01 · The form
Nothing to look at. Everything to learn.
A matte pill module on a soft woven strap. No screen, no buzzing feed, no reason to take it off at night. ARC is built to disappear on your wrist so the data can keep coming.
- Screenless by design
- Woven strap with slide buckle
- Replaceable straps
02 · The sensor
Close to the skin, all day and all night.
The underside carries optical and motion sensing plus skin temperature, reading quietly in the background. Over the first weeks ARC learns your baseline, then shows what changes.
- Multi-wavelength optical sensing
- Accelerometer and gyroscope
- Skin temperature trends
03 · The price
$0/month.
Many wellness trackers keep your scores behind a paid membership. ARC does not. Order the band for $99 and the core ARC App comes with it: sleep, recovery, activity and trends, with no required subscription.
