A wrist-based Pulse Ox sensor lets you estimate blood oxygen saturation while you're sleeping - or you can spot-check your oxygen levels anytime during the day. The device also monitors heart rate at the wrist and includes helpful tools such as all-day stress tracking, a relaxation breathing timer and VO2 max readings.

To be clear – this unit does not have GPS in it (like the Vivosmart HR+ does), rather, it's the next in succession of mid-range priced activity trackers, meant to compete with the Fitbit Alta HR and Fitbit Charge 2.

A wrist-worn sensor, Garmin Vivosmart 3, can provide accurate and precise records of step counts during overground walking in patients with PD but has noticeably worse estimates of step counts during treadmill walking. Fitbit Charge 2 HR provided poor estimates of step counts during both walking conditions.

While it may not be the most chic tracker out there, the Vivosmart 3 is comfortable enough to wear 24/7. The band breathes easily, so you don't have to worry about it getting grody after a workout. And since it's waterproof up to 5ATM (164 feet), it's also perfectly safe for use in the pool - plus it tracks your swims.

Wristwear. Garmin produces activity trackers and sports watches, aimed at activities such as running, watersports, golf, cycling and swimming with sensors such as heart rate and gps. Some recent models add Bluetooth music playback and pulse-oximetry.

Many of the personal health and activity insights offered by Garmin wearables come directly from or by analyzing heart rate data. This includes features such as all-day stress tracking, Body Battery™ energy monitoring, respiration rate, sleep tracking and even how many calories you burn.

When you receive a phone call on your connected smartphone, the vívoactive® 3 device displays the name or phone number of the caller. NOTE: To talk to the caller, you must use your connected smartphone.

Knows How You Move Move IQ captures different activities, such as walking, running, biking, swimming and using an elliptical, to view on Garmin Connect. No need to switch out your watch or start a new activity, vívofit 3 recognizes when your movement changes so you can go from a walk to a run in no time.

Compared with the readings of an electrocardiogram measurement, the mean percentage error of the devices was remarkably low: less than 1% for Apple and 1.16-1.39% for Garmin. Crucially, this means that both watches could reliably determine what heart rate zone you are working in during exercise.

You can turn on the device and use it with limited functionality, until you complete the setup process on a smartphone or computer. Prior to setup, you can use only the step count, auto goal, and move bar. Your device resets your step count once a day.

If you have previously connected your device to your smartphone or tablet through the Garmin Connect app and the Garmin device is within Bluetooth range of your mobile device, the Find My Device (also known as Find My Watch or Find My Edge) feature may be able to locate it.

For nearly every purpose, people will find an iPhone or Android performs better than a Garmin or other outdoor GPS unit. We believe Gaia GPS is the best app to use your smartphone as an outdoor GPS, but there are dozens of other apps you will likely find preferable to a Garmin, as well.
