Class schedule and booking for your gym
Kaizer for Gyms builds your schedule of classes and open-gym slots with capacity limits, and members book from the app with your brand. Regulars get booked automatically, coaches take attendance with Present and Absent, and you see occupancy for every time slot. Included from USD 49 a month.

How the schedule is built
Three layers, from general to specific, so you set up each class only once.
- 01
Activity types
The template for each class, such as Yoga, CrossFit or Functional, with its color, length and default capacity.
- 02
Recurring schedules
You set the days, time, coach and capacity once, and the schedule generates the sessions for the coming weeks on its own.
- 03
Sessions
Each concrete class on the calendar: the one members book and where attendance is taken. You can also create one-off sessions, like a masterclass or a trial class.
- 04
Open-gym slots
Time to train freely, with no coach. With Split into slots, a 7:00 to 13:00 range becomes one-hour blocks, each with its own capacity, to control how many people are on the floor.

Schedules with capacity, booking from the app, fixed spots and attendance.
What members do from the app
- 01
See the gym's calendar
The gym's classes and open-gym slots, in the app with your brand.
- 02
Book and cancel
If the session is open for booking, they sign up on their own and cancel whenever they want. If it is full, the app tells them there is no room.
- 03
Hear about changes
If a session they booked is cancelled or moved, they get a notification.
- 04
Check their history
Their upcoming and past bookings, with the attendance staff recorded.
Tools for your staff
| What | What it is for |
|---|---|
| Capacity | From 1 to 200 spots per session. Without a cap, the session is open to all. |
| Fixed spots | Regulars are booked into every future session of their schedule, without signing up each time. |
| Gym-only sessions | You turn off booking from the app and add members yourself from the panel. |
| Attendance | Present or Absent on each booking. Any staff member can take it, including from the calendar. |
| Pausing a schedule | Future sessions are cancelled and members are notified. When you resume, regulars are booked again. |
| Occupancy metrics | Occupancy, no-shows and late cancellations, by activity and by coach. |

What it does not do
- There is no waitlist: if a class is full, members try again when someone cancels.
- There is no cancellation deadline: members cancel their booking whenever they want, with no penalty.
- It does not charge for a class at booking: dues are tracked in Payments, and you collect the money through your usual channels.
Frequently asked questions
Do members book from an app?
Yes. They book from the Kaizer app with your gym's brand, on iOS and Android. Capacity is always respected, whether the booking comes from the app or the panel.
Is there a waitlist?
Not yet. When a class fills up, the app says there is no room and the member can try again if someone cancels.
How do I handle members who always come to the same class?
Give them a fixed spot in that schedule. They are booked into every future session, including the ones the schedule keeps generating.
Who can take attendance?
Any staff member. The coach opens the session, goes to Bookings and marks Present or Absent when class ends.
Does it work for an open gym floor with hourly capacity?
Yes. You create an open-gym slot, split it into blocks of the length you want, and each block gets its own capacity.
