Kelenz for your sport

Kelenz for Brazilian Jiu-jitsu

Why Kelenz for BJJ

Grade progression at the core

BJJ has a strict belt grid (white → black, plus stripes). Kelenz writes it into the career history — a rank stays with you, regardless of the academy.

5 official stats configured

Matches, wins, losses, submissions, medals: the standard grid is handled natively.

Gi and No-Gi distinct

2 specialties: Gi practitioner, No-Gi practitioner — multi-specialty welcomed.

The academy respected

BJJ lives in an academy under a professor. Kelenz reflects that lineage — your profile carries the line, not an anonymous club.

What Kelenz changes for each profile

From the U19 purple belt prepping brown to the head professor of an IBJJF academy — here's what Kelenz delivers for BJJ.
