QR, PIN or front desk — every entrance covered.
Each member carries a personal QR code in their app. No phone? They tap a PIN at the kiosk. Forgot both? Your front desk checks them in manually with one click — every entry logged with method, time and zone.
- Personal QR codes rendered in the member app, validated in real time
- PIN entry for kiosks and members without their phone
- Manual override with staff attribution for full accountability

Know how full every zone is — right now.
The occupancy heatmap shows live headcounts per zone at every location: weights, cardio, studios, pool. Spot crowding before members complain, staff peak hours intelligently, and share busy-times with members in their app.
- Per-zone live counts with configurable capacity limits
- Hourly heatmap revealing your true peak patterns
- Multi-location view to compare utilization across sites
The door enforces your rules, so staff don't have to.
Frozen membership? Denied at the door — automatically, while the member keeps app access. Plan only covers off-peak hours? Access windows enforce it. Zone not included in their plan? The scan says so. Awkward conversations, eliminated.
- Freeze-aware — frozen members are blocked at check-in but keep their app
- Access windows by plan — off-peak, weekday or full access
- Zone permissions per plan, per location
