Who Is Using Quantified Self?

Gary Wolf and Kevin Kelley, editors at Wired Magazine, are generally credited with coining the term "quantified self" when they began a project to track all the new tracking technologies.

What is the meaning quantified self?

The Quantified Self movement defines the self-tracking, measurement and quantification of all aspects of daily life using technology like applications and wearable smart devices, such as activity trackers or sleep monitors.

How many people use self-tracking apps?

If you look at current census estimates and the Pew data then we see that almost 35 million3 US adults are using technology to self-track. Of those, 8% use a medical device, like a glucose meter and 7% use an app or other tool on their mobile phone or device. Combined that comes to 5 million adults.
