Everything you need to stay above the line
From today’s lectures to semester predictions — built for students who can’t afford to guess.
Know your bunk budget
Live predictions show how many classes you can still miss, or how many you must attend, to hit your target.
Subjects without limits
Add any number of subjects with personal minimums, previous lecture counts, and full attendance history.
Timetable that drives Home
Mon–Sun slots with optional classroom and teacher. Today’s list on Home comes straight from your schedule.
Calendar & analytics
Month dots for marked days, overall rings, present vs absent, and subject bars against each target.
Share setup, not history
QR-share subjects, timetable, and minimum %. Attendance records never leave with the code.
Stay safe with math, not guesswork
Percentages are computed from your records — never stored as a guess. Set a target from 50–100% (default 75%) per subject or overall.
