Unlock Your Mind. Unleash Your Potential. Pison helps you reach new heights of human performance and health. The Pison app enables you to improve your whole self. It works in tandem with smartwatches or fitness trackers that are powered by Pison sensors to give you unprecedented insights into your mind, body, fatigue, health, and safety. Note - a Pison-powered wearable and a Pison membership are required. Innovative Sensor Technology Your unique performance and health insights are possible because of Pison’s innovative sensor technology. Unlike other wearables, all Pison-powered wearables include Pison’s novel neural sensor which decodes signals from your mind and nervous system, discreetly collected at the wrist, and gives key insights about your mental state that were never before possible. Some Pison-powered wearables also include other sensors that monitor vital signals such as your heart rate, heart rate variability, breathing frequency, pulse rate, and stress. When this information is blended with the insights from Pison’s neural sensor, you get richer information about your sleep, fatigue, fitness and health. Measure. Understand. Excel. The Pison app enables anyone with a Pison membership, including Pison READY and Pison PERFORM memberships, to monitor three critical cognitive performance metrics: - Readiness - A real-time indication of your ability to mentally perform. It can reveal impairment from fatigue, head injury, diet and disease. - Mental Agility - How quickly you process information, make decisions, and react. In competitive sports or high-stress professional scenarios, Mental Agility is crucial to success. - Focus - A reliable indicator of your ability to maintain attention. This is the gold standard measurement for fatigue testing. If you have a Pison PERFORM membership, you can also monitor additional metrics, including: - Sleep/Fatigue - Sleep time, sleep stages (REM, light, deep, and awake), sleep quality, sleep debt, circadian rhythm - Stress - Emotional reactions - Health - Heart rate, resting heart rate (RHR), heart rate variability (HRV), skin temperature - Fitness - Respiratory rate, calories burned - Safety - Sustained attention (PVT-B) In addition, all Pison memberships allow you to engage with the Pison community through leaderboards and personal groups where you can share and benchmark your performance scores with elite performers, friends, family, and peers. Revolutionary insights drive success Pison helps you measure and track your cognitive performance and physical performance metrics so you can improve your performance. Pison can help you improve cognitive and physical performance: - Optimize training programs. - Adjust diet, sleep schedules or other lifestyle factors. - Understand your circadian rhythm to optimize your preparation schedule. - Detect decreases in performance that may indicate impairment from head injury, fatigue or lifestyle choices, such as drugs or alcohol use. Get focused. Play smarter. Think clearer. Whatever your challenge, wherever your opportunity, Pison delivers unprecedented awareness of your mental and physical state. Realize your full potential—on the field, in the boardroom and beyond.

MirRehab turns limb rehabilitation exercises into an immersive, gamified VR experience — using nothing but your iPhone and a low-cost Cardboard-style headset. Slide your phone into the headset and MirRehab guides you through physical therapy exercises for the elbow, knee, and shoulder. Apple's on-device Vision body-pose engine tracks your joints through the camera in real time — no wearables, no external sensors, and no video ever leaves your phone. HOW IT WORKS • Choose an exercise and target joint on the home dashboard • Mount your iPhone in any Cardboard-style VR headset • Follow the stereoscopic 3D view with a live skeleton overlay and floating HUD • Smart rep counting measures your actual joint angle, so every rep is a real rep • Real-time coaching tells you when to step back, push toward your target angle, or return slowly STAY MOTIVATED • Earn XP and level up with every session • Build day streaks and unlock achievement badges • Complete per-set quests and celebrate with a session summary • Climb the leaderboard and track your progress over time PRIVATE BY DESIGN All motion tracking runs entirely on your device using Apple's Vision framework. Camera frames are processed locally and never uploaded. Your progress syncs securely to your personal account so you can pick up where you left off. WHAT YOU NEED • An iPhone with a rear camera • A Cardboard-style VR headset (low-cost or 3D-printed works great) • A few feet of open space so the camera can see your full body Whether you are recovering from an injury, rebuilding strength after surgery, or keeping up with a home exercise plan, MirRehab makes showing up every day the easy part. MirRehab is a wellness and exercise-guidance tool, not a medical device. It does not diagnose, treat, or cure any condition. Always follow the guidance of your physician or physical therapist.
