AI reads and analyzes
After every training session, get an AI-generated breakdown of what happened on the mat. It connects the dots across your sessions and spots trends you might miss.
Real-time AI feedback on every session with actionable suggestions
Log your rounds, submissions, and taps as they happen — not hours later from memory. Built-in timers, one-tap stat tracking, and lock screen controls make it easy to capture everything between rounds.
Start the timer when you step on the mat. It runs in the background while you roll, and audio cues let you know when rounds start and end — so you never have to check your phone mid-roll.
Round timer with real-time session stats
When the round ends, grab your water and tap a few buttons. Increment your submissions, log a tap, tag the triangle you hit — it takes seconds, and you'll never forget the details.
Increment stats and tag techniques between rounds
When you're done rolling, everything you tracked is already filled in. Add your notes while the session is still fresh, then save — no more trying to reconstruct your rolls from memory at home.
Save your session with class notes and reflections
Don't want to unlock your phone between rounds? You don't have to. Increment your stats right from the lock screen or Dynamic Island — your phone never leaves your bag.
Track rounds from your lock screen
Browse 150+ built-in techniques, create your own, link instructional content, and track every time you use a technique in training.
Start with a comprehensive library organized by category — from sweeps and guard passes to chokes, joint locks, and takedowns. Filter by category, search by name, or view your custom techniques in one place.
Browse 150+ techniques organized by category
Every time you tag a technique in a session, it's recorded. Open any technique to see a complete timeline — when you used it, from what position, and with what outcome.
Complete training history for every technique
Found a great breakdown on YouTube or Instagram? Link it directly to the technique. Keep all your study material organized alongside your training data so it's there when you need it.
Link instructionals from YouTube, Instagram, and more
Your game is unique. Create your own techniques with a name, category, position, and description — then tag them in sessions just like the built-in library.
Build techniques specific to your game
Go beyond basic stats. Track your net score, analyze position efficiency, spot trends over time, and see the full picture of your training.
See your offensive and defensive stats side by side. Your net score tells you at a glance whether you're winning more exchanges than you're losing — and the detailed breakdown shows exactly where.
Net score and full offensive vs. defensive breakdown
Find out where your game is strongest and where it needs work. Position efficiency shows your success rate from top, bottom, and standing — so you can train smarter, not just harder.
Position efficiency for top, bottom, and standing
Track your mat time and training volume over weeks and months. The trend chart shows how consistent you've been — and makes it easy to spot when you're ramping up or falling off.
Track your mat time and training trends
Everything about your training in one place. Session counts by type, calories burned from Apple Health, supplemental training days, and your most-used techniques — all filterable by time period.
Your complete training dashboard
Train BJJ works with any fitness wearable that writes to Apple Health — WHOOP, Garmin, Polar, Apple Watch, Oura Ring, Fitbit, COROS, Suunto, and more. Heart rate, calories, and duration flow into every session automatically.
Heart rate, calories burned, and workout duration are pulled directly from Apple Health and attached to your training sessions. No manual entry — just train and your wearable handles the rest.
