## What is Jiu Jitsu Reference?

Jiu Jitsu Reference helps you log live training moments, track what you land, miss, and concede, and review your personal jiu-jitsu knowledge over time.

Create logs quickly, connect them to training partners and knowledge nodes, and use the app to spot what is working, what is slipping, and what needs study next.
