I received a Dayband watch as a gift 2 years ago and it has worked great! I went to charge the watch yesterday and it will NOT charge. I have tried several different charger units that are working with other devices but I can still not charge the watch.
It's not tracking my sleep. How do I fix it?
I love my day and watch,as I use the BP, HR,etc.functions; however, the resetting, unbinding isn't working. Please help!
My dayband won’t connect after it gets about 2weeksdatotheonlywaytosutwstchofftoresetitiostoletbatteryrundown
My day and watch back is sticky and coming off. What can I do?
Wrist band has broken. Can I get a new one???
How do I change the Celsius reading to the Fahrenheit reading?
I got this Smart Bracelet as a gift. When trying to register it, I pushed the Captcha button several times, not realizing it was sending me an email with a code each time. Apparently I maxed it out and am now locked out. It's pretty generic. There is no model # or serial #. Can you please reset it for me so I can register? Thanks for any help you can give.
After three years of daily wear, the bracelet is tearing and I need to buy a new one. The watch works fine. Where can I buy another bracelet for my Day Band fitness tracker?
I purchased two dayband watches from you less than one year ago. I also purchased the insurance which was suppose to be for lifetime of the watches. My problem right now is that the watch that I have been using does not charge. Previously I had to plug it in two times a day to keep it running. This morning when I put it on after my shower, it didn't do anything. I tried to activate it by tapping on the spot but nothing happened. I don't think it charged or will charge, Please advise me what to do. I like the watch and the various functions. Thank you
my watchband is starting to break can i buy just the band
My partner brought me a dayband the first night i wore it it tracked my sleep now for 3 nights nothing i have just read all the chats seems like my partner shouldnt of brought it. Please tell me how to track my sleep, apart from that everything seems to work fine,apart from i cant log in either 😡
I ordered two watches from you on around March 10. 2022, and $109.93 was taken from my checking account. On April 10, 2022, you took another $39.99 for some unknown reason, and I request that the money be returned to my account immediately. Respectfully Bill Franklin
I bought 2 of the daybands. My mom put hers on charge then lost the band that goes back on the watch. How can I get her another band?
Your product is very poorly designed. Stopped working appropriately after several weeks. No longer counting steps. Can't get customer support without paying for it. Will highly recommend to NOT purchase this product.
Would like to shop for a new watch band
App will not install on Android 11 device. Device reaches the app page, but there is NO install button. Instead, there is a message that it is not compatible.
Can register as the captcha does not provide with further details and can't progress to registration
Can't register
my watch seems to be working just fine for now but it comes with different watch faces and i dont know how to change the watch face on mine...i saw three different ones when i first got it but now i cant seem to change it. plz help
Cannot get blood pressure or heart rate. Everything else is fine.
cannot register, date and time wrong cannot change watch is useless
I cannot open an account with the dayband app on my android phone. It keeps failing. I have completed the dodgy captacha for which there are no instructions so unless someone wants to address this problem now I will simply send the thing back to amazon for a refund. so dissapointing
My Dayband stopped monitoring blood pressure. This function was the reason I purchase it.
Purchased a new android phone. Can not pair the watch with new phone. Opened a 2 hour chat with Ella (your service chat person) and could not resolve the issue. Ella offered a new watch to replace the watch we can not pair. I needed to get the Amazon purchase information to do that. I now have the information and need assistance.
My Koretrak watch in the last month , after a full two hour charge , only lasts six to eight hours , which I am sure you will realise is really inconvenient . Can the battery be replaced , if I send it to you ? (Please supply me with an address if you can mend it ) I hope you can help me , Thank you .
For some reason my app has logged me out and I can't log back in, nor can I reset my password. It renders the watch totally useless, as I've probably lost the last 3 months of tracking data.
My and my wife's Day band stopped giving blood pressure. Units were specifically purchased for this. How can we have this application reloaded or where can we return these devices. I feel we have been duped by false advertising!
Been locked out of the app. Also now forgotten password
Blood pressure stopped working. Can't get it back. Now what?
Hi I've been using my replacement Koretrak ( first one didn't charge ) all is good now except I'm confused about my login - The watch doent recognise my login email or password and I'm unable to reset it - I've tried dozen of time -I've tried uninstalling the app and reinstalling with no success! Can I do a factory rest? and just start again Darryl
can't login, email doesn't register
I cannot register my koretrak pro. Cannot get sleep function to work.nothing works properly. How can I fix itCan I return my product? I purchased 2 and the warranty. Can't register that either.
I cannot log into my app on my phone. It keeps telling me my email is wrong. I have tried to different ones. How can i reset/change my email address?
This thing is a nothing but Junk. can not get it registered , sent them a email and still have not heard from them going to send it back do not buy this KORETRAK DAYBAND took 3 hrs to down load to my cell
I just received mine two days ago. I agree on the sleep recording...does not work. Maybe a firmware update someday? Regarding the captcha: Was "unusual". You (or at least I) couldn't get it to fly on my phone either. If you can get to a point where you obtain a small circle counting down from 60 seconds on the captcha entry line...CHECK your email. The email address you used to sign in/create and account. They send you the captcha....its a 6 digit code they are looking for. I didn't play with calories or sports watch. Temperature, heart rate, oxygen, steps and time (lol on time) all seem accurate. I tested them all against an Omron Wrist Series 7 blood pressure unit, a Kardia EKG device and a Walgreens Pulse Oximeter. For the money it suits my needs. How long will it work is yet to be determined.
Biggest problem I have so far is that the sleep tracker has not tracked anything... That's the main reason I am wearing this thing. Also, I cannot register because it asks me for my email, Captcha, Password, and Confirm password but there is no captcha present for me to type in.
Much like everyone else here my KoreTrack only occasionally records my sleep and the blood pressure is a joke. It is way off. Buyer beware. I should not have cheaper out and went with a higher priced and better product.
All my functions on my Kore trak work except the sleep function. I have reset the watch, uninstalled & re installed dayband. Unpaired & re paired to my phone. Switched my phone off but nothing happens. I am disappointed as I bought the watch to monitor my sleep.
I bought 2 watches, received a few days ago. One of them indicated that it required a firmware update. I started the update and was informed that it was completed successfully. Immediately the watch would no longer connect to the app and indicates a dead battery. The watch is dead and will not recharge. Could you tell me how I should return the watch.
I have a Koretac, smart watch that has been great until today. I took the bracelet appart to charge the watch and the conyact buss on the buss came off and is gone! the watch is only a couple months old and should not fail in this manner. Please advise your action to correct this problem. THank you!
I payed for this watch a couple of monthes ago now it does not turn on or charge at all no numbers to call does any one know were to get a good number to call
My Kore-Trak watch is working perfectly - except for the sleep function. It has not recorded any sleep data (I've been wearing it a few days now). Every other function working fine, and I'm able to log in, etc. A little disappointed, as the sleep tracking function was the reason I got the watch in the first place.
Piece of S#!+ ... Well orchestrated scam. Same issue as everyone else can't register as catchall is a joke. Most functions are fictions. Lesson learned.
Why cant i register my watch 5th time i have emailed you.
It looks like we may have duped! The product you purchased may be a knock off of a product called KoreTrack https://www.korehealth.com/performance/koretrak-smart-fitness-tracker.html Their customer is great and you can chat or call them directly. They also have a YouTube channel https://youtube.com/c/KoreHealth Watching their videos will allow you to compare what you received to their real tracker. Most often the interface looks different and some features won't work. The biggest deception is that it uses the official KoreTrack app 'DayBand' The knock off company would not respond. Mine was sleeptracker@redacted.
My first kore track/day band had an inaccurate heart rate now the second won't track sleep 🤦 Very disappointing!
I cannot register with the Dayband app on my android phone. If I cannot get some help I would like to send the device back and receive a refund. After reading all the information about the Koretrak I was excited to receive and start using it, then I cannot even register to get started and then read all the terrible reviews. I am so disappointed. I feel like the advertising was very misleading.
I rebooted my phone and now the app tells me I don't have an account. I got a verification code at one email. But my phone seems to think it is a different one. But my app says neither one is right. I kind of like the app and the watch, but not being able to get to my info is pretty frustrating! HELP!!!
My watch does not keep accurate time. It looses time like 8-9 minutes every two weeks. Also I tried to get into day band app and I get to part they want to set up jogging part I don't want it. Can't go any further to reset the time.
unable to register device on an iphone using dayband, app sees device but gives no option to bind. unable to even change the koretrack time setting to the correct time, with or without the phone app. manual does not include much on anything
Blood pressure reading way off. Oxygen reading is not correct. Does not record sleep.
This day band tracker is garbage!! Won't charge batteries. I want to return and get my money back. Pls. Reply as soon as you can.
I can't get captcha
Not getting any sleep data. Also can not register.
This watch is junk !!!
This is my 7th day using this watch and it simply will not register my sleep and that is the main reason I bought it! Have tried contacting Koretrak directly, but they won't respond! Please fix the sleep function! Also steps on watch are different than steps on app. The app won't display the current weather conditions either.
Can't register. Captcha doesn't work
I cant get the sleep to register
This is a mess! It is not user friendly. I have been able to get this Captcha code for several days, and can't contact anyone to assist. You tap "GET" and you get nothing. It is not easy to maneuver through the settings. This device is not attentive for desired needs.
Can’t get sleep mode on watch. Sometimes records sleep only to my iPhone.
I was stuck at the captcha too. Turns out it was easy. Give it a valid email address and it emails the code you need.
I have a day band watch for less than 6 months and it will not charge. I have cleaned contacts, but this does not help. Please advise how to fix or replace band.
I have a koretrak that will not switch on. It wont even charge. This was only purchased in November, and after 4 months it has packed up. I need to know how to get the thing started again and how to re-sync to my iPhone (which it wont do as the watch wont bloody charge). How do I get a replacement watch as it is under 12 months old - or a refund please.
I purchased this tracker after reading all the wonderful things it is supposed to do. Installed the app on my Samsung, but like everyone else I cannot login. Also, the clock face keeps defaulting to the original and I know the steps are way off because I also have a Fitbit one and it is way more accurate. I also think that it sucks that there is only an Android app as I have some older friends that purchased the Koretrak and since they do not have cell phones, they can't install the app to do any of the set ups. There needs to be a windows based app as well. Also, there is absolutely no tech support from Koretrak as I emailed them when I first installed the app an no one ever did reply...company sucks!!
It is not recording my sleep. Also it is stuck on the voicemail screen, and I cannot get it to advance. Finally the time is wrong and I can't figure out how to change it.
did connect to phone but now doesn't. can't log in
Blood pressure is so far off it's ridiculous. Will give you a false sense that your blood pressure is fine. I stopped taking my medicine because this toy said it was OK. Bad move!
The Dayband app does not let me register on my Samsung A51. I got the Captcha code but “Get” doesn’t do anything.
Just found my Captcha code!!! It was in my junkmail with all my other attempts to get one!!
Can‘t sync watch to Smartphone A51. Time Shows incorrectly. Cannot read Information- Not Even with reading glasses. Fell prey to same fake great reviews as everyone else. Same issues, same troubles! Bought two! How do I get money back? Paid plenty of customs charges in addition to watch price on top! What a shamer! Please advice and appeace. Cornelia
My dayband won't charge in any of the USB ports I have in my house, laptop or any phone charging devices. Suggestions?
How do you set the time and date?
Dayband won't register. How does the Captcha work ? Absolutely no instructions on how to register. I have tried every combination and have received the verification code by e-mail at least six times but it simply won't connect or GET . Blood pressure and oxygen readings have stopped completely after a few days of use. The watch paired to my Samsung phone several days ago but has disconnected and won't reconnect. So far I have a watch with print so small that I cannot read anything on the main face except the time (even with my reading glasses on) and virtually nothing else. I bought three of them but had so much trouble even trying to understand the initial set up that I haven't opened the other two. A waste of money for what appears to have generally decent reviews in most places. WHEN IT WORKS, I can see from the numerous comments over the past couple of weeks that Koretrak suffers from severe and very common identical faults and complaints in respect of registration and pairing..
I cannot register an account as the ‘Captcha’ setting does not seem to work. Why is there no instructions on how to use this function? I can see that hundreds of other customers have the same issue.
Can't register, can't get captcha to work
How do I return this watch Can't get the sleep tracker to work, I don't think the blood pressure is correct compared to my home monitor
I cannot register my watch. I need captcha code please
Finally managed to register. . . . did it through the Facebook link. Not verified whether all the apps on the watch work yet but it seems pretty cool. Just remember that this is a Chinese watch and sometimes their thought processes aren't the same as ours, which is why we sometimes find things difficult. But persevere . . . will update when I've used it a bit more.
The sleep function does not work. I have not been able to connect the watch to my iPad. I have tried to contact Kore Trak twice but haven’t had an answer.
The Captcha option to create a new account does not "GET" anything and will not allow me to setup the Dayband software Extremely frustrating. Please help. I noticed that I am not the only one with this issue perhaps a re-think on you choice of software for setting up accounts.
What is captsha. Cannot login.
What is the Captcha code, I can not log on
PLEASE HELP! I can't register Day Band on my Samsung A21 phone. I can't use my Kore Trac watch until I get the app on my phone and it won't let me register. I've used both my yahoo e-mail and my g-mail and tried 50 times. Please call me at 814-602-4017. E-mail if you must. Just please contact me asap. Valerie LaPlaca
Cannot record the sleep part on this watch. Have tried everything . I think this is the most complicated piece of technology and have been very disappointed. I want to return and my husbands as well so can you please instruct as to where I return them and how soon would I get a refund. I am within the 30 day return guaranteed. We have been very disappointed with them, not at all what we expected and we were really looking forward to using them. The App is not accurate either and not always available. Please get back to me asap thanks.
Where do I get the Captcha from? So far...not impressed at all. The reviews I read were great, but I can't even register.
Can not get the Captcha Code where do I find it?
Sleep time on my dayband app is not registering. Help?
Bought the KoreTrack for $50. Advertised as a great deal! The BP function is way off. The Oxygen saturation function is highly variable. The software that you provide to sync the watch with a cell phone is nearly impossible to sign into. You use the term "Captcha" in the sign in process, which is an obscure use of an obscure term. It would have been easily understood as accessing a code from your email. Very confusing for most folks, including me. Once I successfully created the account, the software would not let me log in again. I have spent hours of frustration dealing with your poor design. Instead of helping me with my blood pressure, it has instead raised it!!!! Enough with the frustration; this watch is destined for the trash bin.
I cannot register my Kore Trak smartphone on the Day Band app.
Sleep function not working. It’s on the app but not recording.
Does not record sleep
My watch wont register. I bought 2 of them. how do I find support and how do I return them if You dont supply support
Having problems like so many others. I have a Koretrak fitness watch. If that what most everyone else is using. In Dayband I selected "Sports" then selected "Walking". One day it did track my steps and distance and the next, NOTHING. Also Dayband is not tracking my sleep and when I select "Continuous Test" for heart rate it also worked one day and the next it doesn't. I am not sure if this is a "Dayband" issue or a Koretrak issue. Now I wish I would have spent the additional money on a Fitbit. .
blood pressure is not correct, can't get sleep to work. Boyfriend bought this for me for Christmas before you sell a product you should make sure it works correctly.
I am having the same problems as others. BP way out of whack, Cannot change temperature, says it's 6 degrees and cloudy but the actual temperature is -2c therefore I don't know if the location showing is where I actually am. Doesn't say what province in Canada it is. Should be Ontario but could be BC so don't know how to check that. Also sleep tracker is NOT working!! I have to login every time with email, p/w and capcha (which is NON EXISTANT therefore incomplete as well, therefore cannot get in unless I like others on here have to try many many times to log in. NOT acceptable. I have been blaming Kore tracker but now feel it is NOT an issue with the product, it's a dayband issue. Tracker
Same problems, if you skip registration you lose sleep information, Captcha has to be completed or your WEEKY info will be blank. Managed to register by repeating my email and password over and over until Captcha gave me a count down, went to my email got the code and entered it before the time ran out,everything now working.!!!!!!!!!!!!! please note , repeat email and password manually, no copy and paste.... it will work
will not record sleep
Cannot register Email address on Dayband device. Cannot understand purpose of Captcha. Seem to be going around in circles
Can not register my watch.

App does not retain data from the device when you have to reset the device, shouldn’t be that way (loss my data four times). While a rep responded promptly, within a day, to issues I was having their suggested solutions didn’t work (Strike 1). I figured out what to do myself. They don’t seem concerned about buyers losing their data, they do apologize (Strike 2). And Strike 3, the company took it upon themselves to remove the Blood Pressure Tracker in the form of a firmware update that both removed it from the device and app. This was a feature that was paid for when purchased. No warning or option to keep it from the company (one moment it was there and upon doing firmware update it was gone). Until they add the feature back in I do not recommend buying. I have been waiting a month to hear back from them about the missing feature, dead silent. Too bad, I would still be using it if they hadn’t done this to their customers. I have moved on to a different company.

I have written this several times now. If you try to use the support under “about” in the app - it crashes every single time! And the support attached to this page is all in Chinese! Utterly useless! Also, the weather displayed has been completely wrong since the day I purchased the band a few years back. I pulled it out recently to see if the recent update they did may have finally fixed it! Of course it didn’t! It has been waaay off since day 1. For example, the weather on the band says it’s 35 degrees F and sunny, whereas right now, it’s 18 degrees F out and snowing! If they can’t get a simple thing like this right, who’s to say the tracker works efficiently at all?! Good luck getting any help or support from them. I’ve tried. Do yourself a favor and avoid buying any of their products and delete this app off your phone! It’s not worth your time and money given the frustration you will inevitably face!

The app is poorly designed. My main problem is the inability for the app to monitor my sleep habits. Many times it tells me I’m not sleeping at all. It records nothing and I am wearing the watch and yes it is charged. Or it will say I went to bed at midnight and woke up at 3:45. When I went to bed at 10:00 and was up at 7:00. If I go to bed at midnight it throws everything out of wack for recording sleep patterns for two days.
The other problem is the motion detector. Even when I’m moving it tells me to get up and move.
This watch/app worked great for 30 Days and now I feel like it’s a piece of junk!!!! Nothing is working. The only positive thing I can say is at the moment it keeps good time. Even monitoring my steps has failed. 🤨
