Everything Vytal Band reads from your wrist
A complete look at the signals, insights and intelligence packed into one lightweight band. Every capability here is real — grounded in what the device actually measures.
Cardiovascular signals
The core of what your body is doing right now.
Live heart rate
Continuous beat-to-beat heart rate read optically at the wrist — resting, active and overnight.
Blood oxygen (SpO₂)
A pulse-oximetry estimate of how well your blood is carrying oxygen.
HRV — RMSSD
Short-term heart-rate variability, the most responsive read on your recovery and nervous system.
HRV — SDNN
A broader variability trend across your recording window for the bigger picture.
Recovery & load
The insights that tell you how to spend your energy.
Recovery
A daily readiness score built from HRV, resting heart rate and rest — push or recover?
Stress
How much load your body is carrying through the day, so you can respond before you burn out.
Fatigue
An estimate of accumulated tiredness to help you pace training and life.
Respiration rate
Breaths per minute, derived while you rest and sleep.
Trust & reliability
Because a wrong number is worse than no number.
Signal quality
A live confidence score so you always know whether a reading can be trusted.
Motion filtering
The motion sensor separates real physiology from movement artifacts.
Battery level
Always-visible charge so the band never quietly dies on you.
AI health guidance
Ask what your data means and get a clear, plain-language answer.
The hardware behind the signals
Purpose-built sensing, engineered to be reliable and light on your wrist.
Optical HR / SpO2 sensor
A MAX30102-class optical sensor reads heart rate and blood-oxygen at the wrist.
Motion sensor
An MPU6050-class IMU tracks movement and filters motion artifacts out of your readings.
ESP32 core
A low-power ESP32 processes sensor data on the band and streams it over Bluetooth.
Bluetooth Low Energy
The band pairs with your phone over BLE — no wires, no dongles.
Rechargeable Li-Po battery
A rechargeable 3.7V lithium-polymer cell powers the wearable.
