Garmin Vivosmart 4 with pulse ox, Body Battery energy

Garmin Vivosmart 4 released

Garmin has launched the Vivosmart 4, and based on its features, the wearable is meant to be a direct competitor to Fitbit’s Charge 3. The Vivosmart 4 comes with a blood oxygen monitor called “pulse ox,” and a new feature Garmin calls Body Battery energy which tells you the optimum time to workout.

I reviewed the Vivosmart 3 (which can be found here) and this model is even slimmer than that with its monochrome touchscreen. The Vivosmart 4 comes in 4 colours,

Black with Midnight, Gray with Rose Gold, Berry with Light Gold and Azure Blue with Silver with them all at the same price point of $129.99. The new wearable from Garmin features a silicone band with an aluminium case

Vivosmart 4 Body Battery energy monitor

Body Battery energy monitor that estimates your body’s energy reserves, letting you know the optimal time for activity and rest. Using a combination of data gathered from stress, heart-rate variability, sleep and activity, a higher Body Battery indicates the time is optimal to be active whereas a lower number suggests rest is in order,” Garmin says. “Body Battery assists users in making sense of patterns, demonstrating how behaviours and activities of the past few days influence how one feels at a given moment.”Vivosmart 4 colour

Vivosmart 4 Pulse OX

Pulse OX was first released with the Fenix 5x Plus Series to monitor blood oxygen saturation levels at higher altitudes, but Garmin has decided to monitor your blood oxygen saturation levels at night to help you better understand your sleep quality.

Just over a month ago Garmin introduced advanced sleep monitor estimates light, deep and REM stages of sleep, along with movement throughout the night which you can view in Garmin Connect, so its going to be really interesting to see how the PulseOX sensor helps with this type of analysis.

Vivosmart 4 is pool and shower proof and can last for up to seven days between charges, but being honest it will be around 5 days with a fair bit of use.

Garmin’s redesigned Elevate heart-rate sensor, new abnormal heart-rate alerts, which was also first introduced on the Fenix 5 Plus Series along with O2 max, stress tracking and activities for walks, runs, strength training, pool swims, yoga and more, but it introduces a new wrist-based pulse ox sensor.

Android users can even reply to texts with preset messages. All of these features really add to the appeal of the fitness tracker.Vivosmart 4 released
