Save the technique. Try it on the mat. Keep what works. You spot a slick technique scrolling at night. You hear a coaching detail in class. You figure something out in a roll. By Tuesday it's gone. BJJ Technique Journal is where the ideas land — and where you actually open them before training. WHAT YOU CAN DO • Save a note in seconds: type it, paste a video link, or tap the mic. Voice notes are transcribed on your iPhone, no cloud. • Group by Topic: closed guard, leg locks, escapes, your half-guard game. Topics work the way you think about your jiu-jitsu. • Mark "To Try": flag the 1–3 things you want to test this week. They wait for you on the Notes screen, not buried. • Track what worked: after rolls, mark each attempt: Worked, Almost, Didn't, Skipped. Add a quick reflection. See which techniques are earning a spot in your game. • Get reminded after training: pick your training days and times. The app pings you while the roll is still fresh. • Search everything: find that triangle detail from three months ago by typing "triangle." FOR ANYONE WHO LEARNS FROM CLASS, VIDEOS, AND ROLLS This isn't a session log. It isn't a mat-time tracker. It isn't an instructional library. It's the notebook for the techniques, details, and "things I want to try" that scatter across saved videos, screenshots, and your notes app today. White, blue, purple, brown, black. Gi or nogi. Drilling or rolling. Same notebook. YOUR NOTES STAY ON YOUR PHONE No account. No sign-in. No servers. Your notes live in local storage on your iPhone, and only on your iPhone. If you delete the app, the data goes with it. PREMIUM (OPTIONAL) Free is enough to learn the workflow. Premium unlocks unlimited notes, unlimited voice notes, unlimited videos and links, and full try-history. Yearly with a 7-day free trial, a lifetime option, or month-to-month. — Made for grappling hobbyists who'd rather train than fight their notes app. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
