For Android and iPhone 4.

I have no idea how accurate it is, but it operates on the same principle as Nintendo's Vitality Sensor (measuring light passing through the blood in your finger). It was just such a damn clever adaptation of smartphone equipment that I had to post it somewhere.

So can it be applied to games? If not is just one of the many apps used just to show how fucking amazing your iPhone is...and not much else.

While, the only game we know uses VS has an amazing concept...relaxing! Seriously, Nintendo is really trying to make you live with just videogames: you can be an hero, you can play sports, you can relax yourself...I like that!

It was pretty close on my Android.  Listen to the warning though and use in a well lit room.  It was way off in a dark room.

How dare you to play with my hopes so much! >:(

Can it? Well, sure it can.

Will it? Probably not. Though there's nothing stopping these guys from tying it in with some soothing sounds and online leaderboards and calling it iRelax.

But c'mon, aren't you a teensy bit impressed with the ingenuity of these guys? It's not like Apple and HTC and Motorola set out to build heart monitors...

Well-lit? I thought it needed to use the camera LED. Are you telling me they can do it just with strong ambient light?

Not all android phones have a light, mine doesn't.  If you have a light then it might work in a dark room.

That came out of the blue!

Sometimes, I hate misleading topic titles. This is one of those times.
