ARC Band
Know your body.
Skip the subscription.
Sleep, recovery, activity and health trends from a lightweight screenless band designed to stay on around the clock. Core app access is included with the device.
Pre-production product. Battery, water resistance and sensor performance remain targets until final validation.
Around the clock
One band. The whole picture.
Recovery
Know when to push.
ARC is designed to combine your personal baseline with signals such as HRV trends, resting heart rate, sleep, recent activity and temperature deviation. Recovery is a wellness estimate, not a medical diagnosis.
Ready for a productive day.
Sleep
Sleep, understood.
See duration, consistency, estimated stages, resting heart rate, HRV, movement and long-term sleep trends in one quiet interface.
Activity
Movement without the noise.
Track steps, active minutes, workouts, heart-rate zones and training frequency without another screen asking for your attention.
Stress
See how your body responds.
ARC is designed to surface daily physiological stress patterns so you can explore relationships between sleep, exercise, travel, late meals and recovery routines without implying a psychological diagnosis.
ARC App
The signal, not the noise.
Today, Trends, Activity, Health and Profile. No ads, no giant social feed and no recurring membership prompt between you and your own data.
