Why trainers switch

Stop running your business from your messages

Packs that count themselves down

Sell a block of ten and every booking takes one off automatically. You and your client both see how many are left and when they run out, so nobody is arguing about session eight.

A diary clients book themselves

Put your sessions on the schedule and clients book, cancel and rebook on their phone. No more back and forth to find a time, and no double bookings.

Paid before they turn up

Clients buy a pack, a membership or a single session online. Monthly clients are collected automatically, so you are never chasing a bank transfer.

Everything to run your diary

One place for sessions, packs and clients

1-to-1s, pairs & small groups

Every session has its own length and number of places, so a 1-to-1, a pairs session and a small group of five all sit on one schedule.

Packs, memberships & single sessions

Sell a block of sessions, a monthly membership or a one-off. Set how long a pack stays usable, and credits are tracked per session type, so a 1-to-1 pack covers 1-to-1s.

Payments, handled

Take card and Apple Pay online. Recurring memberships and one-off purchases run themselves, with no invoices to chase.

Fewer no-shows

Automatic reminders before every session, a cancellation window you set, and one-tap check-in so you have a record of who turned up.

A booking experience clients love

Clients book in seconds on the web or in the app. Clean, quick and effortless, so they book the next one.

Know your numbers

Revenue, how full your week is, new clients and who has stopped coming, at a glance.

Questions

The things trainers ask us

I work on my own. Is this too much software?+

No. It works for one trainer with a diary just as well as for a team. You get the schedule, packs, payments and reminders, and none of it needs a front desk to run.

I sell blocks of sessions. Does that work?+

It’s exactly what this is for. Sell a block of five, ten or twenty as one purchase. Every booking takes one off automatically, and you can see at a glance how many each client has left and when the block expires.

Does it write workout plans or track progress?+

No, and we’d rather say so upfront. Strong OS runs the bookings, packs, payments and reminders. It doesn’t build programmes or log lifts, so keep whatever you use for coaching.

How do clients book a time with me?+

You put the sessions you’re offering on your schedule and clients book them on their phone. When someone cancels, the slot is open again for anyone else to take.

We’re a team of trainers. Can each have their own diary?+

Yes. Assign a trainer to every session, and they see their own day instead of everyone’s.

How hard is it to switch?+

Not hard at all, and you’re not the one doing it. We move your clients across with their remaining sessions and expiry dates, build your schedule, memberships and packs, and go live on a day you pick. 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 clients’ data private?+

Completely. Every business is fully isolated. You only ever see your own clients, sessions and bookings.
