But it's not quite as good as star trek, because whilst I have a communicator, I don't have tricorder.
Except, yesterday I downloaded Instant Heart Rate, which is the cleverest thing I've bumped into this week.
It turns the flash on the phone to constant full power, while you place your finger over the camera lens. This means that the camera basically transmits the colour pink.
Except - and this is the clever bit - the shade of pink changes whenever your heart beats. And so it can tell (given a couple of seconds) what my pulse is. Genius!
(And free on Android, despite being $2 on iPhone. No idea why.)
