DR.VIVA Fitness Tracker Watch, Heart Rate Activity Tracker Touch Color Screen IP67 Waterproof Sport Tracker Watch with Calorie Counter Pedometer Sleep Monitor for Kids Women Men

The DR.VIVA fitness tracker watch I received does not work. It powers on but the Zeroner app consistently says it can't connect to it. Without connecting, I can't set the date or time and it will only count distance in kilometers. It had the features I was looking for so I had hoped it would work, even without an app, but as it turns out, it's not usable without connecting to the app and it keeps saying it can't connect.

The digital part of the watch fell out and was lost after 2 weeks. Great product but didn’t last long. My son was disappointed.

Nice fitness tracker, I loved the ability to choose the size and color of the digital display but the band was too wide for me and irritated my wrist so much that I had to stop wearing it and return it.

Very good fitness tracker with enhanced tracking features.Sync to the phone and the readings are very accurate.Very pleased with this product and its price.The battery is too good.

I paired it with my phone and it requested a software update which I did but the watch froze on an arrow screen for the last 2 weeks and wont do anything else. Shameful

I got this in exchange for my honest review. This is a love hate relationship. I love the features and all the different settings but I hate the interface. Sometimes screens scroll super smooth and respond to touch inputs as they shoul and sometimes they wont scroll or lag so bad you want to smash this with a hammer. Sometimes it links seamlessly with the phone and sometimes you canset it on top of the phone and it acts like it has never even haerd of bluetooth. There is no rhyme or reason. I used it in a workout yesterday and part way thru i must have bumped the screen because it turned off the fitness program. Today it would not register i was working out at all. Some of the data is super accurate (im wearing a second fitness watch just to compare) and some is so far off that according the the watch I may just be deceased (not really but i dont see my heartrate reaching 276 bpm just sitting watching videos) The app is ok but does take some getting used to and some stuff that should be intuitive seems awkward and reversed. They use odd terms for certian actions (like to unpair or disconnect from the phone they use the term unbind! ) There are a lot of nice features but are almost to specific (like there is no workout routine but you can choose tenmis, soccor, running, badmiton, basketball etc.). And it stores messages (i thimk up to 5) but if you dont delete them new messages are not displayed only the old ones. The band is real nice and the watch looks like a very expensive timepiece. Charging was straight forward and batterylife was excellent. The watch did get caught in an upgrade loop that kept telling us there was no devise connected. We unbound and rebound the watch and it settled down. There is a lot to do and set with this watch and when it is working it is really nice. Patience is sometimes needed to work with it at times. What i saw and used with this watch I really liked and the app is a pretty good app once you get beyond some of awkward language

This thing is made by iWOWNfit and the app is made by com.kunekt. The model is i6-HR-C. I don't know what Dr. Viva is except maybe a first attempt at branding. There is no reference to Dr. Viva in the app or their website.I am truly impressed with this technology. It is as accurate as Fitbit (don't know how accurate THAT is) and even better on heart rate than the Fitbit Charge HR because it is shaped better to a wrist and the sensor makes better contact. The full color screen that is touch sensitive in at least three points is truly wonderful. Swipe up, swipe down, press the top or center, and long-hold to switch modes and select. The clever case which holds a standard USB port is brilliant and puts Fitbit to shame with their proprietary dongles. And the price is 1/8 to 1/6 the cost of similar tech with in the Fitbit brand. Utterly amazing! God bless China!But there are problems, some annoying, some serious. Most serious is the requirement to use an app on your smartphone - either Android or iPhone.* Like so many apps, you have to allow the app to see just about EVERYTHING on your phone: identity with phone number, contacts, location, texts, photos and media files, the camera, and wifi info. The app requires you to submit to their privacy policy - the shortest privacy policy I ever saw at two phone screens long. Basically says in poorly translated English, it says, "We will follow the law regarding privacy. We collect everything from your phone, the website, and [by cookies] anything you share with our partners." Not sure what the laws are in China regarding American privacy. Presume any picture on your phone will be attached to your name and phone number and sold to other companies as part of "identifying information." Are American companies any better? You be the judge.* After installing, the app offered to update the tracker within minutes of first Bluetooth sync. The App locked up my phone when I made a choice that I couldn't back out of. Poor programming for the install portion. But once working, everthing went very smooth.* The clever internal USB plug can be inserted upside down in a jack. You have to see which way the screen lights up. It's easy to insert and presume it's charging when its not.* The app's poor English is more than annoying. For example, when it says "clock" it means "alarm." The whole thing requires my tech translation skills to navigate. Once you learn it though (a couple hours), it's fine.* I wish you could do basic things like setting the time without the app. If you don't have a smart phone, (or don't want to install the app) this could at least be a fashionable watch.* Another serious issue is that this app will not sync with other health sites like MyFitnessPal (by UnderArmour) like Fitbit, Garmin, and other major manufacturers do. It does sync with Google Fit and something called Strava. Syncing with MyFitnessPal and others like it would sync your biometric data (from the tacker) with your diet info, map data (think running and bicycling), and other devices like the home scale. I mean, Fitbit does it.* Some reviewers might have older versions of this product. For example, one reviewer wrote the watch allows 24 hour military time only. The selection for 24 or 12 hour time was obvious in the app (the default was 24). Another reviewer wrote the app "iWownfit Pro" did not work and said to use one from another company. Actually, the iWownfit Pro app worked exactly as described for me. Several reviewers wrote the manual was too small to read. I have poor eyesight and sometimes use reading glasses for magazines, but I could read this manual without glasses. The print was uncomfortably small, but I didn't need glasses.* The box is pretty plain, but lists these features which demonstrate the translation problem: Battery, Battery life, Input voltage, Protection Degree, Bluetooth, and System requirement. The capitalization in the list is exactly as on the box.I am not a fan of Fitbit. Their stuff is 4x overpriced and the junk breaks in a year. But their phone app is great and website phenomenal. And being the industry standard, their data syncs with all health websites especially MyFitnessPal for dieting. This Dr. Viva item seems superior to Fitbit and is one-eighth the price. Still, you have to think whether the syncing and security issues of Fitbit might force you to choose the more expensive option.

This is the first fitness tracker I've ever used, so I am still figuring out how to use it. The watch is operated by different taps, slides, swipes, etc...and there doesn't seem to be much difference in how those actions work. Maybe it is user error, but I can't quite get it to do what I want reliably. My phone says it is connected via bluetooth, but the app doesn't think it is.. so things aren't getting tracked in the app either. Making the app somewhat useless. I'm going to try to uninstall and reinstall to see if that will help the situation. So far, the tracker itself is ok, the app isn't helpful. Maybe its my device? Maybe its my phone? Maybe its me? Going to work on it a bit and see what I can do.
