Martial arts gym management software that runs on your belt system
Most gym software models a fitness club: memberships, check-ins, a class calendar. A martial arts school runs on rank. Kmura treats the belt system as the data model — and lets you define what those belts are.
Built Around Ranks, Not Machines
The difference between software written for a gym floor and software written for a mat.
Your belt catalog, not ours
The ranks themselves are data you control. Define the belts your art actually awards, in your order, with your names — coloured belts, kyu and dan grades, sashes, degrees. Nothing in the system assumes a particular ladder, so a school that awards ten ranks and a school that awards five both describe themselves accurately instead of picking the closest preset.
Promotion logic you configure
Time in grade, attendance requirements and stripe or degree increments are settings, not assumptions. Set what a promotion requires at each rank and the system tracks who is approaching it, so instructors get a list to review rather than a spreadsheet to reconstruct from memory.
Curriculum tied to rank
Techniques and syllabus are fully customizable and attach to the ranks you defined, so what is taught in class connects to who has actually been shown it. Attendance is not just a headcount — it rolls up into progression, which is the part generic gym software leaves as a note field.
Where Kmura comes from, stated plainly: it is built BJJ-first, and Brazilian Jiu-Jitsu academies are our core focus.
That is not a limitation so much as a starting point. Everything that makes it work for jiu-jitsu — the belt catalog, stripes, promotion logic, curriculum, attendance — is configurable rather than hard-coded, so a karate, judo, taekwondo or muay thai school with a graded ranking system can describe its own progression accurately. What you inherit is defaults shaped by jiu-jitsu, which you change once during setup.
One Price, and the Rate That Actually Costs You
For most schools the subscription is not the biggest software line — the percentage taken off every payment is.
Kmura is $150 a month per location, flat. Every feature is included at every size: there are no per-student tiers, no feature gates and no add-on line for the things a school actually needs. A school of thirty and a school of three hundred pay the same monthly price.
Card processing is 2.6% + 30¢ per transaction, built in — memberships, drop-ins and merchandise all run through it, and funds land in your own bank account. The only thing billed outside the flat price is SMS, which is pay-as-you-go with the cost shown before you send.
Instructor hours and classes taught are tracked as well, which makes paying your staff a matter of reading a report rather than reconstructing a month — though tracking is where it stops: Kmura is not payroll software. The pricing page has the full breakdown.
A Nightly Review That Drafts, Never Sends
The students who leave rarely announce it. They just stop showing up, and by the time anyone notices it has been a month.
Every night Kmura reads your school's activity — attendance patterns, gaps, time in grade, billing state — and surfaces what a person would have to go looking for: who is drifting, who is due for a promotion, which leads have gone cold.
For each one it pre-drafts the follow-up message. Your staff read it, edit it if they want, and send it. Kmura never sends anything on its own.
That distinction matters in a martial arts school more than in most businesses. The message that brings a student back is a personal one from their instructor, and it stops working the moment it reads like it came from a system.
English and Brazilian Portuguese, Throughout
Not a translated marketing site with an English product behind it.
The whole platform ships in both languages: the owner dashboard, the staff tools and the student portal. Switching is one click, and it is per person — a Brazilian head instructor can work in Portuguese while the front desk works in English, in the same school, on the same data.
For a martial art with a Brazilian lineage that is not a nicety. The people teaching in a lot of these schools think about the art in Portuguese, and asking them to run the business in a second language is a tax nobody should be paying.
