The key to a higher quality life is through self assessment. To improve performance, break habits and adjust personal behavior, one must quantify his or her life with gadgets, apps and spreadsheets that help track personal trends and identify areas for improvement. I am very much on board with the Quantified Self school of thought. I maintain spreadsheets galore.

I have never been able to track my sleep in spreadsheets. Why? Well, because I am asleep.

Enter Sleep Cycle Alarm Clock. My friends Drew and Nicole introduced me to this rather handy iOS application that graphs your sleep phases. Place your iPod or iPhone on the bed next to you at night and the accelerometer will monitor your every move to determine which phase of sleep you are in. The main purpose behind the app is to wake you during your lightest sleep phase where you feel rested and relaxed (in a specified time range rather than a hard alarm time), but I have found it more useful for the sleep graphs.

Above, my graph from Friday – went to bed at 1:40am, woke up at 9:59am and slept a total of 8 hours and 19 minutes (believe it or not, college friends – I actually sleep now!).

With only a week of data, I can already see trends. I am taking notes on pre-sleep activity, successful bed times, successful waking times and more. Apparently, a glass of wine within an hour of bedtime has helped me to sleep quicker. Uh oh!

Keep track and you can unlock self improvement.
