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.

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.
