Exercise with a Vibe
The Vivoactive 4s is packed full of fitness-tracking sensors: accelerometer, gyroscope, altimeter, optical heart rate monitor, onboard GPS/Galileo/GLONASS, pulse ox, compass, and a thermometer. Both the heart rate monitor and the GPS have been updated with new sensors, so they should be even more accurate and more efficient than those in previous Garmin wearables. There's also storage space on the Vivoactive 4s for music, and all Vivoactive 4 smartwatches have onboard music storage as a standard feature.
Play More Sports
The Vivoactive 4s, tracks a number of workouts including indoor and outdoor running, walking, and cycling, skiing, yoga, pilates, rowing, elliptical workouts, and more. The strength, cardio, yoga, and pilates workout profiles now support animations, so when you're completing a premade workout downloaded from Garmin Connect, you'll see human animations on the watch screen showing you how to complete each exercise.
Fits You and All You Do
Feel free to take this watch outside in all kinds of weather. Not only is it safe for swimming and showering, its Garmin Chroma Display is easy to read - even in direct sunlight. It also features the Side Swipe interface, which makes for quick scrolling and swift navigation of menus and widgets. Whether you scroll with your thumb or index finger, you can choose how to wear it. Comfortable, convenient and easy to see vivoactive 4s just fits.
Daily Fitness and Stress Tracking
There are a lot of new fitness features on the Vivoactive 4s, but let's start by talking about one that directly affects battery life: optional all-day pulse ox. The pulse ox sensor inside the Vivoactive 4s allows it to measure the level of oxygen in your blood based off of the heart rate and breathing data it collects. Most healthy people will see a pulse ox percentage close to 100 in the Garmin Connect app after the pulse ox sensors gather enough data, but percentages dramatically lower than that could signal health problems. Like most consumer wearables on the market today, the Vivoactive 4s isn't a medical device, but it can capture useful information that users can share with their doctors who can then decide if there's a problem that needs to be addressed.
