So far Not so good

The tracker looks nice and has some really nice functions. I just wish they worked right! It has potential to be so much better. Wore it for the first time last night and the sleep data is WAY off. It says I went to sleep 15 minutes before I even turned off the light and that I didn’t wake up when I really woke up 3 times. And even though I got out of bed at the time it says, I had been awake for awhile. If it is just monitoring the amount of time I am lying down that is useless when it is supposed to be tracking sleep quality. I like the blood pressure function but since the sleep data is so off I wonder how accurate the bp data really is. The sedentary setting appears to be useless also with only a 6 hour window to choose. I can’t even choose a start time in the morning! Let me choose when I want to be reminded to move. I wish that when I pushed the button on the tracker that the screen would stay on longer. It goes off in less than 3 seconds. That is fine if I just lift my hand to check the time but if I push the button to use it I want it to stay on until I am done. I wish there was a way to adjust the time the screen stays on. I found that it doesn’t accurately record my steps when I am mowing the lawn because my arm isn’t moving while pushing the mower. I wish there was a way to fix that. And finally, I wish that the data synced with the health app already on my phone instead of being a standalone app.

Nice But

I recently received my watch. I like the watch, but the app needs some work. While the graphical interface in the app looks good, there are a few glaring flaws. Some of the data sets are in Mandarin. Generally speaking, if you market a product in the US, the data displayed in the companion app needs to be in English. Feed back that is in Mandain, for most people in this market, is no different than gibberish. The sleep data for a day is not cumulative: it records a single event. This is a big flaw- it makes the watch worthless for this function. Many people, more than half, wake up in the middle of the night on a routine basis. The sleep function NEEDS to be cumlative for all sleep periods in a day. This needs to be fixed. Also a big issue: much of the screen text in the app is very tiny, so even with 20/20 vision you need a magnifying glass to read it; the app does not allow you to you zoom-in to see it better. Like the text that is in Mandarin, text that is too small to read is basically useless. I expect many products to have poor instructions for use- this year ne is no different- no worries there- once you poke the buttons enough you’ll get the basic idea of what the main button does...the other two buttons, who knows- they seem to be for looks only. This watch us cloose to being a great product, at this time it is not one mainly because of the app.

Need a lot of work!

The developer needs to work out the bugs in this APP. I wish there was something that worked in its place a “different more accurate app” This thing doesn’t even match what my sleep time it says 8.6 hours on my band but only shows 55 mins on my band. I’ve been told that it only measures certain times but that not true. For instance I went to bed at 10:45pm and woke up at 6:00am it showed the exact time on my band and on this app. This morning it showed I only got 55 mins sleep so it showed something totally different. The first thing I do is sync my band first thing in the morning. But It has nothing to do with time zone, what time you go to bed because it has worked when I went to bed at 6:30 one night I didn’t feel well I slept over 10 hours and it registered the entire time. It has to be something I’m not aware of about how the sleep app works or how to activate it. I was told it can’t be controlled by the band or the app. So I’m going to go through some other apps and do a lot of research today and see if I can find another app that this band will work with. Because it is really screwing up my health log!
