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.

Get the answer for your own studio
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.
Per day
From sitting down to leaving
A typical day, not your best day
How full you are
43%
Empty seats cost you
$4,248 / day
That is $127,440 a month, over 30 days.
Turns per seat
6.7
Maximum daily sales
$7,448
Your daily sales
$3,200
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.
