RE: This Smart Fitness-Tracker Comes In Form Of A Ring!
I dunno about 'fitness tracking'...I could use a real time BP, Blood Sugar, Blood Oxy Level, Heart rate, etc monitor though.
maybe some more functions would be nice.....enough to spot a trend.
True, it's quite limited only collecting data from your finger.
But it's a good start, maybe we'll see more function for fitness wearables in the future!
