ZeFit

I keep on receiving "Invalid message received from server" when I try to log in with my Samsung S7 Edge phone so I use my PC but it won't record my sleep data. So either way it's not working properly. And I had bought this product for the sleep data feature. So it's useless now. What's weird is that I was able to log in to my phone once.

I used 3 smart phones all cant detect the GD watch!! I used 2 computers and same thing it cant detect it!! I even sent an email for assistance and Im still left hanging, junk!!

I can't log in, error is: invalid message from the server, why? I rated 1 but i want to rate 0

I'm surprised that both software and hardware work really bad. I am not able to sync using either my PC or my mobile phone. Memory is full so probably I won't be able to refresh it and track my activity again

Zero star. I've been communicating with their support for over a month. They still cannot resolve the sync problems.

Battery dies in about 10 mins dont waste your money

Doesn't work, never sync using with 3 different device's

Doesn't work for Android devices. Only for iOS. Please make an update..

Error, not pairing.... Deleting.

Updated it and still doesn't pair so my view is thus far it's been crap

I always give apps a fair go, the design of the ZeFit watch is nice, I like it. But the Android App is rubbish! On the product packaging it clearly states that you can do everything through the app, which is why I bought it. The ZeFit doesn't sync with the app, it Just says a new version of the software is now available please download it for the PC. Well I don't have a PC, so a lie. I contacted support and they say all they say is yes use a PC. So what's the point of the app? To waste my time of cours

It's keeps prompting me to sync and the memory is full. I have tried to download the new firmware and keep trying to sync but it's impossible and keep asking me to try it again n again n keep unsuccessfully. I don't understand why this watch sync n software are so lousy.. my friend experienced the same issue as me. The help desk will only keep repeating asking us to retry over n over again. It's didn't solve our issue at all. Even after download the new firmware, sync didn't able to detect it at all.

Sync problem on my Galaxy A5 2016, android 5.1.1 says try again.

dont waste your time and money

It works well now after its sudden crash yesterday (error message: ppl can't log in the app via smartphone nor labtop). Thanks for the prompt action!! ;-)

I bought the Zefit device but I am unable to register it on my phone. Either it displays a connection error or it does nothing at all. Whats the use to have a smart watch, but I cannot even change the time without the APP. Such a dissappointment!

About a year later and after I lost all my hope for ZeFit it to work, the last update it made it work and it can sync and it's useable! So props to them for that! :)

I have updated my zefit with the latest firmware. However, it always has problem syncing the data from the watch to my app. Anyway to solve this?

I can't connect it to my galaxy s5 and every time I try to connect to it through the app it doesn't work and I tried to connect it my to computer but it doesn't recognize it and it says it's charging.

Changed from one stat because servers where offline. Will update if I find this any better.

I cannot get it to link to my Samsung S6

It's disgusting. I can't even sync watch

Worst device ever

Cant change the time format

Do the job for a nice price.

I have persevered with this app and my watch for about a month and I've grown to love it I realise the problem was that I have to uninstall the app reinstall it and update software every couple of days which is ok if you're running it on Wi-Fi could get a little annoying if it's using your data great app but need to sort out the software problem

The watch wouldn't connect to my android device at all. My phone can't find the watch's Bluetooth device though the screen of the watch was lit and my phone's Bluetooth was on and visible. Followed the steps exactly but still wouldn't connect. Love the watch's design and i would use it on its own but I don't see the point if the app doesn't work at all. Help fix this please

The last update that was in Jan 2016 fixed the issue with sync. I'm happy that I can use the watch now. Keep up the good work.

The application do not work properly. It crushed a million time until now and it's keep showing : [9999] Error! I've been loosing all my data because the application isn't work.....

Had this thing less than a day and I'm thinking of taking it back to the shop and getting my money back

The last update is junk, i'm on my wi-fi and tell me to check my internet connection, for this 1 star

Just got my ZeFit and it doesn't work to pair it on my Motorola Moto X Pure Edition (Android 6.0).

Worst app on the entire galaxy

Software improves the syncing

I'm so upset, i have tried to sync since 6 mo ago, til today Nov, 06 2015 I still cannot sync it, even I can't change the time. No software development from Mykronoz/zefit team, I believe all the problems written here are about sync issue. So i beg you please to fix this bugs.

With this program it is just an overpriced digital clock. What's the point of the sleep tracking if after syncing you can't get any data?

So much syn problem. Worst. Try to update watch software but no pc unable to detect watch!

I've downloaded the app on my samsung s6 edge. Everytime I try to sync it, it tells me to light up my zefit watch then my device shows it's syncing, but would always end up saying Try Again.

Sync fails too many times via ZeFit app!

Do everything written on screen and troubleshooting page, but there's still no signal from watch. Price is low, but it is too expensive for useless toy. Battery life is around 24-48 hrs (not 7 days as claim), even it sits on the table for a day. Worst quality product I've ever purchased.
