Does get slightly hot to be honest, not terrible though. I guess it depends on the size of your bed. I just slip mine to the side of my pillow, so it doesn’t get covered. Love the app! Written about it on my blog – http://www.kevcharlton.com/sleep-cycle-iphone-app

I'm not sure how this might work for you, hugo. One of the settings is to "calibrate" so the iPhone gets the sense of the surface on which you're sleeping. If you are on many different beds, I wonder how that might impact its performance. I've slept on many hotel beds with this as my primary alarm – and have never used the calibration feature – but I always return home to the same mattress. Additionally, how do you find a place to put it if you're sleeping upright in an airport lounge?! 😉

In America, our saying if someone is grumpy is "you must have gotten up on the wrong side of the bed…" – which makes it sound as if we're more promiscuous than the Dutch! HA!

Figge: How exciting to hear your results are similar to mine and those who rated it at the App Store! Enjoy!

You're welcome, Josh!

Sounds as if you should contact the dev's. They are nice and I'm sure they will respond. Either something is amiss with the program, OR you toss & turn like mad even when you're in a deep sleep… that or gremlins are jumping on your bed when you're sleeping! 😉

In any event, let us know the outcome.

Thanks for the response 🙂

I'm going to stick at it (at the very least it's an alarm clock). I'm currently at home (student) so i've got my single bed. I don't know if switching to a double (at my uni house) will make any difference. The main problem is that it's not showing i sleep at all, it's almost as if it's too sensitive. Even when i'm in deep sleep (as the line dips slightly) the trace is still in the awake section and there's none of the large ups and downs like in yours.

I'm going to shoot an email to the devs, see if they can give me some advice! But good to know they're your traces so there's some hope.

Excellent info… thanks.

Now, if prescription medicine gets into the studies, there will be many years of ongoing studies to come. 😉

Graham:

How exciting for you that you also are finding it enjoyable and intriguing! I agree, it's a worthwhile purchase!! I wonder what the graphs look like when you awaken and have an "alert" day… is it just as low in deep sleep? My experience is that when my graph is in deep sleep, there was a reason (*hiccup*!).

Thanks also for pointing out that if you're sleeping with someone that your own body should dampen registering it on the graph! My wife is restless too – whether it's due to a cough, a restroom break, or a 2-year old – and I've seen little impact on the graphs (and my sleep…?!)

i have it on the edge of the bed, and according to the developers if you have a spouse your body should be enough to lessen the impact of their sleep patterns, i think it does b/c my wife tosses and turns like nuts lol

Those sample screen shots are real data from my own sleep chart. Although I don't have a parabolic graph (apparently I move frequently through the night – verified by hotel overnights), I never noticed that the calibration made much difference. If you sleep alone and are a deep sleeper, that might explain your graph; if you're in your 40's and sleep with a spouse, awakening more often seems normal to me! 🙂

At the moment it's just like a parabola with a flattened bottom ( _____/ sort of shape). So while it seems to register that i'm moving less during the night, it doesn't look anything like the sample screenshots and the graph never dips into deep sleep or anything like that.

But hey, i reasoned that 60p is worth the punt so i'll report back if it improves!

Actually the jury just came in on this one:

Really big really long term study showed no negative effects from the cell phones. Nokia would state that just as a CYA

I suppose there's an app for that… perhaps in the psychic area of App store? 🙂

There's a calibration feature that should help discern the movements – and I would recommend keeping it on your side instead of between the two of you. Please offer your insights and thoughts after you try it!

When looking at the App Sore, I see 85 total comments and 24 for the current version (as of today, 12/17/09). hmm….?

It's down to 79c so I splashed out. Happy Christmas me. Not sure how it's going to tell if it's me or my wife who is ready to wake up but I thought even just to get the graphs of when one of us got up for the toilet might be quite amusing! Not sure how long this post will stay open for comments but I'll certainly post something if I can.
Must say I'm a little confused that the app claims great things about its sales but there are no ratings for any versions.. Bit suspicious but hey 79c

The app does suggest that if you're uncomfortable with having the phone "on" that close to put it in Airplane mode. In my home, however, the iPhone replaced my landline so that isn't an option for me. Not to mention, when traveling I need an "always on" cell phone in case of emergencies back home.

Depending on the size of your bed, it might not be directly beside your head (mine's a king size and I'm usually at least a foot away from it). You're right about turning off things, though. I use SBSettings launch Settings and turn off notifications (Boxcar) and silence New Mail notices.

If you decide to drop the $1, let us know what you think of it!

Actually, no the phone doesn't feel hot at all. When you place the phone face down, it enters into power-saving mode and the screen blacks out (like closing the refrigerator door). I initially shared your concern about rolling over on it, but surprisingly when I put it closer to the corner of the bed (I have a king size bed) it remains out of the way.

Given the additional guests that jump into your bed in the night, I agree with removing the temptation (play toy, chew toy, cord, etc).
