Smart Fitness Tracker Watch with Heart Rate, Blood Pressure, Blood Oxygen Monitor & Step Counter - Activity Tracker for Women & Men - Compatible with Android & iPhone - Perfect for Running, Gym Workouts & Daily Health Tracking

This is my second Yihou fitness tracker. The first one was the first fitness tracker I have ever owned. I set that tracker up, incorrectly apparently. I could not get it to adjust to the correct time or date or change from military time. I was also confused about which app I needed and how to get it. I did not want to download the wrong app and possibly have security issues. With help from the community I finally realized I needed to scan the QR code in the booklet that comes with the fitness tracker using the scanner in the wallet app on my iphone. I returned my first fitness tracker to Amazon and wrote an unfavorable review of the tracker.Yihou Fashion reached out to me and provided more detail on how to set up the tracker and asked if I would try the tracker again since I was still in the market for a tracker. First I would like to apologies to Yihou for my edited initial review and thank them for their great customer service. Second, I would like to explain what you need to do to get the most out of this fitness tracker which is a great value for the money. I am assuming the people who wrote the instructions for this device speak another primary language because there is a little something lost in translation.I would suggest going to the app store and downloading the required app, “Da Fit” as soon as you order the tracker. Alternatively, you can wait until the tracker comes in and scan the QR code on the first page of the booklet using your phones scanning app.Before you do anything with your phone's blue tooth however, go into the Da Fit app you have downloaded and enter your info (height, weight, age etc) and allow the access you would like to share with the tracker. Where I made the mistake the first time is connecting the tracker using my phone's blue tooth. Initially the time and date were right and then they were not. If you set it up using your phone’s bluetooth settings, you will have problems with the date, time and probably accuracy of the fitness readings. You must synch the device from the Da Fit app not in your phones Bluetooth settings. If you do this, you should not have the problems others have complained about regarding the time setting, especially the 12 versus 24 hour setting. Downloading the app and setting the tracker up through the app is really easy. When I got the second tracker it took less than seven minutes to set it all up since I already had the app downloaded on my phone.I have been wearing the watch for almost a week now. I wanted to wait a few days. I wrote my first review of this watch after wearing it for a day. As I said, I ended up returning the first tracker disappointed after about two weeks. Then I edited my first review to something unfavorable. It was all my fault because I set it up wrong. This time, it is holding the time and date. It is showing regular time versus military time which you can change if you want in the Da Fit app. It seems to be tracking my steps properly. The heart rate and O2 sensor seems fairly accurate also. I used it to click the shutter of my phone’s camera and I have received text notices. I don’t really want other notifications coming to the tracker but you can allow more in the app if you choose to.I have used the BP which does not seems accurate compared to other devices I have to measure BP. Honestly, I think that is an ambitious ask for a device you wear on your wrist that cost $40 and does so many other things. Having worked in a hospital, I have gotten various BP readings from devices costing much more with one of their primary functions being to measure BP based on different body position or too much movement. There are variables involved with BP that could make it difficult for any device like this to capture BP with great accuracy. I am not overly interested in this function of the tracker.Navigating through the tracker’s functions takes a little getting used to. Unlike other mobile devices it does not have a touch screen although it looks like it does. With the tracker on your wrist, you touch the bottom left corner of the tracker to bring up the screen. Touch it again to go to the next function screen. Touch and hold the bottom corner of the screen to go further into a function. Also with the tracker on your wrist, just turn your wrist to look at your watch the way you would normally and the time and date screen come on automatically. Very cool! After a very brief time it goes blank again on its own.All in all, I am very satisfied with the tracker, especially for the price point. I think it is a tremendous value for the price. It does a few other things if you are interested but all I really wanted was a time piece, and step tracker. The O2 and heart rate functions are tremendous bonuses. They seem quite accurate. Furthermore, I find the tracker quite attractive and comfortable on my wrist. I am not a big fan of jewelry of any sort on my body. This is the only fitness tracker I have ever owned, so I don’t have a lot to compare it to. I do not have much disposable income, so I thought this was a safe investment for my first fitness tracker. I love it, and highly recommend it if you’re the average person looking to try a fitness tracker.
