User questions & answers

Question:	Will my charge 3 bands fit the charge 4? Would i need to purchase new bands, again
Answer:	The watch has a Exercise section that has running, weight lifting Biking, treadmill, Elliptical. workout. You can tap on the one you want without having the phone with you. I don't even own a phone. I use a table but I just did a walk outside and it detected my 10,000+ steps and recorded the miles. It may be more accurate with the phone. I used windows Tablet and/or Windows10 with GPS and they both sync with when I got back and it said the same amount of steps as on my watch. I think it is pretty close anyway. You can see everything on the watch. That is why I like it a lot. I didn't think I would be able to see anything except heart rate and steps.
Question:	Will this watch offer heart rate variability tracking or collect data that can be extracted by an app for hrv tracking
Answer:	There is a music control option (either swipe down from the top of the main screen, or use the top right button on the edge of the watch casing). I have not used it yet. You get notifications such as texts & calendar alert and phone calls by a buzz on the watch. Texts are displayed as soon as I get them on my phone. Simple swipe from the bottom of the screen up lets you review them. You can then simply swipe right to dismiss them or scroll down through all of them to a "clear all" option.
Question:	Will a regular charge 4 band fit on the charge 4 special edition? Looks like it has special connections
Answer:	"My Blaze is 2 DAYS AT THE MOST" This is my 4th Fitbit watch over the past 4 years and this Blaze is the worst ever on the battery life. Because of this, this will be my last Fitbit. I will be checking out the Apple Watch when this one drops dead from exhaustion. I am 73 and this Fitbit can't keep up with a grumpy-ole-man! I have found that everyday when I shower, I put the Blaze in the charger and that seems to keep the thing from dropping dead on me when least expected!
Question:	Does GPS require paying a monthly fee to anyone or is it free
Answer:	I have a 38mm apple watch and the blaze. The screen of the apple watch is the same size as the blaze if you turned the apple watch display sideways. The case of the blaze (it fits into the band) is a bigger overall footprint than the Apple Watch. That said, the Blaze is much more flush with your arm and doesn't stick out and feel bulky like the Apple Watch. Bigger footprint, but lighter and less noticeable when wearing if that helps.

User questions & answers

Question:	Does it come with the normal apple guaranty or is it better to buy it in an apple store
Answer:	Same as Apple Store. And you have 60 days to add AppleCare+ which I highly recommend. I added it online after receiving my watch and making sure all was ok.
Question:	Does this apple watch come with adapter? It says so, but I cannot find it in the box
Answer:	Ours just arrived Nov 2019, and it has an adapter. Contact the seller. The watch looks and feels of great Apple quality. I won’t know until the holiday if it’s working because it is a gift. It has on band that is adjustable, not two and someone else stated below. No box, but in a good bubble wrap envelope sleeve. Fingers crossed that he loves it. If not, it can be returned up to 90 days!? From what I understand.
Question:	What is the difference between the watches that have only gps and the ones with gps+cellular
Answer:	The ones with cellular allow you to use your watch without your phone or wifi. If you get the gps+cellular, you do not need to have the watch activated with cellular service. If you don't have the gps+cellular watch activated with cellular service, it works just like a gps only watch. Also, the gps only watch is 8gb vs 16gb for the gps+cellular.
Question:	What is the difference of the 38mm and the 42mm
Answer:	the 38mm is 4mm smaller than a 42mm and most of the people who can afford these (RPR) would buy the larger one unless you have tiny wrist.

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.

Black+ blue (free band) Blue+ black (free band) Red+ black (free band) Green+ black (free band) Purple + black (free band) I hope this can help you fix your issue. We don't have separate replacement band to sell on amazon. (The stock of replacement band is limited.）
