DayBand Customer Insights

1. I'm sorry, but if this doesn't start working, I'm going to have to return the watch and get a different system altogether.works well for steps, workout, heart rate, blood oxygen.

2. The heart rate appears to work fine, but the blood pressure reading usually times out before registering and the O2 results are suspect.

3. Heart rate doesn't work, blood pressure doesn't work.

4. I will keep it as I have already spent money and it started crashing a day after I could return.I can't figure out how to get the sleep tracker to work 😫.

5. fix that and i'll change the rating to 4.5. fix the blood pressure auto set and you will get 5.The band is too difficult to take apart for charging; and the angle of the USB male makes it difficult to charge correctly.

6. When you take a continuous heart rate reading over any length of time and then try to look at it, you are only able to advance the result time line by a minute or so at a time, so if you do an hour or more reading, you will be swiping for ever and ever to review the whole period.

7. Vitalwatch reviews were good? It won't do a main functionality??? Someone want to save it from the landfill?The tracker seems to work well.

8. What's the point of having something that only works when others want it to work, and not when you need it to work.

9. The KoreTek watch works fine, but what's the point of having it if I can't track progress? I've uninstalled and reinstalled the app and still got nowhere.

10. I'll have to pay more for something that actually works.Well, got this band to get in better shape and 2 weeks in the app won't synch and keeps crashing which is kinda defeating the purpose of having this thing.

11. Update, Customer service sent me a link to a manual which mentions nothing about sleep tracker and will not zoom large enough to read.

  • Cannot register. I received a number 810604 but it goes nowhere.

    β€” by Gwen Smolik 3 years ago

  • I purchased 2, only one worked. Tried numerous times to get second one working, but, would not even charge. Koresupport sent another tracker, supposedly free, but, I told them sending it back.
    The one that worked was fine, not very accurate, but for the price, okay, despite the tracker to phone binding does not always work. Threw the one that never worked in a drawer, got banged around, dropped... Tried one last time to try and charge it, and lo and behold, it charged. Gave to my husband, as he tried the first one and liked it.
    Now I'm trying to bind the tracker to his phone. Not installing. For some reason it's messed my phone up and I can no longer sign in or get a new passcode. So now both phones not synchronizing, letting me sign in. Oh my God! Somebody do something, please. Help me at least get the one that originally worked back to binding with my phone

  • I reported that I can't register my KoreTrack watch on January 3rd. The app is asking me for a password and it won't accept any. I purchased this watch on September 12, 2020. I have been trying to get it registered since sometime after that. Nothing will work for me with DayBand. I have requested help with setting it up and no one from DayBand will help me. I don't know what password it wants in order to set it up. This is very frustrating. Please have someone reach out to me with the password that I need in order to help me set up my watch. Thank you.

  • I cannot connect koretrack to my smartphone. I need EXACT steps on how to do this. For example, what does GET stand for when i try to register? I assume that it sends a code to my e-mail that I am supposed to enter on the Captcha line??? Is "Bind Bracelet" on my smartphone or the koretrack itself?? I am computer literate but this set up is very user non-friendly!!!!

  • Haven't gotten any sleep numbers in over a week. The app stopped giving me reminders to get up and move over a month ago.

Wore the watch exactly where specified and after two nights I still have no connection between watch and cell phone. I have gone over and over the steps to make this work. So you tell me. What is the problem? I have even deleted the dayband app and set it up again. Same results. My wife and I bought four watches and I would prefer to keep them rather than send them back. You give no good explanation as to how or why the sleep mode should be set up to work. Enlighten me. Thank you
