Grade progression made readable
The judo federation is one of France's largest (~600,000 members). White-to-black progression is the heart of the practice — your profile records it as the spine, not a footnote.
Kelenz for your sport
Kelenz for Judo
From white to black belt: your judogi tells your story — so does your profile.
“From white belt to black, your judogi tells a story — your profile too. Grade progression at the heart, not in the footer.”
Why Kelenz for judo
5 official stats configured
Combats, wins, losses, ippons, medals: the standard grid is handled natively, by season.
From dojo to international — one tool
Every judoka and sensei gets an indexed public page — senior, U19 junior, veterans, women's. Achievements and results followed by the community (fights, competitions, grade tests).
The dojo culture respected
Judo isn't a fighter marketplace. It's a dojo, a sensei, uchi-komi partners. Kelenz reflects that community.
