Perfect activity tracker except SpO2 sensor
The device tracks my activity very precisely and accurately. SpO2 sensor is disabled in Japan version of vivosmart due to local regulation. So I purchased a world wide version.
I have medical grade SpO2 sensor and compared the accuracy with vivosmart.
The medical grade one never show below 98% unless I go to oxygen lean environment such as mountain but vivosmart reports 91 to 96% value. It seems like the result is almost random. Unfortunately, I should say the accuracy of SpO2 sensor on this device is poor.
The other functions works perfectly.
I like this device.
