I've been tracking the CGM watches for a while (to monitor my glucose while fasting), saw that Apple's Tim Cook announced it a few years back but never came through with the goods, have been seeing these advertised on AliEx, and decided to bite the bullet on this one. Couldn't be happier! Not too sure about the CGM tbh — I did test it against a finger prick one at a clinic, and it wasn't too far off — but the other gauges — pressure, oxygen, beats, temperature… — seem to be accurate enough. I have a few $7 FitPro watches and bands I tried before, and the gauges weren't too shabby either — probably the very same components — but the big difference is the screen. Bright as ever on this one, and proper touch too (whereas the others are unreadable under direct sunlight, and the sensor is a photoelectric cell at the bottom of the screen working as a mechanical button). At this price it's a bargain! I actually paid more for it — some $30-somethin' — and noticed the price drop when going back to buy one for the missus (it does fertility cycles too, presumably using more than just the calendar).
Note: This watch may not provide accurate sensor readings according to reviews on Amazon and should not be relied on as a medical device.
Hi OP
How much was not too far off for the blood glucose levels? It looks interesting though. What app does this phone use?
