Built like a tank.

Unlike a tank, it comes in 5 colors.

The LytBand deploys a 100% unibody liquid metal body made in the US and coated with diamond-like carbon finishes. Liquid Metals offers strength beyond grade 5 titanium and with the Diamond like Carbon coating the LytBands gets scratch resistance far beyond sapphire. Dive deep or climb high - the LytBand is engineered to take it.


The band segments are knit from 100% Dyneema — the world's strongest fiber, 15x stronger than steel and it's made in the USA. The connecting sections are elastic, allowing the band to fit various wrist sizes.

When referring to clinical-grade sensors, we mean certified and tested sensors designed for medical devices; this does not classify the LytBand as a “clinical” or “medical” device. Our primary objective is to deploy the best suite of sensors to enhance user awareness of personal wellness and vital body metrics. Sleep apnea is classified as a medical condition. LytBand is not a medical device and is not intended to diagnose or treat sleep apnea.

¹When we refer to “perpetual” or “maintaining perpetuality,” we do not imply that the device can operate indefinitely without any external energy under all circumstances. LytBand generates power from ambient light. If you anticipate wearing the LytBand in environments where exposure to natural light may be less than 30 minutes per day, you may need to manually recharge the LytBand after a week of such low exposure. LytBand allows users to disable perpetuality in the app for advanced professional applications. In such settings, the band will prioritize the user’s settings and will not be able to maintain perpetuality.


Specifications for the LytBand are subject to change. The LytBand may receive feature additions or modifications without prior notice.
