holds their phone close and taps "Yes". Who attended and when is recorded automatically, and an attendance table with dates across the top builds itself.

■ The teacher only does two things • Register the course name (and groups, if the same course is taught to several classes) • Before class, pick the course and tap Start

There is no need to register dates or weekdays. Every day you run a check-in simply becomes a new column in the table.

■ Main features • Check in by getting close: the student holds their phone near yours and taps "Yes" • Automatic late detection: set a grace period per course, and check-ins past it are shown in red • Attendance table by date: students in rows, dates in columns. Present (○), Late (L) and Absent (−) at a glance • Groups: teaching the same course to several classes gives each class its own table • Per-student records: see the exact date and time of every check-in • Student history: students keep a record of the classes they attended on their own device

■ What the student does • Enter name, student ID and email once • Before class, open "Check In" and tap "Yes" on the course that appears

■ Communication and data Check-ins travel directly between devices over Bluetooth and never pass through a server. Records stay on each device. No account is required.

■ Before you start • Bluetooth is used to run and register check-ins • The teacher's device keeps accepting check-ins even while the screen is locked • Students can check in from within the same room as the teacher's device (roughly 5-15 m indoors) • Real check-ins need a device for the teacher and one for each student
