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:	Can you wear this one swimming
Answer:	Hello dear customer Thank you for your interest in our smartwatch. You can't wear it while swimming, because there is a risk of water seepage in the water for a long time. It can't be worn when taking a bath. The water vapor in the air has a small radius and easily penetrates into the gap of the case. When the temperature drops, it will condense into water droplets, which will easily cause an internal short circuit. But you can wear it when you wash your hands, wash your face, and rain.
