We’re announcing a new feature….but first, let’s have some backstory and some science!
The back story:
Many mobile phone generations ago, back in 2016, whilst the middle of developing version 1.0 of Virtuali-tee for our Kickstarter backers, I remember discovering that my phone (Samsung S6) had a pulse sensor built into it. Right next to the camera was a tiny little rectangular sensor, it had always been there, but I had never noticed it. It worked almost like magic, by simply placing my fingertip over the sensor the phone took my pulse rate and presented it to me.
