More on Sleep Cycle Alarm Clock
That was good timing! I posted my review yesterday and then found out that the 2.0 update dropped on the same day! The new version includes historical graphs of your sleep patterns. Here’s my data from last night:

Went to bed / woke up: 11:13 PM / 7:00 AM
Total time: 7h 46m

My sleep graph

This wasn’t a good night’s sleep. I was more aware of the iPhone than I’ve been the previous few nights, and every time I turned over I thought of how it was being recorded for the graph. Then as the sun started to come up, the damn cats went berzerk. I didn’t sleep very soundly for those few hours. I finally got back into deep sleep an hour before the alarm… which meant there was no optimum time to wake me and I got up at 7am feeling groggy and annoyed.

Okay, so the jury’s still out on whether this is all make-believe. I’m trying to find scientific research backing the ability of actigraphy to accurately detect sleep stages, and I haven’t got proof yet. I think I need to get the Snook to hook his iPhone up too so we can compare graphs in the morning. I’m really curious whether he’s affecting my phone’s data…

  1. Grandma Flea - the normal look

    I want one! Just another reason to have one. I NEED one … What a marvellous device – I, too, don’t sleep well – I MUST have an iPhone – shame I’ve just bought an iPod. Bugger!

  2. Actigraphy is definitely used here for testing of sleep disorders like sleep apnoea. Not using an iphone, of course!

  3. The last two nights, I’ve hit deep sleep JUST as my alarm went off as well. Either it’s self-sabotage, or there’s some sort of quirk in the software. Hopefully when the program is done calibrating, it’ll wake me before I have a chance to do it again.

    I wonder how/if it’ll change in the spring/summer with the sun…

  4. Yeah i tried it last night but had a acid gurgling about in my stomach causing grief. Probably not the best night to test it out 🙂

  5. Oh, Patrick, the sun is here in Sydney already… 🙂 And Grandma Flea, yours may be reltsed to your age. Lots of middle-aged women have broken sleep patterns for a few years.

  6. I downloaded the app after you mentioned it last week – it would appear that I’m an even worse sleeper than I thought. I got David to try it too, just to see, but he knocked the iphone out of the bed halfeway through the night!

  7. Can you update on your experience with the app to date? Thanks!

  8. I haven’t actually used it lately, I’ll admit. No real reason; just haven’t been bothered!

  9. I’ve been using it for the past week or so and my patterns are a bit disturbing. Deep deep sleep and no gradual slope upward towards the end of the night. My husband installed it last night and he had a perfect upward sloping graph just like they show in the graphs.

    Wonder if they have a website where we can all upload our sleep graphs and compare. That would be interesting.
