Moves members who cancel
Know who's slipping before they quit.
Members book, check in and log every workout in your app. You see attendance and streaks for each member, so a coach can call the right person this week.
Keep one member and Kaizer pays for itself.
Put in your real numbers. See what keeping members, turning trials into members, collecting late payments and replacing the software you pay for today is worth to your gym in the first year.
Where the money comes from
Each number above has a reason to move.
Kaizer is your own branded app for members, a web dashboard and a staff app for phones and iPads. This is how it changes the numbers you just entered.
Moves trials that join
Trial today. Member tomorrow.
Trial classes book in your app like any other class. Follow every trial from booked to showed up to joined, and see which ones still need a follow-up.
Moves payments you collect
No pay, no entry.
Bookings and check-in pause on their own when a payment is due, so nobody has to chase it at the front desk. Payments run on Stripe.
Moves admin hours and software
Your coaches should coach, not type.
Members log their own training. Check-in works by QR, fingerprint or face. Classes, plans, payments and programs live in one place instead of four tools.
Moves word of mouth
Your app. Not a marketplace.
Your logo and colors on the app your members open every day, and your own App Store listing if you want it. Members never see the studio down the street.
Moves revenue per member
If it has a schedule, it books.
Nutrition consults, personal training and assessments book like a class, so they sell like one. Kaizer also connects to Claude, ChatGPT and Gemini, so you can ask who hasn't come in for two weeks.
From Kaizer's own data
The first months decide who stays.
Real numbers from gyms and coaches already on Kaizer, plus one industry figure for context.
Members who log 8 or more workouts in their first month, about two a week, are four times as likely to still be training in months three and four: 72%, against 18% for those who log one to three.
