Everything between the class and the payment.
fit8 handles the admin that comes after teaching — so your evenings stay yours and every class you teach gets paid.
Never miss a class
Regular classes plan themselves, and each one gets confirmed — by you in one tap, or automatically at the gym.
Get paid on time
Every gym gets a correct invoice on the 1st, built from what you actually taught.
Always covered
Can’t make it? Ask colleagues in a tap, and the gym is told who’s coming.
Know your numbers
See what you earned per gym this month, what’s paid and what’s still open.

Your class, on the Lock Screen.
While you teach, the class runs on your Lock Screen and in the Dynamic Island — time left, progress, and a “Taught it” button the moment it ends.
- Starts on its own, even with the app closed
- Confirm with one tap when the class is over
- On Android, a reminder after class does the same
Invoices that look like your business.
Pick a layout and an accent colour, add your logo, and write your own intro and payment terms in each language. The PDF updates as you go.
- Three layouts, six print-safe colours, your logo
- Choose and order the columns on every line
- Bank details and tax number in the footer
Know what you’ve earned — and what’s still open.
This month per gym and the last six months at a glance — what’s paid, what’s outstanding, and a nudge when an invoice is overdue.
- Outstanding and overdue amounts on one screen
- Small-business VAT exemption supported
- Invoices in English, German or French, independent of the app language
