My old watch and it’s accompanying app (of a different brand), seemed to work a lot better than SmartWristband3. The watch is great for what I need and is a heck of a lot cheaper than most watches, but SmartWristband3 is not that great. It does not sync with my watch very well at all! I can have 9000 steps on the watch, but SmartWristband3 may say 8800 and won’t budge no matter how many times I quit it and reopen it. It doesn’t keep the information that the watch has either. When I open SmartWristband3 back up, the heart rate that it synced with will say something completely different, like from the morning. It doesn’t hold onto the new information. Also, my heart rate may reach 134 beats, which is cardio level, but it will say I have only reached 8% fat burning and show no cardio. It’s really frustrating. It’s like SmartWristband3 has a bunch of bugs that needs to be fixed!!!
