Heart Rate, Belt & Calories
Jiu-jitsu is a walk no two people make the same way. Everyone moves at their own pace, on their own road from white belt to black.
The Guard BJJ is a training tracker built around the rituals that actually matter: rolls, drills, stripes, and the long, personal road ahead. Every session logged, every calorie counted, every promotion recorded. Built for the practitioner mindset, not copied from a generic gym app.
LIVE HEART RATE ON THE MAT
Pair a Bluetooth chest strap and see your heart rate in real time. Cardio zones (Z1 through Z5), average and peak BPM. Know how hard your body really works in every round, not whatever your watch guesses afterwards. Syncs with Apple Health.
REAL CALORIES, NOT TREADMILL MATH
Calorie burn tuned to your weight, intensity, and session length. Not a number borrowed from a running app. How much you actually burn in a gi class, a no-gi roll, or an open mat.
YOUR JOURNEY
Stripes, belts, championships, injuries. Your whole jiu-jitsu timeline, from white to black, with the date of every milestone. Date, duration, heart rate, calories, photos, notes: every session in one place, private to you.
SESSION PHOTOS AND NOTES
That session you don't want to forget? Keep it. The post-training shot, the team, the technique of the day, what your partner pulled on you. Every session becomes a memory.
COMMUNITY
Follow your training partners and your gym. See who's been on the mat, react to their sessions. A notifications center keeps the announcements and milestones in one place. You choose what you share.
PROGRESS YOU CAN SEE
Set a monthly target and watch the bar fill round by round; the calendar shows whether you really showed up. A readiness score from your recent intensity, recovery, and consistency tells you when to push and when to rest. Weekly, monthly, and yearly charts: mat hours, calories, average BPM, sessions per week. Spot patterns, catch slumps, train smarter toward the next belt.
WIDGET ON YOUR HOME SCREEN
Your streak and session count right on the home screen, without opening the app. One glance before you head to the gym.
PREMIUM
Go deeper into your own game. See your live heart-rate curve on every round, not just the numbers. Advanced insights reveal where your jiu-jitsu actually lives ("40% of this month was guard passing") and how steady your training rhythm really is. Unlock your full belt journey and unlimited history, then export it all as CSV or PDF. The athlete's edge, season after season.
- Compatible with gi, no-gi, MMA, grappling, judo, and any grappling-based martial art. At the academy, at home, at a seminar, on the road, or on competition day. Built by a jiu-jitsu practitioner, for jiu-jitsu practitioners, from white belt to black.
