Why wellness studios switch

Stop counting sessions in a spreadsheet

Courses that count themselves down

Sell a course of six sessions and every booking takes one off automatically. You and your client both know exactly how many are left — no paper cards, no spreadsheet, no debate at the desk.

A diary per practitioner

One-to-one treatments, small-group recovery slots and appointments of different lengths on one schedule — with each practitioner seeing their own day rather than the whole studio’s.

A missed 90 minutes really hurts

Automatic reminders before every appointment and a cancellation window you set, so a long slot doesn’t sit empty because someone forgot.

Everything to run the diary

One place for treatments, courses and clients

Appointments & recovery slots

One-to-one treatments and small-group recovery on one schedule, each with its own length, capacity and practitioner. Clients book, rebook and cancel in seconds.

Courses, packs & one-offs

Sell a course of sessions, a pack or a single treatment — and set how long a course stays usable. Sessions are tracked per treatment type, so a massage course covers massage.

Payments, handled

Take card and Apple Pay online, or take payment at the desk with a QR code. Recurring memberships and one-off purchases run themselves — no invoices to chase.

Fewer no-shows, a fuller diary

Automatic reminders, a cancellation window you set, and one-tap check-in so you always know who turned up.

A booking experience clients love

Clients book and rebook in seconds on the web or in the app — clean, quick and effortless, so they come back for the next course.

Know your numbers

Revenue, how full the diary is, new clients and repeat rate at a glance — so you can see which treatments are working and grow with confidence.

Questions

The things wellness studios ask us

We sell courses of sessions — does that work?+

It’s exactly what this is for. Sell a course of six or ten sessions as one purchase; every booking takes one off automatically, and you can see at a glance how many each client has left.

Is this a clinic system?+

No — and we’d rather say so upfront. Strong OS runs the bookings, courses, packs, payments and reminders. It doesn’t keep clinical notes or medical records, so keep whatever you use for those.

Can each practitioner have their own diary?+

Yes. Assign a practitioner to every appointment, and they see their own day instead of the whole studio’s.

Do treatments of different lengths work?+

Yes. Each treatment has its own length and capacity, so a 30-minute recovery slot and a 90-minute deep-tissue appointment sit happily on the same schedule.

Can clients book on their phone?+

Yes — clients book, rebook and cancel in seconds, on the web or in the app.

How hard is it to switch?+

Not hard at all. We move your clients, their remaining sessions and your schedule across and set you up personally, so you’re never starting from a blank page.

What happens if I need help?+

You get hands-on onboarding and a real person who answers — not a ticket queue and a help centre.

Is my studio’s data private?+

Completely. Every studio is fully isolated — you only ever see your own clients, appointments and bookings.
