Sleep App for iPhone

So a coworker mentioned he used this app many moons ago, and I came across another reference to its popularity late last year, so I thought I'd give it a go.

You leave it running, phone face-down near you on the bed, and it reacts to your movements.

Here is the graph from last night (the best night so far, according to the data):


Why would it give me a warning, but say I had a good sleep? It's happened before.

Here is a record of all my sleeps:


It's an addictive toy, but I am not convinced of the science behind it!

How does it know you are in deep sleep? Your breathing? I don't get it. sleep studies involve a crap load of things being glued to you. Hmmm.

Nope. Vibrations.

And that's where the inaccuracy comes in: these don't have the sensitivity to pick up small movements, just fairly large ones like rolling over.

I guess they can invent an attachment...but still. :)

Hm, yeah, it can't be very accurate, I imagine. How does someone use this app if they have pets or a partner who sleeps in the same bed? And, even if it is just you, your brain activity and breathing play a large part in good sleep. It does seem like one of those toys that would be tempting to play with, even if it's not accurate! Why is that? Brains are weird. *snort*

Vibrations are what it looks for, so...if your cats sleep on the phone that would be a problem!
