Grapla — BJJ Jiu-Jitsu Journal
iPhone / Sports
Grapla is a BJJ journalling platform and technique encyclopedia for grapplers who want to understand jiu jitsu and expand on their own journey through it.
HUGE KNOWLEDGE LIBRARY.
Browse hundreds of hand-curated positions, techniques, submissions, and movements — all biomechanically connected by thousands of validated transitions. See how positions relate, where submissions live, and how the parts you already know fit into the bigger picture.
LOG YOUR TRAINING.
Record sessions with voice or text. Track coaches, training partners, and gyms. Build a complete picture of your mat time, week after week. Remember everyones names and what you've ever submitted each other with. Our analytics platform is evolving over time, so sessions you log now will have better and better insights as the app grows.
TAKE NAMES.
Are you sick of forgetting peoples names and being afraid to ask them again? Start saving your rolls with them in the app and give them a nickname to help you remember! The app lets you track rolls with everyone you meet while training, and can save all of the positions and submissions you hit in each round, so you can build up insights at a training partner level.
BUILD YOUR VOCAB.
Describe what happened in training — Grapla matches your notes against the library and finds the positions and submissions you were drilling. Curate the matches, name them, save them as your own techniques.
