Booking · POS · Staff CRM

Your studio's own app. Without building one.

Caldekins is the booking app, point of sale and staff CRM behind independent spas, gyms and yoga studios. One app, your brand inside it — clients scan your QR code and only ever see your studio. Live in days, not months.

We move your clients and data over for you.

One platform, re-skinned per business — tap a brand to see it change.

The platform

Everything your front desk does, in one place

Built alongside a working spa, so it covers the day as it actually happens — bookings, payments, staff and the numbers.

Client booking app

Your clients book sessions, classes and treatments in your own branded space in the Caldekins app — your logo, your colours, your services.

£

Point of sale

Take payments at the front desk with tap to pay, sell retail and gift cards, and keep every sale in one ledger.

Staff CRM & scheduling

Rotas, client notes, visit history and day sheets — everything your team needs to run the floor.

Memberships & packages

Recurring memberships, class packs and credits that renew, pause and redeem themselves automatically.

Reporting

Revenue, attendance and utilisation at a glance, so you know what's working without exporting a thing.

Your brand everywhere

Clients scan your QR code and land straight in your studio. Inside the app they only ever see your business — logo, colours, receipts and emails.

Beyond the spa

Built for your kind of venue

One platform, tuned per business — the vocabulary, features and customer experience change with what you run.

Switching is our job, not yours

We take over your existing system

Moving platforms is the reason most studios stay stuck. So we do it for you: clients, memberships, visit history and upcoming bookings come across intact, at no extra cost — and nothing goes live until you've checked it.

1

Show us your current setup

Mindbody, Fresha, Glofox, TeamUp or spreadsheets — send us a login or an export and we take it from there.

2

We migrate everything

Clients, memberships, packages, visit history and upcoming bookings, checked line by line before launch.

3

Go live under your brand

Your branded space goes live in the Caldekins app — no App Store wait — your team gets the CRM, and your clients never notice the switch.

See it wearing your brand

Build your app in sixty seconds — no card, no commitment, free migration when you switch.
