Sleep tracking doesn’t work

The sleep tracker is not working. I am completely happy with all the other functions, which work great. But my bedtime, because of my wife’s health problems, is around 2am. My wake up time varies but it is usually around 9am. I have had the watch for three nights. All three nights I went to bed around 2am, except for last night I went to bed at 3:20am. All three nights the tracker showed the exact time that I woke up, got up. However the first night it showed me going to sleep at 11:45 and the next two nights it showed me as going to sleep at 8:45pm. How can it get the wake up time spot on, but show me going to sleep over 7 hours before my actual bedtime and during one of my three days most active times? The other functions work great and the sleep function is nice to have but not needed, the other functions are and they work great. They are the reason I bought the watch and I am completely happy with them. It is a three because of the sleep tracker, it is a solid five otherwise.

Day band and kore trak

This app is a pretty good app and so far I’m loving this kore trak. It’s almost like a Fitbit but kinda more advanced. It’s advanced because you can see your messages but sadly you can’t text on it. It also vibrates when someone texts you so it comes in handy for when my mom needs help with groceries or sends me my chore list so I can look at my chores when I need to. This app tells you how much percent your kore trak is at and you can also change the settings on the kore trak. I would also not recommend using the alarm to wake up unless you are a light sleeper, this is because when the alarm goes off it only vibrates and I’m a deep sleeper. The alarm can be used for day time purposes like if your baking cookies and need to set an alarm you can use your kore trak alarm. I literally just got my kore trak last night and so far I love it, I got it as a Christmas present from my landlord but I got it earlier. If you want something different from a fitbit and be able to set a stopwatch or anything else like that and be able to see your messages I would highly recommend it. I love this brand and it works great. And also it completely syncs up with your phone depending on the distance. People just don’t think it does cuz they don’t completely read the instructions prob.

I was excited to receive this watch. I had ordered it with the purple band, but it came in black. That was the first disappointment. I set the watch up and wore it on my left wrist as it prescribed. I also wore my Fossil hybrid smart watch on my right wrist. Just to see how accurately they corresponded. They were vastly different in details. I’m not in the greatest health so I felt I needed the BPM and BP parts of the watch. I want to get my money back for my watch, and my husband was terribly disappointed also, so wants his money back also. But, since we already had thrown out the packaging they came in, we won’t be able to be refunded. That isn’t fair, and since we are both disabled and retired, it was hard to cough up that much money for wishful thinking watches. And the fact that they don’t actually tell you it only comes in black band, it’s misleading. And the customer service is terrible. I called several times to be told that I could not order the different color bands on the phone. That I would have to use the link I was sent. I am not interested in a pink or white band. When I tried to order another band through an ad on AOL, when I chose purple, it kept going to orange. Sorry. Y’all are a scam company. I’ll probably just throw these pieces of junk in the garbage.
