Why ActivityOS
The only platform built
for independent activity schools
Competition management
Import schedules by photo or PDF, track entries, record results and share medals with parents the instant they're entered. Competition management built in from day one — unlike most booking and membership platforms.
Simple, flat pricing
From £19/month with no per-student fees, no percentage cut of payments, no hidden charges. Free for a full term to get started.
Parent portal included
A full parent-facing app with invoices, timetable, results and push notifications — included at every price point.
UK-first
UK term structures, bank transfer invoicing, GBP, Sage/Xero export and GDPR compliance built in from day one.
Safeguarding built in
DBS expiry tracking, 2FA and GDPR-anchored data retention — most competitors don't touch this at all.
Everything in one place
Built for the way activity schools actually work
Not generic business software. ActivityOS is purpose-built for independent UK activity schools — from your first student to your tenth studio.
Student management
Add students, assign classes, set term rates and track returning vs new enrolments. Everything in one place per student.
Smart invoicing
Generate invoices by term in one tap. Multi-class discounts, week overrides, automatic payment reminders and one-click CSV export.
Visual timetable
Week and day views with studio columns, colour-coded by room. Clash detection built in. Tap any empty slot to add a class instantly.
Parent portal
Every parent gets their own portal to view invoices, pay, see the timetable, competition schedule and results. Add your logo and brand colour — it looks like your studio, not ours. Installs as an app.
Competitions
Track entries, import schedules by photo or PDF, record results and share medals with parents the moment they're entered.
Analytics
Revenue by term, class popularity, medal tallies, top performers. For teachers and parents — know your school at a glance.
Payment tracking
Parents confirm bank transfers in the portal. Teachers confirm receipt. Card payments via Stripe or Direct Debit via GoCardless. One-click Sage & Xero exports, formatted for direct import — no spreadsheet editing required.
Class recommendations
Suggest new classes to parents with a personal message. Set follow-up reminders. Parents can request enrolment directly from their portal.
Multi-teacher logins
Invite teachers by email with module-level permissions. Non-owners only see what they need — settings and billing stay private.
Safeguarding & security
Staff DBS tracking
Track DBS check expiry for every teacher, with automated reminders at 60, 30 and 7 days before renewal is due.
Multi-guardian support
Separated parents, split billing, sibling discounts — every guardian gets their own portal login and notifications.
Two-factor authentication
Secure teacher accounts with authenticator-app 2FA — real protection for the payment and safeguarding data you hold.
Attendance registers
Automatically flag students whose attendance is slipping — before they drop out. Registers take seconds from your phone; everything else happens on its own.
Communication & growth
Two-way messaging
Message a family, a class or the whole school — and they can reply. Send tracked broadcast emails too, so you know who's actually seen your update.
Term renewal automation
Prompt parents to confirm their spot for next term automatically, with a follow-up nudge if they don't respond.
Referral rewards
Parents get a shareable link. When a referral joins, they're automatically credited — no manual tracking.
Free class directory listing
Get discovered by local parents searching for classes — opt-in, free, built into ActivityOS.
Extras
Skill & grading progression
Track each student's grade or skill level and share progress with parents in the portal.
Party & one-off bookings
Take bookings and payment for parties, workshops or trial sessions — outside the regular timetable.
Uniform ordering
Parents order and pay for uniform items directly through their portal.
Push notifications
Notify parents the moment an event is created, cancelled, or a result is entered. Teachers get notified when a payment is confirmed or an enrolment is requested. Straight to their phone — no email needed.
