Not my experience, even before the Google acquisition. Phone or chat support never know what is going on. I got the devices based on the advertisement that they provided SpO2 readings so that I could follow same. Only to find out that they really don't. Who knows what the charts mean or if the multi-hour average has any meaning at all. The only way to check the accuracy of any fitbit reading is to compare a real time reading to same from a medical class device at the same time. I can buy a Chinese knock off that reports too but the values have no connection with what my body is doing.
Taking the leap of faith that the fitbit devices ACTUALLY measure hemoglobin saturation through color shift, there is still nothing provided through the devices to gain the value advertised. From my start with the devices, I have posted a request for real SpO2 values on demand. I have received numerous votes in agreement but there has been no movement forward on the Charge series in over 2 years. In fact, now, we are experiencing a backward movement.
I was responding that roll back is not an option. I had a pebble that I could roll back to but it failed and I had to have it replaced, again. The replacement had zero for oxygen readings. The ONLY option was to update again (my existing Android version worked in fitbit's limited fashion on the previous pebble) to trigger an update to the pebble. I was offered no alternative to get access to O2 readings. I already have had to replace my phone to work with the app. Enough is enough. The purchase of these devices is to obtain a service. Not for us to be slaves to programmers that can't get their act together. For less money, I will be able to buy new devices that actually meet the FDA standards for measurement of BP, HR, SpO2 and ECG. They are not as convenient, but the ACUTALLY PROVIDE REAL WORLD RESULTS.
