A free attendance tool built to keep the math simple
We built this site around one idea: working out your attendance shouldn't take longer than the class itself. No spreadsheets, no sign-ups — just a fast, accurate answer whenever you need one.
Why This Site Exists
Most students have had the same moment: staring at a register, trying to work out in their head whether they've slipped into "shortage" territory before a required minimum kicks in. Teachers and class coordinators go through a version of the same exercise, just across an entire batch instead of one person.
The underlying math is simple — one formula does the job. What's not simple is everything around it: how many classes are still safe to miss, how many you'd need to attend in a row to recover, and what a rule like "minimum attendance" actually works out to in real days. We built this site to answer all of those in one place, without asking for an email address first.
What We Stand For
Free, Always
Every calculator here stays free — no paywall, no "pro" version of basic arithmetic.
Nothing Stored
Your numbers are calculated right in your browser. We don't collect or save your attendance data.
Clear, Not a Black Box
We show the working, not just the result, so you can see exactly how each number was reached.
Who We Built This For
Students keeping an eye on their own numbers against a school or college requirement. Teachers who need a quick answer for one student without opening a spreadsheet. Parents helping a child track theirs. Anyone who just wants an honest, fast number instead of doing the division by hand.
