>Millions of people are worried that they can not get enough sleep.
The amount is too large to ignore pebuat gadget. As a result, more and more devices are intended to track, train and improve the performance of sleep, take advantage of the computing power of mobile phones and personal computers.
I’ve tried three of them: Sleep Zeo Mobile Manager and the Lark, both of which cost $ 99; and Elite SleepTracker $ 149. All sensors use you wear to bed to measure how long and how well you sleep. They also feature a silent alarm that wakes you by vibrating, so you will not disturb others.
The most complicated is Zeo, which measures brain waves and eye-muscle movements to calculate how much time you spend in the cycle of sleep and rapid-eye light, as well as how often and for how long you awake at night. Data is transmitted wirelessly to a free Zeo app on the iPhone or Android phone.
You wear the Zeo more middle of the forehead, held by an elastic headband.
On the other hand, Zeo with a simple application automatically synchronize my data, give me the information that impressive, “score a single bed can I monitor to keep track of my improvement. Even more analysis is available on the website Zeo, including training regimen to help me increase the value of I.
Lark sensor is much more convenient. As Zeo, no rubber bands, but you wear this one around your wrist, where it monitors your sleep to track your movements on the night.
The data is not as detailed as Lark’s Zeo. It captures how many times I wake up at night and for how long, but not out of the amount of time I spent in different phases of sleep.
The two devices differ in how they wake you up in the morning. The Zeo to find a point about your designated alarm time of the sleep cycle when it senses that you are most likely to feel fresh. Lark The transfer of data to the iPhone and begin to vibrate at whatever time you set. The company said it concluded that users do not like to wake up earlier than they need.
The Lark, which also offers a sleep-training “pro” service for an additional $ 60, currently works only with Apple IOS devices. An Android application is in the works.
SleepTracker Elite is a bit of a hassle to use. Unlike the others, does not require constant charging. It’s also the only one you might dare to wear in public: a watch, a little waterproof digital greatness.
Balanced against their advantages is that it works only with computers. You must download and install software for Mac or Windows PC. Also not wireless, you transfer the data from hours to a computer via the included USB cable that clamps to the contact on the back of the watch.
SleepTracker programming requires a lot of button pushing and navigating the various digital-watch the screen. Once I get up and running, it’s a good job of waking me and catch my data, even though I had a bug in the Windows software which first prevented me from seeing my results, I concluded to sleep 17 hours.
