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.

Quoi de neuf dans la dernière version ?

FlowLab
- Technique building is now smarter: position and submission pickers default to graph-valid next steps from your current chain.
- Added a toggle so you can switch between suggested next steps and the full catalog.
- Added warnings for unrecognized gaps in a technique chain without blocking saving.
- Technique lists in FlowLab and Vault now open the detail page first instead of jumping straight into editing.
- Added a new technique button directly from the Atlas Techniques browser.
- Fixed technique chain labels so anchors show the actual position/submission names, not step instructions.

Atlas & Learning Content
- Expanded the knowledge graph to 152 positions, 304 perspectives, 126 submissions, 4,790 transitions, and 3,915 position-submission links.
- Added new positions: Cross-Body Ride, Spider Web, Crackhead Control, Hammerlock Control, and Leg Weave.
- Added new submissions: Cravat Crank, Full Nelson, Locoplata, and Short Arm Scissors.
- Improved many existing position and submission entries, including guard, leg-entanglement, choke, crank, and inversion content.

Position & Submission Details
- Position pages now show clearer tactical snapshots: base structure, control target, tactical focus, and weight/pressure cues.
- Added anatomy-style target visuals for positions and submissions.
- Added defensive frame cards so survival structures are easier to scan.
- Clarified opponent threat breakdowns with more honest “why this is dangerous” explanations.
- Cleaned up duplicated dominance/control-depth information on position pages.

Training
