Garmin Introduces Vivosmart 4: Slim Activity Tracker With Advanced Sleep Tracking Through Pulse Oxygen Sensor

Garmin has been making serious strides to provide more details on sleep quality and this latest activity tracker includes four sleep stages along with blood oxygen saturation gauging.

    A couple of months ago, Garmin rolled out support for advanced sleep monitoring that includes awake time, light sleep, deep sleep, and REM stage. While my new high end Garmin Fenix 5 Plus supports this functionality, it is great to see Garmin launch the affordable Vivosmart 4 for the masses.

    The only other Garmin device currently with the Pulse Ox sensor to measure blood oxygen saturation is the highest end Fenix 5X Plus. The new Vivosmart 4 has this sensor, but rather than focusing on high altitude training monitoring, the sensor is being used to help Garmin better define sleep quality.

    The Vivosmart 4 is available in multiple colors with metal trim accents in silver, gold, and rose gold. It is safe for the pool and shower with a battery life of up to seven days.

    It has a redesigned Elevate heart-rate sensor, abnormal heart rate alerts, VO2 max support, all-day stress tracking with relax reminders, and more. Basic smartwatch notifications are provided and you can even reply with preset messages if you are connected to an Android phone.

    Dan Bartel, Garmin VP of global consumer sales, stated:

    The Garmin Vivosmart 4 will launch for $129.99. Colors include berry with a gold bezel, powder grey with a rose gold bezel, black with a slate bezel, and azure blue with a silver bezel.

    Garmin Quietly Introduces Automatic Sleep Detection To Existing Activity Trackers

    March 31, 2015Ray MakerBlog

    Over the last few days Garmin has enabled automatic sleep tracking on all of their sleep capable activity tracker devices.  They did so not as part of any firmware update that you have to install, but rather on their backend platform that automatically recognizes when you went to sleep and how many hours of sleep you got.

    For example, last night I used the Garmin Vivoactive with the new functionality.  Normally, I’d have to tap this fancy little button:

    Except last night , I don’t bother to.  Instead, I just fall asleep once I’d declared e-mail bankruptcy for the night.  And according to Garmin, that was about 2:05AM:

    Which, based on my rough recollection of the evening , is pretty much correct. Then, 5 hours and 51 minutes later, at 7:56AM I woke up according to Garmin Connect.  That’s about right, I had whacked the snooze alarm starting about 10 or so minutes earlier, before heading to my laptop to start presenting to people in Asia on a conference call at precisely 8:00AM.

    Now you won’t notice much else different in terms of the graph itself.  It’s still what I’d classify as kinda-not-useful, mostly just looking like waves in the middle of the ocean – and having about as much bearing on my life as waves 2,000 miles off the coast of Nouakchott, Mauritania:


    With that, thanks for reading!


    Commercially Available Wearable Provides Valid Estimate Of Sleep Stages

    Scott Burgett1,Robert Blair1, Darrell Lightfoot2, Catherine Siengsukon3, Adam Reetz1, Suzanne Stevens21Garmin International, 2Neurology, University of Kansas Health Systems, 3University of Kansas Medical Center


    In thelast several years there has been an explosion of smart wearable devices thatare capable of measuring steps, activity, heart rate, and other biometric dataabout the wearer. An estimated 117 million smart wearables will be sold in 2019,with that number rising to 233 million in 2022 .  Actigraphy has been the gold standard for manyyears to estimate sleep stages using wearables. Actigraphy uses accelerometerinformation to estimate wake/sleep periods of the user . Many modernwearables also measure heart rate and heart rate variability by using optical photoplethysmography. PPG uses light emitted into the skin to measure pulse rate by observingsmall changes in the intensity of the reflected light due to capillary blood volumechanges as the pulse pressure wave transits the sensor field of view. The useof actigraphy, heart rate, and heart rate variability together provides theopportunity to estimate more than just wake/sleep, such as light ,deep, and REM stages of sleep.


    The neural network used in thecloud was an adaptation and simplification of the architecture of Zhao .Over 60 features were computed on the device. Seven more features were computedon the cloud over the entire night’s data.

    • Garmin Vivofit 4 First Take: Great Battery Life But No Heart

      The Vivofit 4 is a relatively straightforward activity tracker, although there are plenty of options in the Garmin Connect app. The main draw is its year-long battery life.

      | Topic: Mobility

      The most significant feature of the £69.99 Garmin Vivofit 4 is probably the year-long battery life from its user-replaceable SR43 batteries. This means there’s no need to carry a charge cable. As a regular wearer of activity trackers since they first became available, this has been a very long time coming, and it’s fabulous that it’s finally arrived. How nice it is to go away for a week and not have to pack a proprietary charge cable for my wristband.

      The general build quality is fine, if a bit on the basic side. The one-piece rubbery band is snug enough on the wrist, and my review sample was black with lime-green specks and spots. Plain black and white options are also available, both with a textured finish.

      The 8-colour screen is very small at just 11mm and 88 pixels square. The display is always on, so it’s easy to see the time whenever you want to — provided you can manage with the small screen .

      Upload data from the Vivofit 4 to the Garmin Connect app, where you can view and share a wealth of fitness information.

      Garmin has not given the Vivofit 4 the ability to relay handset notifications. This isn’t a feature I’ve ever used in an activity tracker, so I didn’t miss it here. Frankly, if a text comes in, I’ll pick up the phone rather than look at my watch.

      Is The Garmin Vivosmart 4 A Smartwatch Or A Fitness Tracker

      It’s closer to a fitness tracker but, as we’ll explain below, it’s not the most exercise-focused wearable out there. Instead, think of it more as a health tracker.

      You’ll still be able to receive notifications from your smartwatch, as well as check the weather, control your music, find your phone and reply to texts with preset responses .

      Should You Get An Apple Watch Instead Of A Fitness Tracker

      The Apple Watch has evolved into a one-stop shop, of sorts, for health and activity tracking. But, along with its higher price, the Apple Watch’s battery life gives us pause. The projected 18 hours on the new Apple Watch Series 6 falls far below that of most designated fitness trackers, which often stretch for days . With the Apple Watch, a daily charge is required. The Series 6 unveiled a handful of new health-related features, including a blood-oxygen sensor . An ECG option checks for irregularities in heart rhythm and is FDA-approved. The Health app aggregates all health and fitness data from the watch. You can share workouts with friends and set up competitions. The watch syncs seamlessly to connected fitness equipment like the Peloton Bike+ and the Mirror.

      Apple debuted the Apple Watch Series 6 and the Apple Watch SE in September 2020. We conducted our latest tests on the now-discontinued Series 5 with watchOS 7 , as well as on the still-available Series 3 and discontinued Series 4. If you already have an Apple Watch, it will work well as a fitness tracker. If you want only a fitness tracker, you can get a very good one—the Fitbit Charge 4—for a lot less money than an Apple Watch.

      If you already have an Apple Watch, it will work well as a fitness tracker.

      is straightforward, and its security standards are on a par with Fitbit’s. And Apple is clear about the permissions you grant and the data you share.

      How To Get The Most Accurate Sleep Data With Your Garmin

      We won’t delve into the accuracy debate here, but to ensure you’re getting the most accurate sleep data possible from your Garmin, you need to:

      • Wear your device at least two hours before bedtime and keep it on while you sleep.
      • Make sure your device’s heart rate monitor is on, and the device fits snugly but comfortably.
      • Set your watch as your Preferred Activity Tracker.

      Choosing between Garmin or Fitbit is a big decision for many trying to choose a fitness wearable – and while they may seem similar, in fact there’s huge differences between the two.

      It’s all about the type of data you want – and once you work that out the choice between the two brands becomes much more straight forward.

      For people who live and breathe sports Garmin is a natural choice.

      And while Fitbit has moved way beyond step tracking, it’s still the right choice for those interested in their overall health and wellbeing, with perhaps less interest in hardcore fitness features.

      How Is The Garmin Vivosmart 4 Different From Fitbit

      Garmin VivoFit 4 Activity Tracker 010

      The Garmin Vivosmart 4 and the Fitbit Charge 3 are very similar devices. Both are elite fitness and activity trackers, able to take measurements from the body and provide the user with up to the minute information. The big difference between the two boils down to the ability to track sleep and oxygen levels.

      When Fitbit launched the Charge 3, oxygen tracking technology wasn’t ready. Currently , Fitbit has still not launched a version with oxygen tracking.

      Today, there’s no mention of it on Fitbit’s website, and numerous complaints have come in from consumers who purchased one expecting it to have oxygen saturation tracking.

      It’s not clear from Fitbit’s website if the oxygen sensor will be able to measure oxygen all night long. Sp02 sensors are used for spot checking blood oxygen levels.

      Despite the bad news from Fitbit, the Garmin sleep tracking technology works and is available now!

      Garmin tracks sleep all night long, measures oxygen levels, and tracks movements during sleep. This makes it possible to get a good idea of how good your sleep may be. Overall, the Vivosmart looks like more mature sleep tracking technology and is your watch if you are serious about getting to the bottom of your sleep problems.

      Digging Into Your Data: What Garmin Sleep Reveals

      Each morning you get a full, nightly readout that reveals how much sleep you got in total, along with a breakdown of the time spent in different sleep stages: Deep, Light and REM and also the duration of any periods where you’re awake.

      The sleep stages

      Light Sleep: Eye movements and muscle activity start to slow down as the body prepares for deep sleep.

      Deep Sleep: Restoration mode where eye and muscle movements stop completely, heart rate and breathing slow, and the body goes into recovery, building bone and muscle, and boosting your immune system.

      REM Sleep: The dream stage where the brain is almost as active as when you’re awake. REM sleep is important for forming memories, processing information and resetting.

      In the app, you can add a widget to get your most recent sleep time displayed on your My Day screen. You can get the full sleep breakdown by hitting More and then tapping into your Health Stats. This is also the best place to review your sleep data in the web tools.

      Your data is presented in a timeline that shows you when you fall asleep and when you wake up rather than when you get into and out of bed. If you know there’s an error here, you can manually edit these times in the Garmin Connect app and on the Garmin Connect web tools.

It’s the only fitness band that greets you with a personalized daily goal, tracks your progress and reminds you when it’s time to move.

      Wearables Could Also Be Used In Clinical Trials

      A group of scientists think that wearable technology could be used in the future in clinical trials to help track patient data.

      Smartwatches, fitness trackers, and activity trackers collect a large amount of data each day, and much of it can be useful to scientists testing a new treatment. Wearables could make it less expensive to track the results of a study, and at the same time give scientists a more complete picture of how the treatment works.

      Best Fitness Trackers And Smartwatches For 2018

      Alongside the Fitbit Charge 3, the Vivosmart 4 isn’t short of rivals. In fact, within the Garmin range itself is the Vivosport tracker, costing $169.99, which has more advanced sport tracking than the Vivosmart 4, in a similar form factor.

      Garmin also offers the Vivomove HR, which costs $199.99 but combines classic wristwatch looks, with some of the activity tracking smarts found on the Vivosmart 4.

      Outside the Garmin stable, you’ll find a host of rival smartwatches and activity trackers which, while not offering exactly the same experience as the Vivosmart 4, they do offer some of the same features.

      For example, Samsung recently announced its new Galaxy Watch which, using the Korean company’s new Samsung Health platform, offers sleep and stress tracking. Apple also announced big improvements to its popular Apple Watch models, allowing for yoga workouts and guided breathing exercises.

      We’re also expecting Asus to release its unprecedented, non-invasive blood pressure-monitoring smartwatch, the VivoWatch BP before the end of 2018, after announcing it a few months back.

      What Does The Vivosmart 4 Do How Does It Work

      The Garmin Vivosmart 4 is an advanced activity tracker that includes a Pulse Ox sensor. By measuring blood oxygen and movements during the night, the Vivosmart 4 can give you more insight on how you’re sleeping than any other device available in this price range.

      You may be wondering:

      “How does measuring blood oxygen help improve my sleep?”

      Your body needs oxygen to survive and thrive. When your oxygen levels drop during sleep, it could indicate a host of problems: The Garmin Vivosmart 4 makes it possible to know right away if you might not be getting enough oxygen during sleep.

      It does this by using a Pulse Oximeter.

      How To Track Sleep Using The Garmin Vivosmart

      The Garmin VivoFit 4 Makes Activity Tracking Easy

      You’ll get all of your data on the Garmin Connect App, which is available for both Apple and Android. After you wake up, the app displays the following data about sleep:

      • Stages of Sleep
      • Time Spent in Light, Deep, and REM Sleep
      • Blood Oxygen Levels
      • Movement During the Night

      These readings give you a complete picture of how successful your last night of sleep actually was, right on your phone. You’ll be able to see useful graphs and charts that show you not only what happened, but when. It allows you to see how your sleep has many different facets, and how they’re all connected.

      The Garmin Connect App also keeps track of your fitness and activity data, such as:

      • Steps
      • Fitness Intensity – Literally measuring the amount of time your workout was at its peak!
      • And so much more

      With the Garmin Vivosmart 4, you can literally hack your workout, helping you increase performance and optimize results. The Vivosmart 4 can do so much for your health and your sleep.

      The big question that comes to mind when you look at a fitness and sleep tracker like the Vivosmart 4 boils down to accuracy.

      Just how accurate is Garmin’s sleep tracking? Can it diagnose sleep problems?

      The short answer is that Garmin’s activity tracker is not meant to be a scientific instrument or a substitute for a sleep study. For example, some users have reported the wearable thinks you’re sleeping when you’re watching TV because your hands aren’t moving… But it still has its uses.
