About this app

Still tracking who paid and who has sessions left in a notebook or a spreadsheet? Attendlr is the trainer's app: students, attendance, passes, payments and stats in one place. Start free, and know it, don't guess it.

BUILT BY A TRAINER, FOR TRAINERS

Attendlr was built by a trainer who managed a group-class roster of 1,600+ students on paper, then in Excel, and still couldn't answer four basic questions:

✓ Who still has sessions left on their pass?
✓ How much am I actually making?
✓ Who was at training three weeks ago?
✓ What are my expenses?

Attendlr answers them.

WHAT THE APP DOES

✓ Student records: contact details, notes, automatic archiving
✓ Sessions and attendance: a few taps during class, searchable history
✓ Passes: attendance counts sessions down automatically, debts become visible
✓ Payment recording: you keep the ledger, the app does the math
✓ Your clients don't install anything: the app is yours, the data is yours

FREE PLAN, NOT A TRIAL

The full core workflow is free with no time limit: 10 students, 20 sessions per month, 2 class types, 1 location. As long as that's enough, you pay nothing. When you outgrow it, three paid plans:

BASIC: remove the limits
✓ Unlimited students, sessions, class types and locations
✓ Class reminders, daily agenda, notification inbox

PRO: run it like a business
✓ Stats and charts, expense tracking and profit
✓ Owed and prepaid client lists
✓ Payment types and detailed pass management
✓ Leads, tags, favorites, month calendar
✓ Birthday and client drop-off alerts

PREMIUM: the full package
✓ Product catalog and sales tracking
✓ Advanced reports and shareable PDF summary
✓ CSV export and import
✓ Activity heatmap, adjustable time windows
✓ Priority in-app chat support
