ActivityOS

ActivityOS is the all-in-one management platform built for independent UK activity schools — dance, gymnastics, martial arts, music, drama and sports clubs.
Run your entire school from one place, and give parents a portal of their own.
For teachers and school owners:
— Generate and send invoices per student, per term, with automatic multi-class discounts
— Set up billing automation so invoices go out and reminders chase overdue payments without you lifting a finger
— Manage your timetable with a clash-checked week and day view across all your studios
— Track festival and competition entries, results and medals — even import entries straight from a PDF or photo
— Recommend classes to parents and follow up automatically
— Create events with push notifications and RSVP tracking
— Invite other teachers with module-level permissions
— See revenue, student counts and class popularity at a glance
— Keep allergy, medical and emergency contact info on file for every student
For parents:
— View and pay invoices, including secure online payment
— See your child's full timetable and request to join new classes
— Check festival entries, schedules and results
— RSVP to school events
— Track fees paid and classes enrolled
ActivityOS was built specifically for independent UK activity schools — not adapted from generic business software. No per-student fees, no hidden charges: just a flat monthly price.
Your data stays secure with bank-level encryption, UK GDPR compliance, and two-factor authentication for teacher accounts.
