Run your school,
not your software.
Kihon is a modern management system for martial arts schools, yoga studios, and gyms. Members, billing, attendance, and rank tracking that just work, on the web, on Mac and iPad, and up on your lobby TV.
Kihon means "the fundamentals" in martial arts. After years inside a multi-location school and watching the existing software fail at the basics, I'm building the one I always wished existed: fast, honest, and great on the devices schools actually use.

What school owners say about the software they pay for today
Billing you can't trust
Double charges, missed charges, and members billed after they cancel. Owners end up auditing their own billing system every month.
Hidden fees and lock-in
Unpublished pricing, required add-ons, rising processing fees, and year-long contracts you can't leave even when the product fails you.
Apps stuck in 2010
Dated, spreadsheet-like interfaces with settings scattered everywhere. Mobile apps that crash, or don't exist at all, while your front desk runs on an iPad.
Families as an afterthought
Parents forced to register each child separately, with separate payments and no way to see the whole family's ranks and attendance in one place.
Belt cycles done by hand
No attendance-based promotion eligibility, no bulk promotions, no testing events. Owners track rank progress in spreadsheets next to the software that should do it.
No proof when it counts
A parent disputes a charge or claims they never signed, and you have nothing to show for it. Chargebacks you should win, lost for lack of a record.
How Kihon Fixes It
The fundamentals, done right
Billing you can prove
Real drawn signatures with validation (a dot or empty box is rejected), an evidence record frozen with every contract, and a one-click dispute packet that bundles the signed agreement, attendance log, and payments to win chargebacks.
Honest pricing
Published prices, month-to-month, cancel anytime in one click. No setup fees, no required add-ons, no surprises on your statement.
See problems coming
A term-aware revenue forecast that shows which month your committed revenue rolls off into month-to-month, so renewal storms are flagged months ahead instead of after they hit.
Native where it counts
Real Mac and iPad apps built with Swift, plus a full web app and lobby displays for any TV. A front-desk iPad check-in kiosk that keeps working even when the Wi-Fi doesn't.
Family-first accounts
One household, one payment method, one registration flow. Every child's rank, attendance, and schedule in a single view, with split payments handled cleanly.
Belt cycles built in
Attendance-driven promotion eligibility, bulk promotions, and testing events with registration. For yoga and gyms: class packs and memberships handled just as cleanly.
Fast and reliable
Instant search, instant check-in, no spinners between you and your members. Built to stay up during the 6 PM rush.
Support from the builders
Early schools work directly with the team building Kihon. Your feedback shapes the roadmap, and your questions get answered by the people who write the code.
