DayBand

Very inaccurate....on top of all that at least 33% of the time the app doesn't sync to the watch so app readings don't even match the watch reading. Also highly at random whether the sleep app is going to work on any given night. Sometimes caller alerts will work sometimes not.The only thing that works 100% and accurate is the watch alarm. They really need to do something with this app...like get rid of it and start fresh!

Works but doesn't! Time, HR, BP seem to all be in line. But steps and sleep are way off, sensor counts steps by waving your arm & sleep/awake times are just wrong. Can't get phone, apps, standup, photo or messages to work. Connecting to app, but not Bluetooth. Needs more work but for the value, good to use for it's basic features... HR, BP, time, weather.

The tracker seems to work well. Still learning how to get around the app and device. Not having any issues with the sleep part. The pulse takes a few seconds to come up and so does the BP, but that is to be expected. Would like to have a choice for tennis. Three days now and liking it. To sync the app/screen pull down on the today screen. One more thing don't depend on any device other than medical grade equipment for your health. This tracker is close, but not perfect no tracker is.

The app is pretty dysfunctional, very difficult to sign in. The watch itself does not work very well. The heart rate appears to work fine, but the blood pressure reading usually times out before registering and the O2 results are suspect. The controls are so small that they are difficult to use quickly. It's great idea unfortunately it fails to deliver. Give it a 1 at best.

Seems fine. Had it a few days and most things seem to work. Sleeping hasn't been recorded though. Not too sure how accurate the BPM is but it doesn't seem wildly off. Would like a little more customisation when it comes to the length of notification buzzes. For example to change the SMS reminder to more than just one buzz would be nice. All in all the app seems fine for what I paid for the watch I got. I got my money's worth and nothing more.

I bought two of these, and so far so good. The set up was a little tricky, but with a bit of patience and rebooting they're both all good. It was easy to change the time, once the app was in use on the phone. We went on the same walk to test if the km's were working in sync and they were. I'll be very good value if it keeps working as it is at the mo.

works well for steps, workout, heart rate, blood oxygen. blood pressure isn't auto like you can set for the others. your phone will go off if you go more than 10 feet from it even after turning every notification off. if you like to be constantly hounded that basically have to hold the phone or have it on you at all times it is great. however because of that annoyance is the reason for the rating. fix that and i'll change the rating to 4.5. fix the blood pressure auto set and you will get 5.

DON'T BUY THIS! I bought three of these...one each for my sister and I to become familiar with, so we could give one to our disabled brother who has epilepsy, to measure his blood-oxygen. I didn't do due diligence and read the app reviews...more fool me. The CAPTCHA requirement is beyond stupid - there is NO explanation of what to do, and I only happened to see the email with the verification code when I checked a different device. The email never came to my laptop at all, and they only allow 60 seconds to receive the email, enter the code and write in your password (twice)...and if you take longer, you have to re-send the CAPTCHA. After all that, I finally got myself registered, and looked at the settings on the app. It told me I have 90% pulse-ox, and then about a minute later it said 97% - which is right? Probably neither, judging by the reviews here. Worse, I can't pair the device with the app, which means I can't set the time, synchronise steps, or record the health data which is the very reason I purchased the device in the first place. Have re-set it. Have turned off and re-started the app. Have turned off and re-started the phone. Nothing works. Worst waste of money I have flushed in quite awhile.

I've only just started using this device and app, and it seems promising! My only issue is that I found the incorrect English to be somewhat off-putting; it reminded me of something you might see in a spam email. I would recommend hiring somebody who can proofread all the English translations, to make sure it all reads well and communicates clearly!

The device is great. The app fails it. For example, the body temperature warning starts at 37.3, but I would like the limit to be 36.7. Why? Because wrist temperature is 0.4 colder than actual body (forehead of ear) temperature, therefore it needs to be set lower for an alarm to actually make sense. Similarly, O2 has automatic testing, but no alarm. Why? These are two simple software issues that would make the entire package much, much better. Device is great, app could be 1000 times better.

The TIME of the watch loses time every so often. The problem: simple charging does not fix the issue. The watch is really too wide for my arm. I would like to see a smaller watch on my wrist. The SLEEP part is not actual. Sitting still watching TV is considered that I am sleeping if I am watching TV in the evening. I find the heart rate, BP, and O2 parts are all accurate. Thanks for making a good product.

The app itself is good, however it could do with more features, like cross compatibility with my fitness pal, an adjustable profile which has the ability to measure weight and height and accurately tell you how many calories you are burning versus generic calories. There are some features which feel like they are lacking. Adjustable clock faces would also be a great feature rather then the generic 3 on the korefit.

I had only one problem. Add 10 to the bottom blood pressure number. But what do you expect it doesnt inflate like a real blood presure band. All of this about the AP. Is wrong you can get it to change from metric to american etc.. if you play with it and have any experience with APs. Just touch everything you dont like and you might be able to change it. Then if that doesnt work go through the settings till you figure it out. Im impressed this thing does what it does for what I paid for it.

It works very well paired with the band, but there are some errors in spelling within the interface. When my heart rate hits over 114, it states I am in a fat buring mode. Buring in not a word in my dictionary. I tried to look it up. It would also be nice if this could connect to other apps to share the results between them. Thank you.

The tracker itself is good however the app is awful. Since the last update I have not been able to log in. If you can't log in the tracker loses time and i have noticed that without being able to connect to the app the step count falls off as well. For those having issues with the bp feature if you are able to login to the app and check the bp from therebit starts working on the teacker again. It messed up for me last update. I have tried everyrhing to get this to work again.

This app really needs an update. Sometimes when I open the app to sync it with my watch certain things just don't pop up, or it takes a ridiculously long time to sync. On top of that there's still no blood pressure option put back on, even though when you Buy the watch it says that there is. It feels deceptive. On top of it all the watch doesn't lock at night for Do Not Disturb, so my watch will randomly light up and wake me up and change the clock display. The Watch is great the App is NOT.

Someone should set up a forum somewhere for this app so we can assist each other. I can't vouch for the accuracy of the BP and BOL but the rest of the features are working very well. I got this watch to replace a Striiv that became useless when the company went out of business. Once you get the captcha code(hint -check your junk mail) you can customize the app and the watch very nicely. Sleep originally didn't work but lately has been quite accurate. The message and phone call notifications are useful too. I wish the app would show the BOL history as well as be more flexible on the sports choices. For those of you trying to reach Koretrak look up Korehealth for assistance as they are the parent company.

Doesn't do the one thing it's supposed to. I got this app because it is THE ONLY way to connect to a koretrak watch. It doesn't even do that right. Refuses to connect to the watch. Keeps telling me to move the watch closer, but when you set the watch on top of the screen after the 50th time you've tried to get it to sync and it tells you to move it closer, your app is trash. Do not waste your time with this app or any koretrak products.

Complete junk. I have downloaded the app which has no guidance. Apparently (as I found out from these reviews) when trying to register you must press the Captcha button, receive an email with a code and enter the code twice within 60 seconds. Even under the best conditions my emails take minutes to arrive. In other words this product is unusable. Don't buy it.
