From your wrist to real guidance
No chest straps, no cables, no data-science degree. Here's the simple journey your body's signals take — from the sensor on your wrist to an answer you can use.
Wear the band
Slip Vytal Band on your wrist. Optical and motion sensors quietly read your body while you go about your day and sleep.
It reads your signals
The onboard ESP32 processes heart rate, SpO2, HRV, respiration and movement — filtering out motion noise for cleaner readings.
Your phone syncs it
Readings stream to the companion app over Bluetooth Low Energy, where they become recovery, stress and fatigue you can actually read.
AI turns data into guidance
Ask what your numbers mean. The Vytal backend uses AI to answer in plain language, so you know what to do next — not just what happened.
Engineered to be simple for you
Behind the effortless experience is a carefully built pipeline. Each stage has one job: get you a trustworthy answer, fast and privately.
