Kin | Performance Intelligence vs RYZN

Kin is a performance intelligence system built to understand what actually drives your performance. Originally developed with elite athletes, Kin combines daily reflection with physiological data to reveal the patterns behind your best and worst days. So you can stop guessing and start making better decisions. How it works 1. Daily performance check-in Log how you felt, performed, and recovered in under a minute. 2. Connect your data Sync sleep, recovery, and training from your wearables. 3. Reveal your patterns Kin analyzes the relationship between how you feel and how you perform. What makes Kin different Most apps track metrics. Kin connects: • How you feel • What you do • How you perform Then turns it into clear, actionable insight. What you get • Personal performance insights based on your real data • Pattern recognition across recovery, stress, training, and habits • Daily guidance tailored to your current state • A system that gets smarter over time Built from elite performance Kin started with professional athletes. The goal was simple: Understand what actually leads to consistent high performance. That same system is now available to you. For two use cases • When performance feels inconsistent and you don’t know why • When you want to reliably replicate your best days This is not another tracking app. This is the system that helps you understand yourself.

RYZN is the fitness tracker built for lifters who actually lift, and eat with intention. Snap a meal photo and watch RYZN identify it in two seconds. Mark a set from your Apple Watch without breaking stride. See your live heart rate on every working set. This is what training apps should have always felt like. Apple Watch, your wrist, your coach Start a workout, mark sets done or to-failure, see live BPM, and watch your rest timer tick down, all from your wrist. A 6-hour heart rate sparkline on the watch face tells you exactly how your body's been responding all day. No double-logging. No second login. 239 exercises, every one demonstrated Barbell, dumbbell, machine, cable, kettlebell, bodyweight and bands. Open any exercise and a short looping clip shows you exactly how it's done, with the working muscle highlighted in your accent color. Seen enough? It folds away the moment you log your first set. Want the full breakdown? Tap the clip. Track everything that matters Log sets, reps, and weight for every exercise. RYZN auto-cascades your last performance so you're not punching in the same numbers every session. Add drop sets with a tap: drop the weight, keep going. Time-based moves like planks and L-sits get a built-in countdown timer. Swap exercises mid-workout without losing your place. Add bodyweight warmups before your working sets, and log cardio with live heart rate and calorie tracking. Don't know the machine? Point your camera at it Walk up to any machine, point your camera, and RYZN names the exercise and loads it into your workout. No more guessing what that contraption in the corner is called. Tap a tag, start the set RYZN Tags are stickers that go on gym equipment. Tap one with your phone and the exercise opens, ready to log. They work for people who don't have RYZN too: tapping a tag opens that exercise, or the full list of movements for that machine, right in the browser. Fuel like a pro, not a calorie counter Take a photo of your meal and RYZN recognizes the food, estimates macros, and logs it. Diet Coke in two seconds. Chipotle bowl in three. Voice-log a snack between sets. Built specifically for people who care about protein, calories, and recovery, not people obsessing over a 50-cal margin on a salad. See your muscles work A dynamic muscle map shows exactly what you're hitting, color-coded by volume so you can spot imbalances at a glance. No more "did I already train shoulders this week?" Drop the muscle map widget on your home screen to see your week's volume and workout count without opening the app. Train with your team Coaches can build programs, assign macros, and see their roster's real logged data. Athletes get a leaderboard, shared goals, and a feed built from actual workouts. Sleep and recovery RYZN reads your sleep alongside your training and heart rate, so rest days are a decision, not a guess. Finish strong Every completed workout ends with a summary card you can share: exercises completed, total volume, muscles trained. Show your work or keep it to yourself. Your data, your account Workouts, meals, and profile data sync to a private RYZN account so you can switch phones, pair an Apple Watch, or train across multiple devices. Delete everything from Settings any time. We never sell or share your data, period. Designed for the dark RYZN is built in dark mode because nobody wants a flashlight in their face between sets. Students: verified university students get RYZN at a permanently reduced price. Verify your school email on the subscribe screen.
