Cortisol, Electrolytes, Blood Glucose & Lactic Acid Trends
Electrochemical Sensing
Deploying our groundbreaking nano-lattice structure, the LytBand is the world’s first wearable device to deliver the ability to sense cortisol levels, electrolytes such as sodium and potassium levels, and lactic acid buildup in a sleek, seamless band that you never* have to take off.
The electrochemical sensor works along with our spectrometer and PPG to get highly precise blood glucose^ trends

Powered by Light, 512Gb storage, transfer rate of up to 3.8Gb/s.
Perpetual
Powered by custom-built thin film solar cells, the LytBand is developed on a completely new wearable platform that’s light years ahead of the status quo.
512GB of high-speed storage, wired Thunderbolt data transfer + BLE 6.2. Ultra-high-density lithium ceramic battery. Onboard true convolutional neural network AI compute.

100Hz HR, HRV, perspiration, VO2 max, EMG, motion, altitude, depth, fall detection & optional DR-GPS.
Activity and Navigation
LytBand is the world’s fastest activity tracker. Log everything from steps taken, calories burned, HR, HRV, motion vectors, perspiration, EMG at up to 100Hz (full raw data) on lightning-fast 512GB onboard storage, 5000x larger and 80x faster than any wearable.
World’s most accurate high-precision DR-GNSS with UWB, hardware compass, altitude and depth (up to 100m dive rated), 9 DOF AI activity classifier.

Sleep Score, Sleep Apnea^ SpO2, Sleep HR, HRV, Body Temp, Motion. Ambient Temp, Light & Noise.
Sleep Tracking
LytBand is the most accurate non-medical sleep tracker sensing HR, HRV, SpO2 (Sleep Apnea^), body temperature, perspiration levels, respiration rate, and motion, all at 10Hz while you’re asleep. Proven across multiple sleep score benchmarks comparing Apple iWatch Ultra 3, Whoop Strap, and Oura Ring. LytBand delivers up to 50% higher accuracy.
The LytBand is also the only wearable that factors in room & body temp., humidity, air quality, and ambient light as factors affecting your sleep. Sometimes it's not just you!

Body Composition & ECG AFib Detection
Electrical Sensing
Deep dive into how your body is evolving by the pound. Get relative body fat, muscle mass, bone mass, fluids, and visceral fat.
The electrodes are shared with onboard single-lead ECG for AFib detection.

Privacy – ARM TrustZone-certified, onboard end-to-end encryption
Privacy
Thanks to the latest ARM TrustZone-certified architecture, LytBand has hardware-level data encryption. LytBand is also the first wearable to deploy our patent-pending “Device as Cloud” tech that keeps all your data on the band and only beams required data to the app while you’re using the device.

UV Index, Air Quality, eCO2, Humidity, Altitude, Depth
Ambient Intelligence
LytBand is the world's first wearable to offer a suite of sensors to understand your environment like never before. The band can sense Air Quality Index, PM1, PM2.5, PM10 particles, eCO2, VOCs, VSCs, humidity, ambient temperature, pressure, depth (up to 100m), and altitude. Environmental sensors are normally tuned to read once every second.

100% Flagship Clinical-Grade Sensors. 100Hz raw data rate.
Flagship sensors
All vital signs, motion and ambience sensors along with light sources and receivers on LytBand are absolute flagships from Bosch (Germany), Texas Instruments (USA), AMS Osram (Austria), and Analog Devices (USA). All electrodes for ECG (for AFib detection), EMG, EDA/GSR, BioZ (for body composition) are 24K hard gold-plated for extremely high precision and longevity.
All sensors on the LytBand are capable to log data at up to 100 times per second. That enables an array of capabilities like catching precise HR peaks when you're revving at 180BPM (3+ beats per second), enabling extremely accurate fall detection, catching racquet shorts with precise impact vectors times down to the microsecond.

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.

^LytBand is not a medical device and is not intended to diagnose or treat any medical condition. All features are designed solely for wellness purposes. 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. The sensors measuring respiration rate and blood oxygen levels during sleep are designed exclusively for insight and awareness. If you suspect you have symptoms of sleep apnea, consult your primary care physician, a sleep specialist, or another qualified medical professional for diagnosis and treatment. This statement does not constitute medical advice.
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.
