Built for local business

Free loyalty program and back office for gyms and studios

The Break-even calculator, the Profit by item screen and the Stamp card are free. They are set up for how a studio runs, including how many days a regular can be away before KANJIN flags them.

No card and no time limit. The calculators need no account at all.

How a studio runs

The numbers are set for your trade

A member who misses two weeks is already thinking about cancelling. The habit breaks fast, and the membership fee follows it out the door.

14

days without a visit before KANJIN flags a regular

This is the default for a studio. Writing too early annoys people. Waiting too long means they have already found somewhere else. You can change the number in the back office.

A class has a fixed number of mats. The capacity calculator shows the value of a full timetable, so you can see what the 6 am Tuesday class is really costing you empty.

The maximum assumes every seat is full on every turn, all day. No venue reaches it. For a busy restaurant, 60 to 70% is strong. Use the maximum as a ceiling to measure against, not a target. The gap is usually in the quiet hours.

Questions studio owners ask

How fast does KANJIN flag a member who has stopped coming?
14 days by default, the shortest window of any trade. Habits break quickly in a gym, and a note at two weeks brings people back. At six weeks it is usually too late.
Can I use the stamp card for class check-ins?
Yes. A member gives a phone number at the desk and collects a stamp per class. Ten classes can earn a free one, or whatever reward you set.
Does KANJIN replace my membership software?
No. It sits beside it. KANJIN tracks visits and sends the emails; your billing and contracts stay where they are.
