Software for CrossFit boxes and functional training
Kaizer for Gyms is software for CrossFit and functional boxes that brings together a class schedule with capacity and fixed spots, AI programming, QR check-in, dues tracking and an app with your box's brand. It costs from USD 49 a month for up to 50 members, and you can try it free for 14 days.

What Kaizer organizes in a box
What lives today between a spreadsheet of time slots, the WhatsApp group and the whiteboard, in one place.
- 01
The class schedule, set up once
Each class is an activity type with its color, duration and capacity, and each schedule generates the sessions for the coming weeks on its own. If Tuesday is a holiday, you delete that session and the rest of the series stays as it is.
- 02
Regulars with a fixed spot
The member who comes Monday, Wednesday and Friday at 7:00 is booked into every future session of that schedule, without signing up each time. Each fixed spot takes one place of the capacity.
- 03
Bookings from the app and attendance
Members book and cancel from the app. When class ends, the coach marks them present or absent, and attendance stays in each member's history.
- 04
Programming, written in Kaizer
Routines with circuits and supersets, every set logged with RIR or RPE, and loads that adjust as the member trains. The gym-floor programs you publish are visible to the whole box in the app.
- 05
QR check-in at the door
The front desk scans the QR code in the member's app, which expires and renews on its own, and the same screen shows the classes they booked that day so you can mark them present.
- 06
Dues up to date
You set up the box's memberships with their amount and frequency, record each payment and send a reminder to members who fall behind. You keep collecting the money the way you do today.

How you get your box started
- Step 01
Register the box
Add the name, logo and colors, and get 14 days free, no card.
- Step 02
Build the weekly schedule
Create the class types and their schedules, add members with fixed spots and, if you open the floor for free training, add open-gym slots with an hourly capacity.
- Step 03
Add coaches and members
Coaches join with their role. Members join with the box's invite link or the QR code printed at the front desk.
- Step 04
Publish the programming
Upload the month's program as a gym-floor program or build routines per member, by hand or with Kaizer's AI using the box's exercise catalog.

What you see about your box at month end
- 01
Occupancy by class and schedule
Which classes fill the floor and which active schedules stay under 30% occupancy in at least three classes, so you can decide what to move.
- 02
No-shows and late cancellations
Bookings marked absent and cancellations made less than 2 hours ahead, by activity and by coach.
- 03
At-risk members
Who stopped training, stopped coming through the door or lost their streak, so you can call them before they cancel.
- 04
Downloadable reports
Attendance and occupancy by class, joins and cancellations, at-risk members, expiring medical clearances, staff performance and an executive summary.
When another tool is a better fit
- Kaizer does not process payments: if your box needs to charge cards inside the software or run a point of sale, look for one with built-in payments.
- It has no WOD leaderboard for members to compete with each other. If that is central to your box, Wodify publishes leaderboards with Wodify Perform.
- It does not issue tax invoices or connect to your country's tax authority.
