Track your heart rate while doing jiu jitsu, judo, wrestling, MMA, or sambo. Track your effort, take notes, learn what to do in every situation, connect with your training partners, and see how close your next belt or grade really is. GET CREDIT FOR YOUR HARD WORK Tap in and get to rolling. After class, tap out: your workout lands in Apple Fitness and Health with honest calories, shown to you before they're written. You can't wear a watch while grappling, so strap on any Bluetooth heart-rate sensor and every session carries your real measured heart rate, minute by minute, colored by effort from easy to max. Arm a class before you gear up and it records itself from your Lock Screen. YOUR TRAINING, FINALLY COUNTED A trained-day calendar that shows your consistency at a glance. Effort by Session: every class as a bar, colored by how hard your heart worked against your own measured max. Check in at your gym with a single location fix that's matched to the venue and immediately discarded. EVERY SPORT, ONE BODY, ONE RECORD Train more than one art and each gets its own room: your jiu jitsu belt and stripes, your judo grade in your federation's colors, your wrestling seasons, your sambo level, your MMA fight record. Matches and fights count honestly into your competitions and your card. Mat time follows the sport you tapped in for. FOR PARENTS Add your child to your own phone and keep their record where you can see it: every class you tap them in for, the belt they wear, the degrees as the professor awards them, on the real kids belts. Switch between your training and theirs with a tap. No birthdate, no photo leaves your phone, nothing measured: a child's record never touches Apple Health. Photograph the academy's attendance card and the days it marks become classes on the record, read on your phone and never kept. When they have a phone of their own, hand the record over whole. FOR TEENS Your own phone, your own record, on the youth belts. Join your academy as under 18 and they see your name, your belt and the days you trained there, no photo and no heart rate, until the day you say you are 18. A record that began on a parent's phone moves to yours with a code. KNOW HOW CLOSE YOU ACTUALLY ARE Every belt, stripe, and grade you've earned, with the real dates. Randori reads your training and gives you an honest range for what's next: a window, not a date. Your professor decides. EVERYONE YOU TRAIN WITH, IN ONE PLACE Connect with training partners, coaches, and professors by trading profile cards in person. They'll see your sessions, posts, and promotions, so you can cheer and encourage each other. No strangers, no follower counts, no algorithm. A directory of jiu jitsu academies plus judo, wrestling, MMA, and sambo clubs to name your gym. STOP GETTING CAUGHT BY THE SAME THING Write what happened tonight and Randori hands you the answer, on film, from instructors worth learning from. A skill tree for each sport, from the first day to the master tier, with technique names the way they're said in your language. Video plays through YouTube's own player, never copied. The suggestion engine runs entirely on your iPhone; your words never leave the device. YOUR TRAINING STAYS YOURS No account, no ads, no tracking, no streak theater. Your workouts live in Apple Health on your device; your rank, posts, and profile ride your own iCloud, shared user-to-user only with partners you invited. The one server of ours is the academy link, and it holds only what you switched on, for as long as you leave it on. Built for jiu jitsu. Works for judo, wrestling, MMA, and sambo: every grappling art where a wearable doesn't survive the round. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/
