Review on 📱 2021 Smart Watch with Call, Health Tracker, Sleep Monitor, Message Reminder, and Music Control - Waterproof for Android iOS by Zachary Jackson

Pros: Some sensors are "inside" the target. The blood pressure algorithm is "inside” the target. I tested this with mercury blood pressure, systolic 1 point higher and diastolic 1 point lower. ECG Can't tell right now, but I'll compare it to my appt ECG in a month. Sp02 exactly, I have a machine and it is measured with T. HR is accurate too, I compared it to my HR from my HR treadmill and it was measured at T. I can't say sleep monitor. I was sleeping, who can confirm that. If you can confirm that your sleep monitor is accurate, then you are lying and fooling yourself. The pedometer is accurate. The watch itself is very light, I can't say I'm wearing it. The clock is impressive. I liked the flashlight very, very comfortable. I will tell you about the battery later as I only received this watch 3 days ago. Not making/taking a call is a plus as I don't want my watch to be a phone. Cons: I want to rewrite the date as "October 5th" instead of "October 5th". I wish I could circle the day and not just a faint green bar at the top. I want to be able to choose my app that I want my watch to notify me about. Instead, your own pre-filled application.
