User questions & answers

Question:	Will my charge 3 bands fit the charge 4? Would i need to purchase new bands, again
Answer:	Charge 3 bands are interchangeable with Charge 4 bands. They're the same exact size.
Question:	Will this watch offer heart rate variability tracking or collect data that can be extracted by an app for hrv tracking
Answer:	yes
Question:	Will a regular charge 4 band fit on the charge 4 special edition? Looks like it has special connections
Answer:	From the best I can tell from all the internet research I've done the only difference in the 2 fitbit is the band or strap material. Otherwise they are exactly the same. They give you a fancy band and charge you more. Otherwise the fitbit 4 is identical the the fitbit 4 special edition.
Question:	Does GPS require paying a monthly fee to anyone or is it free
Answer:	Until Fitbit allows GPS phone tethering on the Charge 4 - you are better off with a Charge 3 (or Charge 2). Otherwise you're looking at 1-2 hours battery life while exercising with GPS, missed stats, and constantly recharging this thing (more often than an apple watch). Fitbit could fix this tomorrow by allowing tethering, but they do not, and are censoring the issue on their forums. Don't downgrade!

User questions & answers

Question:	How accurate is the HR tracking for strength training/weight-lifting workouts
Answer:	It’s pretty accurate. I was using this while hooked up to a halter monitor. It was very close.
Question:	Does the screen on the lilac option actually have a purple tint to it
Answer:	I put it next to paper, white sheets and and a white napkin and covered the bands. The images do have a purple tint. It appears that the whole “watch face” is a purple tinted continuous surface. So yes, your eyes see real lilac. There are grey tones and thus some grey dots where the image needs depth or delineation. So, the majority is light lavender and the remainder is grey. It’s pretty darn cool and pretty, too. You will like it. ( my sis has a black band and I also compared face-to-face with hers). Enjoy!
Question:	Is this waterproof? Would it track swimming sessions
Answer:	Yes its waterproof up to 50 meters. Yes it will track swimming sessions. I believe it will track swim duration and distance/laps. The Inspire doesn’t allow you to set the pool length like the more expensive models do though. The HR feature is disabled while swimming. It will automatically recognize swimming (the default is 15 minutes but you can change it to recognize it after 10 minutes of swimming) or you can manually start a swim session through the tracker itself which is what I do with most of my exercises.
Question:	charger cord included
Answer:	The charging cord is included, but it may not have the original fitbit charging cord. It is supposed to come with a charging cord that has a button toward the base so that you can restart it if needed, like if the display goes away. The cord that I received through Amazon does not have this button, so restarting it is a bit trickier.

User questions & answers

Question:	Can it continuously display heart rate without having to switch screens or waking it up
Answer:	Mine won't. I have to tap it to wake it up then scroll to get to the heart rate screen each time. However, I'm still learning about all of the things it will do.
Question:	There is no band size indicated on the page. Where do you find which size it is
Answer:	They are all s/m except the black has two options, one s/m and one L.
Question:	Does this track stairs
Answer:	It is suppose to track flights of stairs. Had a replacement because the first one did not. The new one was only slightly better. Counted 3 out of 6 flights of stairs. Was almost better at counting descending flights.
Question:	Has anyone compared the spo2 oximeter readings with another oximeter to see if they are accurate? My readings seem to be off
Answer:	I’ve compared it with a pulse oximeter on the same hand. Took a reading following instructions (stay still, arm raised at heart level). If worn the traditional way, the spo2 reading is off by 3% (a 98% on pulse ox will read 95% on the Garmin) consistently for me. If worn the way they recommend (further above the arm) for a sp02 reading, it is accurate and matches an oximeter.

Product features

Pulse Ox at Your Wrist

The Pulse Ox sensor on vívosmart 4 estimates your body’s blood oxygen saturation level. Your Pulse Ox measurements are dependent upon a number of factors, including your overall health and fitness. Checking your Pulse Ox 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 performance. To give you an idea of how you’re sleeping, vívosmart 4 tracks your light, deep and REM stages of sleep, along with movement throughout the night. For added insight, turn on the Pulse Ox 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 Garmin Connect Mobile app.

Optimize Your Body’s Energy

Body Battery energy monitoring on vívosmart 4 uses a combination of stress, heart rate variability (HRV), sleep and activity data to gauge your body’s energy reserves at any moment, so you can plan your day to optimize 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 and rest a bit before tackling a workout. Body Battery can also help you make sense of patterns throughout your weeks, so you can understand how the past few days have influenced how you’re feeling today.

All-day Stress Tracking

You most likely experience stress at some point in your day, but how much? Your vívosmart 4 lets you know when you are having a calm, balanced or stressful day and everything in between. Tracking your HRV (the time interval between each heartbeat), vívosmart 4 calculates and displays your stress level. There’s also an optional 'Relax Reminder' feature that you can turn on in the Garmin Connect app. If your stress level gets elevated during your day, it will provide a vibration alert on your wrist and display a message (“Take a moment to breathe?”) to let you know it’s time to relax. 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

Using the Elevate heart rate data collected from your wrist, vívosmart 4 can — with a VO2 max estimate — give you an idea of your current fitness level. In general, as your aerobic fitness increases, your VO2 max does the same. 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. For added insight, vívosmart 4 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.

Stay Connected

With a vívosmart 4 tracker on your wrist, you don’t have to choose between staying connected and staying more active. Check the weather, control your music, receive smart notifications, find your phone, even reply with preset text responses (Android only), and access social media notifications on your tracker’s display — all while keeping your smartphone stowed away.

Keep Track of Your Active Life

Your vívosmart 4 greets you each day with a personalized step goal. Then it tracks and displays your progress. In addition to steps, its activity tracking capabilities include floors climbed, calories burned, intensity minutes and more. You’ll also see a move bar and get vibration alerts to remind you when it’s time to get up and move.

Track Your Workouts

You can use the preloaded activity timers to keep track of your exercise times and more. When using the strength training activity, it estimates your exercises, reps and sets along with your work and rest times so you can leave the notebook at home. And if you forget to start a timer, the Move IQ feature on vívosmart 4 will automatically detect exercises such as walking, swimming, cycling and elliptical training — and it even starts timing select activities. When finished, your activities are pushed to Garmin Connect, our online community, where you can review, edit and share the activities with your connections and friends.

Notes:



1. Four built-in watch faces. You can replace two of the built-in watch faces from a selection of 40+ online watch faces in the Zepp App.



2. Test conditions: the device is fully charged, the automatic heart rate measurement feature is enabled for 10 minutes, the Activate on Raise feature is enabled, and other settings are kept in default states. Each day involves the following operations: 50 notifications are received and displayed, 200 screen activations on raise are conducted, outdoor running every other day for 30 minutes and SpO2 measurement twice per day. During actual use, battery life is related to various factors such as settings, operations, and operating conditions, and therefore may differ from laboratory data.



3. Based on the ISO 22810:2010 standard, the watch delivers a water resistance level of up to 50 meters and has passed the test conducted by the BUREAU VERITAS CONSUMER PRODUCTS SERVICES. The report number is XRX-ESH-P20062078.



4. This product is not a medical device. All the measurement data and results are provided for reference only and cannot be used to perform professional diagnosis or monitoring of any medical conditions.

6. This product is not a medical device. All the measurement data and results are provided for reference only and cannot be used to perform professional diagnosis or monitoring of any medical conditions.

7. The Personal Activity Intelligence is a personal physiological activity indicator. Based on heart rate data, daily activity intensity, and multidimensional dynamic comprehensive evaluation of personal physiological data, it's converted into an intuitive PAI value using an algorithm to help you understand your physical condition without relying on single data. According to the HUNT Fitness Study research results, keeping your PAI value above 100 reduces the risk of death by cardiovascular disease and increases life expectancy.

User questions & answers

Question:	can you connect a 4iiii flight trainer
Answer:	I heard a rumor that there's a guy whose only job is to make sure the factory workers don't stow away in the boxes shipped out of the country. So, going off of rumors I just made up, I can guarantee you won't find any stowaway factory workers in the box and I can confirm, one wasn't present in mine.
Question:	Does the M2 accept all standard smart trainer ? Only wahoo is listed
Answer:	I have tried with the best spec HDMI and it only displayed at 60hz. For 144hz, I believe you beed display port. Maybe there was something wrong with the HDMI cables I tried. I tried multiple ones that claimed to support the latest standard.
Question:	Does the polar wathces connect its with vdot 02?app for trainers
Answer:	Regrettably, we do not have a list of recommended power cable extensions that can be used with the AC/DC adapter for the LG 38” UltraGear™ 21:9 Curved WQHD+ Nano IPS 1ms 144Hz HDR 400 Sphere Lighting 2.0 3-Side Virtually Borderless, Model # 38GL950G-B.

Polar Vantage M2

Polar Vantage M2 (weighs only 45 g) is packed full of features like accurate wrist-based heart monitoring, running program, ready-made daily workouts, inbuilt GPS, recovery tracking & smart fueling assistant.

Polar Vantage M2 is designed for that athlete attitude. If you love to keep finding new ways to stay fit and stay motivated, it’s your all-in-one companion on your way towards new PR’s.

WHY HEART RATE TRAINING IS THE SMART WAY TO WORK OUT?

Real-time heart rate data during your workouts means instant insight into how your body is responding. You’ll be training smarter, which is always better than simply training harder.

In a nutshell, smart training that leads to results is based on three variables:

Frequency: How many times you exercise during a period of time, for example per week.

Duration: How long you exercise at a time, usually counted in minutes.

Intensity: This one is a bit more complicated – and that’s where your heart rate comes in.

Your heart rate is one of the best indicators of how hard your body is working during training. Instead of trying to ‘guesstimate’ the intensity of your workout, your best bet is to rely on your heart rate which is a trackable number, just like frequency and duration.

Performance isn’t just about training smarter – recovery plays a huge part as well. Our Nightly Recharge recovery measurement automatically tracks your sleep and recovery, so you’ll know when you’re ready to push your limits.

Running Program

A running coach on your watch - with Polar Running Program, training for a running event is easier than ever. All you need to do is choose your distance and set your date, and Polar Flow creates you a personal and adaptive training plan that is based on your individual metrics. Your plan adapts along the way based on your progress.

Training Load Pro

Training Load Pro helps you see how your training sessions strain the different parts of your body. It also gives you a visualization of how much you’ve been training lately, so you’ll know whether you’re on the right track.

Nightly Recharge sleep tracking

Nightly Recharge is an overnight recovery measurement that shows you how well you have recovered from the demands of your day. It helps you make optimal choices in your everyday life to maintain overall wellbeing and reach your training goals.

All you need to do is wear your Polar Vantage M2 during the night – the measurement is completely automatic.

Every day, the screen turns on to display 50 messages, and the user raises the wrist 200 times to check the time. The user exercises 90 minutes every week. The heavy usage refers to the following condition: Worn for consecutive 24-hour periods, heart-rate monitoring (data recorded every 1 minute) and sleep monitoring are turned on, sleep breathing quality and all-day stress monitoring are enabled, and SpO2 is measured twice a day.

Note: For people with dark skin, the battery life will be further reduced with heavy usage.
