UNDERHOOKED IS HOW YOU FIX THIS
TURN MAT TIME
INTO A SYSTEM.
UnderHooked is a journal, a playbook, a competition tracker, a gym connection, and a trading card you actually want to share — in one app. Built by jiu-jitsu players, for people who train at least three days a week and want their game to compound.
Working on guard retention from back-take attempts. Got passed to knee slice three times in a row — need a frame counter.
01 · TRAINING JOURNAL
IT STARTS WITH THE JOURNAL.
Two minutes after class. Five fields. Done.
Log the session like you'd tell a training partner: gi or no-gi, how you felt, what worked, what didn't. Tag every roll, every submission, every position. Six months from now, you'll know exactly why your guard fell apart in March.
- Gi or no-gi · duration · gym
- Energy in, energy out, body, mind
- Roll-by-roll outcomes + sub direction
- Notes you'll actually re-read
02 · TECHNIQUE PLAYBOOK
YOUR MOVES, MAPPED.
Stop drilling random stuff. Drill what's working.
Catalog every technique you've ever learned. Star the ones that hit. Filter by position. The app cross-references your playbook with your journal — so you see which submissions you actually finish with, in real fights, on real partners.
- 35+ techniques pre-loaded
- A-Game tagging surfaces what lands
- LIVE SIGNAL: hit rate from your roll log
- Position chains — if X, then Y
03 · BELT PROGRESSION
YOUR BELT EARNS ITSELF.
Show up. Log the work. Watch the bar fill.
Every session is XP. Every streak is a milestone. The path from white to black is real and concrete — 4 stripes per belt, 6 degrees of black, every step accounted for. The promotion isn't a surprise. It's earned in public.
- White → Black, full progression
- Streaks, weekly pulse, gym leaderboard
- Belt-adaptive theming — your color, everywhere
- +500 XP for every belt promotion
Trap the arm before they post. Two-step finish.
04 · GYM CONNECTION
YOUR GYM, IN YOUR POCKET.
Coach broadcasts. Move of the day. QR check-ins.
Connect to your home gym in two taps. Watch coach-published technique videos. See who's training, who's catching up. Tap in at the front desk for a quick XP bump and a heartbeat your coach can see. (Your gym not on UnderHooked yet? Send them an invite.)
- Real-time MOTD from your coach
- Gym leaderboard + announcements
- QR tap-in → +25 XP, instant
- Free Premium for gym members
05 · COMPETITION TRACKER
COMPETE WITH INTENT.
Every match. Every method. Every mistake — coachable.
Track every tournament: division, weight, organization, brackets. Log every match with method, time, position. The structured debrief turns a tournament into next week's training plan. Win rate by position. Sub trends. The patterns are there if you have the data.
- Match log + structured debrief
- Win rate by position over time
- Pre-event camp checklist
- Shareable results card
