Hey everybody, Brock here, and today I'm going to tell you about this little guy.

It's called Tink by Zenzorium.

It's a little tiny, let me take it out of the fancy little box here, it's a little tiny

up a bunch of biofeedback from your body.

Now the four things that this little guy does is it picks up when you put your phone

and your heart rate variability.

Now it's pretty easy to tell how it does your heart rate.

There are a lot of apps out there that just use the back of your phone and you put your

finger over top of it, it shines light through your finger and it can detect the beats

of your heart and the movement of your blood by the density that's color changes beneath

your skin.

I have no idea how it's doing that.

In fact, one time, twice now, actually I've put my thumb on it and I've gone for the

entire time it was taking the measurement which actually was quite difficult and I almost
