Sleep Cycle is an alarm clock designed to analyze sleep data and wake you up as well rested as possible.

Now more than ever people are going to bed later and waking up earlier resulting in poor sleeping habits and a serious effect on one's health. According to a recent study, it has actually gotten to the point where 43.7% of the US population between the ages of 18-25 years old reported themselves as “unintentionally falling asleep during the day at least once in the past month”. To help improve your quality of sleep and ability to stay awake during the day an iOS application called Sleep Cycle has been developed and put on the market for an affordable price.

Sleep Cycle is intelligently designed to monitor and analyze your sleeping patterns with the mission to wake you up via an alarm at the moment that will make you feel the most well rested. This means it will not wake you during a deep sleep, but instead it will wait until you are in a lighter sleep stage before it decides to trigger the alarm. You still will not oversleep, as you set the interval in which the app will be allowed to wake you up. For me personally, I set it up for a 30 minute interval every morning that will wake me up in between 8:30-9am depending on when I am going to be the most well rested.

The interface is fairly simple and visually appealing, but I would like to see some more data taken for each night. For example, you can see the graph of how you slept the night before ranging from “awake” to “deep sleep” except there is no real estimate of time you were asleep. Instead, you only get to see the time you were in bed which isn't all that useful. However you do get a sleep quality percentage statistic that must run off some special algorithm that calculates how well your night's sleep actually was. A “white noise” feature is also available in the settings allowing you to set a constant noise to fall asleep if you are someone who has trouble sleeping in a room that is too quiet.

Some other small complaints deal with the choice of alarm sounds and the volume in which they are played. There have been several times where I have woken up and the alarm was going off for a couple of minutes before it was enough to wake me up. This is a pretty scary thing if your a heavy sleeper since that last thing you want is to oversleep and be late for work or whatever other place you need to be. For light sleepers, I don't think you will have a problem.

So far with using this app I have used it for 14 nights and I have noticed a slight increase in my energy level throughout the day. I wouldn't say it's a drastic change, but one significant enough to warrant the $0.99 price tag this app is retailing for. I think some of the reason why it has not helped more is the fact that I am sleeping with a dog in my bed. Since the app works using the iPhone accelerometer, the output of my sleep is likely getting skewed each time my dog moves on the bed throughout the night. Therefore I could be in a deep sleep for 3 hours straight, but if my dog were to switch positions during that time it would not show that way in the results. This also goes for couples who sleep in the same bed. I don't really see anyway around this so it is a pretty significant issue if you are not sleeping alone.

Overall, the app is well designed and has an appealing interface. There are some small changes I would like to see, but it is ideal for a light sleeper who sleeps alone at night. If you are a heavy sleeper I do not think it is a bad idea to spend the $0.99 and give it a shot. Unfortunately, if you sleep with a pet or significant other at night you will likely not get accurate results and for that reason it might not be the best way to spend a buck.
