Zhizhi Smart Watch for Men and Women: Bluetooth Activity Tracker (Make/Receive Calls) Waterproof Smart Watch for Android Phone, iPhone, Digital Sport Watch, Healthy Sleep, Heart Rate Monitor, Pedometer
I admit that I am obsessed with smartwatches, especially the "cheap" ones. Zhizhi is the fourth device I've bought in the past three months, and I've been pleasantly surprised by how well it works, especially its accuracy. I've found that these smartwatches from other manufacturers behave differently depending on whether you're using Apple or Android. I have the advantage of trying them on both platforms as my work phone is Apple and my home phone is Android. Some of the app's features work better on one or the other, but for this review it's limited to Android since that's my main phone.
As long as you follow the instructions correctly, the Bluetooth connection is very stable. I can have it in front of my house or downstairs and it always stays connected and functional. Once you are out of range and reconnected, it will take about 15 seconds. Normally it won't reconnect with another smartwatch or two or have to be re-paired at any time. The screen is very sharp, easy to read, and responsive, and the fonts used look expensive. The connection options are the best and most functional I've seen so far. Zhizhi is the only other device that can display the time, date, heart rate, calories burned, steps, and current weather conditions without cluttering the screen or appearing visually "tacky." Making/receiving calls from the watch works fine and is noisy, but you may need to hold the watch close to your face for others to hear. The weather forecast is simple but accurate. Displays the current temperature and conditions. My other watch shows a five-day forecast, but it's not accurate. The blood oxygen readings are so accurate that I compared them to my own fingerprint scanner and they both give the same results. The sleep tracking is really good, the watch knows when I get up to pee and when I go back to bed which is scary (hahahaha). To get a rough estimate, the measured values seem acceptable, and it would be better if the app allowed increment adjustment like my other watches. Blood pressure all i can say is that Zhizhi is one of the best bars around and here's why. In the FitCloudPro app, you can calibrate it based on accurate readings from a blood pressure monitor on your wrist or arm. To do this, click on the "i" in the application. Click your name or surname above. Scroll down and enable Private bookmark mode. Then set SBP and DBP to the exact readings for your device. After I did, the watch's readings were within 5% of the Omron upper arm blood pressure monitor. That's pretty unheard of in a $30 smartwatch. There are so many exercise modes to choose from that I can't comment on as I'm only interested in the steps taken when walking.
Notifications are great and I should add that FitCloudPro allows notifications from just about anything if you want to. Go to Devices > Push notifications and scroll down to More notifications. Here you can select any app you have installed on your phone as well as the default apps listed. This is useful if the specific app you're using isn't listed. FitCloudPro also has a dark mode! Lord Jesus and Holy Son Jesus, why is this option not available in other smart watch apps? It's easier to read than any other smartwatch app has, kudos to Zhizhi! The only small problem I found with FitCloudPro was that I couldn't get it to automate. It's okay, there are many free autoplay apps on Google Play.
The Zhizhi smartwatch can do a lot, but I just highlighted a few features that I think set it apart from other watches. The only similar watch that isn't a blood pressure monitor is the Deeprio Revv, which provides quick text responses on Android. Everything works fine except that sometimes the weather forecast can confuse your current GPS location. I was so impressed with the Zhizhi smartwatch that I bought a second watch in case it ever broke or broke.
