Your training, in your pocket

  • Term attendance and a calendar of every class
  • Current belt, grading history and grading requests
  • Licence status with renewal reminders
  • Club updates from your sensei
For clubs

Your dojo, organised

Instructors and club officials get the whole club in one place, on a phone at the side of the mat or on a laptop at home.

  • Member records with contact, medical and next of kin
  • Take the register in seconds, class by class
  • Record gradings and licence periods
  • Create events and see sign-ups and grading requests
  • Post announcements to the whole club
Why clubs choose Seijitsu

Made for the way martial arts clubs actually work

Grading, understood

Kyu and dan grades, coloured and striped belts, grading days and requests to grade. Not a generic "membership level".

Registers in seconds

Pick the class, tap present or absent. Attendance flows straight into each member's term statistics.

Licences on time

Track every licence period and remind members before cover lapses, so nobody steps on the mat uninsured.

Safety details to hand

Medical notes and next-of-kin contacts are kept with each member, ready when you need them.

More than one club

Train at two dojos? One account belongs to several clubs and switches between them in a tap.

One place for news

Course dates, closures and seminar details go straight to members instead of getting lost in group chats.

  • Designed around real club nights, gradings and courses
  • Respectful of tradition: grades, belts and etiquette done properly
  • Simple enough to use between bows
