Free loyalty program and back office for gyms and studios
Two weeks missed, and a member is already thinking about cancelling.
New members buy a class pack full of good plans. Around week 3, the visits start to thin out.
Short answer
Is there a free loyalty app for a gym?
Week 3
The class pack that never gets used up
Week 1 is easy. Week 3 brings a late meeting and a cold, dark morning.
Two missed classes turn into a habit of not going.
Then the pack expires, and the member does not buy another.
Monthly members drift the same way, and cancel when they next see the charge.
14
days, then Slipping away
Fitness habits break fast, so a gym gets the shortest window of any trade: 14 days. After that, a member shows under Slipping away.

What is an empty mat worth?
A class has a fixed number of mats or bikes. Enter spots, classes and price. See what a full timetable earns, and what the 6 am class costs when it runs half 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.
An example
A 12-spot reformer class
A class has 12 spots at $28 each.
It runs 5 times a week with 8 people in it.
That leaves 4 empty spots a class, or 20 a week.
At $28 a spot, that is $560 of unsold capacity each week.
You will not fill every spot. Winning back 3 members who stopped after week 3 is a fairer target.
Stamp card
Stamp each class, reward the streak
10 stamps earn a free class or a guest pass.
Check-in is a phone number at the front desk and one press.
Ten classes for a free one rewards members who keep showing up.
A guest pass also brings a friend through the door to try a class.
What studio owners ask
“We already use membership software.”
Keep it for billing and contracts. KANJIN sits beside it, records visits and lists members who stopped coming.
“Members will not stop to check in.”
Joining is one scan of the poster by the door. After that, check-in is a phone number and one press.
“Will this hold health information?”
No. KANJIN keeps visits, not health data. There is no field for weight, injuries or goals.

Gym and studio questions
- How do I stop new gym members from quitting?
- Notice the gap early. A member who misses 14 days moves into Slipping away on the Stamp card screen. A short, personal note then arrives before the habit is gone.
- Can I use a stamp card for class check-ins?
- Yes. Each class is one stamp. You choose how many stamps fill the card, from 3 to 20, and what it earns.
- Can I email members about a new timetable?
- Yes, once they have said yes to email. The free plan sends one email a month to up to 150 people. Email works in every country.
