UnderHooked is the all-in-one Brazilian Jiu-Jitsu training companion. Built by black belts and brown belts who got tired of tracking sessions in Notes and losing their technique notebooks. THE BJJ TRAINING JOURNAL THAT MAKES SENSE Log your sessions in seconds. Capture energy, body, mind, and what worked. Watch your stripes stack up. See your mat hours add up over months and years. Your training, finally documented. WHAT'S INSIDE • Session journal — log gi, no-gi, open mat, drilling, competition. Time, intensity, what you worked, how you felt. • Belt progress — visual ladder from white to black, stripe by stripe. See your real progression, not just a static color. • Technique playbook — your personal library of moves, broken down by position. Add videos, notes, the cues that work for you. • Game plan builder — map your A-game from any position. Visualize your hierarchy. • Competition tracker — log every match, debrief what worked and what didn't, build the reps that compound. • Injury vault — track aches, recoveries, rehab notes. Share with your coach (or keep private). • Achievements + streaks — earn marks for consistency, milestones, technical hits. FOR PARENTS Track your kids' BJJ journey. Add each child as a profile, log their attendance, see their belt promotions, save photos for every stripe. Multiple kids? No problem. FOR GYM MEMBERS If your gym is on UnderHooked, you get every Premium feature for free. Tap in at the gym kiosk to log attendance automatically. Get your gym's Move of the Day. See announcements from your coach. Build community with other members. FOR COACHES UnderHooked includes a coach mode that turns into a gym operations dashboard. Track today's attendance, send announcements, promote members in one tap, post videos to the team feed, see retention reports. Built for the way you actually run your academy. THE DIFFERENCE Most BJJ apps are technique libraries with a sign-up gate. UnderHooked is your training record — yours alone, then shared with your gym if you choose. Your sessions are private. Your injuries are private by default. Your data is yours. PREMIUM UNLOCKS • Unlimited journal entries and technique playbook • Advanced analytics and progress charts • Competition tracker with full match history • Game plan builder • Premium themes and card customization Free for affiliated gym members. Otherwise $4.99/month or $39/year (save 35%). NOT ON UNDERHOOKED YET? Tell your coach. We give every member of an affiliated gym Premium at no cost. OSS!
