Can an App Deliver Beauty Sleep?

Ever wake up to your alarm feeling like you haven’t slept at all? Experts say that adults should receive 7-8+ hours of sleep per night. With my busy schedule I don’t always receive the recommended amount. Routines, lifestyle and age are predicted to affect our sleeping patterns. I’m a bit of a nerd and have always been intrigued with sleep and dreaming. Imagine my surprise when I ran across an inexpensive sleep tracking device while reading one of my favorite blogs.
The entire blog post that day was about the Sleep Cycle App. It tracks what state of sleep you’re in, average time spent asleep, how long you were in bed, etc. After using the app for 5 nights it will calibrate your sleep and rate it. It also allows you to enter sleep notes such as: Ate Late, Stressful Day, Worked Out, Drank Coffee. You can even make your own sleep notes! I can’t be sure how accurate the information is but it’s definitely interesting to review each morning. I’ve been using the app for almost two weeks and have no complaints.
The app is very user-friendly. You simply put it on the corner of your bed face down each night and turn on the app. You don’t have to attach anything to your body and the app is only $0.99. With the phone being close to my head I typically turn my phone on airplane mode. Forget about annoying alarm sounds. The app offers a myriad of “soothing” alarms that will wake you when you are in your lightest point of sleep. It also lets you choose a 30 minute time window to wake up.
I’ve posted some pictures below of the graphs it populates to give you an idea of everything it tracks. The dates are listed at the bottom of the graphs.
Would you ever buy this app? What are your thoughts on it?
