Sign-ups, billing, access, workouts, in the palm of your hand.Recurring plans and billing, turnstile, classes, member app and Wellhub and TotalPass payouts in one system. AI works inside the operation, and a team stays with your management.Members decide in the first three months.

63% of new members left before the third month, at a gym in Rio (Sperandei et al., 2016)

4% stayed more than 12 months in a row at the same gym (Sperandei et al., 2016)

62.7K active gyms and fitness centers in Brazil (Panorama Setorial Fitness Brasil, 2025)

R$ 9.90 per aggregator check-in at a gym chain, capped at the walk-in plan price (Seu Dinheiro, 2026)

The system shows the member. The cash is scattered.Classes in one system, Wellhub and TotalPass check-ins in another portal, declined cards at the gateway and the broken machine in a WhatsApp group. At month-end, someone pulls it all together by hand.You lose control.Each system handles its own piece. Lost revenue falls between them: the declined monthly fee, the unpaid visit, the member who stopped coming.

Declined monthly fee: The card is declined, the charge rolls to next month, and the member leaves without canceling.

Aggregator: The per-visit payout varies by plan and is capped. Without reconciling, no one sees the visit now worth zero.

Missing member: The system flags that the member stopped coming, and no one owns the call.

Machine down: The treadmill breaks, the notice sits in WhatsApp, and the machine spends the week with a paper sign.

Every gym workflow, digitized.From sign-up to turnstile, from front desk to month-end close. Every workflow in one system, with the gym's data within reach of whoever decides.

Sign-up and recurring plan: The member picks a plan and pays by card or Pix Automático.

Recurring billing with dunning: The monthly fee is charged on time, and late payers get the approved dunning before it becomes a task.

Turnstile and access control: The Control iD turnstile lets in paid-up members and calls the front desk for the rest.

Classes with capacity and waitlist: Members book in the app; if it's full, they join the waitlist and get the next open spot.

App check-in: The member checks in to class, and attendance goes into their history.

Front desk POS: Supplements, accessories and day passes at one register, with Pix, card and invoice.

Member app with workouts: Today's workout in the app, and the machine's QR opens the exercise video.

Finance and cash: Monthly fees, front desk and payouts in one register, with the daily close checked.

Wellhub and TotalPass reconciled: Check-ins and payout side by side, with the value of each visit.

At-risk member with owner: After fifteen days without training, the member becomes a trainer's task, with a deadline.

Maintenance ticket: The machine's QR opens the ticket, with technician, deadline and machine history.

AI assistant: Ask what an aggregator visit is worth and get the answer from your gym's data.
