SKG Smart Watch, Fitness Tracker with 5ATM Swimming Waterproof, Health Monitor for Heart Rate, Blood Oxygen, Sleep, 1.7'' Touch Screen Bluetooth Smartwatch Fitness Watch for Android-iPhone iOS, V7

This is a great watch, simple, atmospheric, I like it very much. There is a TWO-DIMENSIONAL code on the manual, which can be scanned and downloaded by APP. There are many functions in the APP, including heart rate monitoring, sleep monitoring, blood oxygen monitoring and so on. The smartwatch is waterproof and has good battery life, lasting about a week after a two-hour charge. Monitoring my health all the time, its function is far more than its price, very valuable product.

I wanted an inexpensive waterproof watch that would track my sleeping, oxygen levels, and show when I get texts or phone calls. This watch checks off all of my requirements and the app is pretty user-friendly as well. It does monitor stress level, but that seems like an arbitrary number (it measures it every 10 or so minutes). Overall, I'm happy with this watch, but there are a couple of things I don't like about it. Either it doesn't have the ability or I haven't figured it out yet. I would much rather it automatically read my O2 levels every 10 minutes instead of the stress levels - that information is more helpful for me and I don't believe the stress level reading is accurate. I have to click the side button, scroll to the O2 option and click it every time to read the O2. I also receive a lot of group messages, which I have silenced on my phone, but they still vibrate and go through on my watch (which can drive you crazy if you receive 30 group texts back-to back like I do sometimes). I wish there was a way to silence some messages on the watch, but I don't see that as an option. It does have good options on which app is allowed to notify you, but if you're wanting to receive texts, you're going to get all of them - even the frequent group texts that you've silenced on your phone (I have not tried turning off the notifications on the group texts entirely yet, because I do want them to light up my phone, but if they get too out of hand, I will definitely be trying that). It does have Do Not Disturb time settings, but the watch face still lights up when you move your arm in your sleep, which I would prefer to make it so you had to double tap the screen or use the side button to light it up during that timeframe. Overall, this watch has cool features, like your respiratory quality as you sleep, plans to help develop sleep habits, and weight management.

I was looking for a replacement for my Vivofit4, which died. Didn't want to spend the huge $ that some require, so I found this on Amazon and have been using it for a couple weeks. Still learning how/what to use; but so far - Pluses: 1) Big time numbers - very easy to read. 2) Customizable watch face to show what I want to see at a glance. 3) Great battery life - after a week of wear, it's still 70% charged. I charge it Sunday nights for the week. 4)Activity tracking with 14 activities - I use the Outdoor Walk, Workout and Elliptical. Excellent tracking. 5) Step tracking is right on. 6) Heart rate - watched it through a workout and it appears correct. 7) Veryfit app works well. 8) Documentation is pretty good although I continue to refer to the manual to understand how things work/are working. 8) GPS through the app works well. Minuses: 1) Doesn't seem able to track stress. Could be that my wrist is too hairy. Get the "wear watch tightly" too frequently. Funny though. Seems to do heart rate just fine. 2) Temperature doesn't refresh as frequently as I expected, and can be up to 8 hours late. Does refresh every time I look at the app; but then I'm on my phone anyway, so I may as well look there. 3) Don't seem to have all the functions listed in the manual.Note: I don't use the sleep function. Prefer not to wear it overnight.

I prefer a watch connected to a chest strap and not needing a phone. Unfortunately, those seem to be gone now. The good is that initially I was able to set this up and download the Chinese app and sync the watch to the phone. In using this I noticed first that I cannot isolate the screen to show the heart rate in large font as I did with my polar. Then I noticed that a lot of the time the heart rate did not make sense. I would work out and it would drop. I went back with a chest strap and found that the watch could be 20 beats lower than it should show. tightening up the watch helped some. Not as accurate, but better than nothing. I worked with it that way for about 2 months. Then i found that it would not sync to my phone. I deleted the app and reloaded and tried to reset the watch. My wifi showed both connected but would no longer sync. Then I tried to reset the watch to factory settings to start over. Now it not only will not connect to the app, but it is stuck on a screen showing to download the app. I cannot move forward. It is now totally useless. I wish one of these companies (not Ezon) would come up with an equivalent of the Polar FX7 which was simple, but actually worked.
