Since April I've been using the Sleep Cycle app as my primary alarm clock. Basically, the app uses the microphone to try and tell when you are not in REM (deep) sleep to sound the alarm clock. You get to set a 30mn window during which you would like to wake up, and it tries to wake you at the most pleasant time. About 50% of the time I wake up at the last minute of the time window and feel just as groggy as I normally do waking up. The other 50% of the time though I wake up during light sleep and feel much better! I've been recommending the app for the past few months.
At it's very worst, it's still better than the default alarm clock. Another thing I like, although probably not billed as a feature, is that when the alarm is active if you switch to another app it shows in the top bar. Which acts as a gentle reminder that I shouldn't be using my phone right before sleeping. I've been working towards not having any electronics in my bedroom at all, but frankly it's hard and I'm not there yet.
Another added benefit of using Sleep Cycle is that you can actually export your sleep quality data. Which includes: Start Time, End Time, Sleep Quality (a percentage metric they made up), Time in Bed, and Activity (number of steps the iPhone pedometer recorded that day).
A project I'm working on is tracking some key personal metrics over time, the first one I've talked about here is my happiness. Sleep is another fun one, this is my raw data from Sleep Cycle. I'll refresh the Google Sheet periodically with new data.
It's nice to see that my average (and median) sleep times are both about 7.5 hours. This is what I believe is healthy for me, and I intend to keep it up. Meaning I'll have about 16 waking hours a day. Best to not waste too much of that time merely keeping track of it :)Share on Twitter Share on Facebook
