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 does the alarm clock work, sound or vibration
Answer:	Just a quiet, short sequence of beeps. No vib alarm.
Question:	Is the vivofit 4 that bad? i have a vivofit 3 and its great, but i think i'll skip this version
Answer:	I moved up from a vivofit 2 to the 4. The display is much smaller than I am used to, but it does show more information with the different screens. I was disappointed that you can no longer sync directly with the computer, only with the phone. I do like that it still has the one year battery.
Question:	Does the watch show the date of month
Answer:	Yes.
Question:	What happens when the battery finally dies? Recharge, replace or the device is done? Thx
Answer:	My first one was an earlier model and each battery lasts about 14 months. Take it to a watch shop to ensure the battery is replaced and it is still water resistant. After almost 2-3/4 years the display finally died. I kept wearing it with no display (it still syncs data to the app). Now that it is time for a new battery I am getting the newer model.

User questions & answers

Question:	Can you read text messages on this
Answer:	This product has not been released yet. The scheduled release is mid- October. I have the original and the 2 now, both of them permit text message reads with limited characters. You may not see the entire message. Call FitBit to confirm or send them an email, customer service is awesome.
Question:	should these be turned off when driving in a car? I made a 24 mile trip in my car and it showed i walked 1 mile and burnt 2000 calories and 10 stairs
Answer:	When I cut grass wearing my Fitbit registers at least 30 percent more steps because the handle of the lawn mower vibrates. It's more accurate when I put the watch in my pocket. Doing this when you drive won't solve the problem with climbing stairs but I noticed that my heart rate is higher when I'm driving. The basal metabolic rate calculated from your age, weight, height, and gender make up half of this calculation. Your heart rate and steps taken are used to calculate the other half of this number so putting your Fitbit in your pocket will help to lower your calorie burn.
Question:	Does the Charge 3 have a countdown timer in addition to the Stopwatch feature
Answer:	It has a countdown timer, but you have to select from a scrolling list of times in increments of 15 seconds. It goes up to 60 minutes. So if you want to set a 30 minute timer, you have to scroll through until you can select 30 minutes. I just tried it and to get to 30 minutes, it required 16 swipes.
Question:	Anybody knows if the bands from the fitbit charge 2 can be used on this one
Answer:	I have a 3 and my wife has a 2. She needed a new band and I had an extra band for my 3. I installed my 3 band on her 2 without any issues. Works well.

User questions & answers

Question:	How accurate is the HR tracking for strength training/weight-lifting workouts
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:	Does the screen on the lilac option actually have a purple tint to it
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.
Question:	Is this waterproof? Would it track swimming sessions
Answer:	This does not count steps. it counts movement.
Question:	charger cord included
Answer:	You can use an iPad or similar device, not necessarily iPhone or droid phone. It is just bigger if you have to carry it around while walking or running. For swimming, start the app and leave the phone/ipad in your locker or swim bag. Sync when finished with swim workout. Hope this helps.
