Fitness studio software

Studio software, set up for you

Strong OS is fitness studio software for boutique studios that run a timetable of classes. It runs your timetable, online booking, waitlists, memberships, class packs, payments and check-in, with a booking page and member app your members use to book.

The difference is the setup. A real person moves your members and their remaining credits across, builds your timetable, memberships and packs with you, and gets you live. Afterwards you talk to a person, not a ticket queue.
