It's not just for school subjects: if you teach, coach or run sessions and collect fees, ClassJar is for you.

ClassJar keeps every student, member or player, their fees and their attendance in one place — and writes the polite WhatsApp reminder for you to send in one tap, from your own number. The wording adapts to what you run (students, learners, members, players).

What you can do
• See who has paid and who is pending for the month, at a glance
• Mark attendance in seconds — and let parents or members know when someone is absent
• Snap a photo of your paper register and it reads the names, numbers and fees for you
• Send fee and attendance reminders on WhatsApp — from your own number, no per-message charge
• Share a clean public page and get discovered by new students or members
• One app for every kind of class — the labels change to fit tuition, music, dance, yoga, sports and more

Why teachers, coaches & instructors love it
No more chasing fees from memory, no more attendance scattered across notebooks and chat groups. Set up in minutes. Free to start.
