Technical Information

Stylish design

This slim tracker, available in multiple colours, complements your style with its stylish wristband and bright, easy-to-read display. The display is only on when you need it. And when it's on, it auto-adjusts to ambient light levels, so it's visible even in bright sunlight. Whether you're going to the office, the gym, the pool or anywhere in between, VIVOSMART4 is the perfect fit for your lifestyle.

Pulse oximeter at your wrist

The pulse oximeter on VIVOSMART4 estimates your body’s blood oxygen saturation level. Your pulse oximeter measurements are dependent upon a number of factors,including your overall health and fitness. Checking your pulse oximeter can help gauge how your body is absorbing oxygen. Turn on the feature to gauge your SpO2 overnight, or use it to take a spot measurement anytime to learn more about your body..

Advanced sleep monitoring

Sleep is important to your overall health, well-being and physical fitness. To give you an idea of how you’re sleeping, VIVOSMART4 tracks your light, deep and REM stages of sleep, along with movement throughout the night. For added insight, turn on the pulse oximeter feature to view your blood oxygen levels during your sleep. When you wake up, you can easily review and compare your sleep stats in the app

Analyse your body's energy

The Body Battery feature uses a combination of stress, heart rate variability, sleep quality and physical activity data to gauge your body's energy reserves at any moment in your day,so you can plan your day to optimise times for activity and rest. A higher number indicates you're ready to be active, while a lower number suggests you might need to relax

Stress tracking

You most likely experience stress at some point in your day, but how much. Your VIVOSMART4 lets you know when you are having a calm, balanced or stressful day. Tracking your heart rate variability, VIVOSMART4 calculates and displays your stress level. Use the relaxation breathing timer, which walks you through the fourfold breathing technique, proven to calm your mind and body.

Daily fitness and wellness monitoring (1/2)

Using the Elevate™ heart rate data collected from your wrist, VIVOSMART4 can — with a VO2 max estimate — give you an idea of your current fitness level. Based on your VO2 max, vívosmart 4 is also able to estimate your fitness age — a stat that you may be able to decrease over time with hard work and exercise.

Daily fitness and wellness monitoring (2/2)

For added insight, it will notify you if your heart rate unexpectedly rises above a threshold you’ve set. If you're inactive for more than 10 minutes and your heart rate stays above your set threshold, you’ll get an alert.
