Lark's silent alarm wakes you, not your bunkmate

Alarm clocks are so primitive. At the appointed time, your device shrieks to life, rudely startling you awake--along with whoever is next to you.

Entrepreneur Julia Hu wants to bring modern sleep science into your bedroom with Lark, a vibrating, silent alarm buzzer you wear on your wrist. The device doesn't just buzz at the appropriate hour, though. It also beams data over Bluetooth to an iPhone app about how well you're sleeping, based on how much your arm moves. An Android version is coming soon.

The device will be sold in Apple stores starting June 14, and its available now on Lark's Web site for $129, plus an additional $60 to get the feature that shows you a seven-day personal sleep assessment based on the data the wristband collects. The sleep analysis is based on algorithms developed with the help of Harvard University sleep expert Dr. Jo Solet and professional sleep coach Cheri Mah.

"Sleep is the under-appreciated third pillar of health next to a healthy diet and regular exercise," Hu said.

In my own trial of the "Silent Un-alarm Clock" a few nights ago, Lark told me I got 6 hours and 28 minutes of sleep. It also said that it took me 32 minutes to go to sleep and that I woke up 5 times--none of which I remember. Yet apparently this level of nighttime activity is pretty good. It was worth an 8.9 out of 10 on the Lark scale of sleep efficiency. … Read more

Atomic clock tool

Chronos Atomic Clock Synchronizer is a small utility that synchronizes your Windows system's internal clock with online time servers that use ultra-accurate atomic clocks. Yes, Windows already does that; Chronos adds flexibility and displays more information, such as latency and correction in fractions of a second. Best of all, you can specify a connecting interval instead of relying on Windows' unspecified "scheduled basis." By querying multiple clocks simultaneously, it returns the most accurate average of the current time.

Chronos has a small but attractively colored interface with a list of Time Servers as well as their latency … Read more

Personalized clock screensaver

Style-7's Photo Clock-7 is a free analog clock screensaver for Windows that lets you use your own images as a clock face background. It has the usual analog clock options, such as removing the second hand, and editing things like font color, but the ability to use your own picture for the background makes it a more interesting choice, in our opinion, than other screensavers of the same type.

We installed Photo Clock-7, opened our screensaver properties, selected the program, and clicked Settings. A small dialog let us choose background and font colors, including custom colors via a standard … Read more

iQ Alarm Clock annoys you awake

It's like waking up beside a Geeks Who Drink champion. Designer Oliver Sha obviously has a hard time crawling out of bed in the morning. He solved the problem by creating the iQ Alarm Clock, a smarter-than-thou invention that won't shut up until you solve a series of quiz questions. Forget about a snooze button. This device demands mental awareness.

Questions may involve figuring out which object doesn't belong in a group of illustrations or what comes next in a numerical series. Thankfully, there's a hint button to keep you from throttling the alarm into submission.

Sleep lovers may try to reach for the battery compartment, but Sha has already thought of that workaround. The battery cover is tamper resistant to keep prying fingers at bay. The only way out is to get your questions right or hold down the power button for 30 seconds. The prospect of having an Alex Trebek experience every morning may not sound too appealing, but it will get the job done. You'll be up and at it and maybe feeling a little smug for having conquered your clock in a battle of the brains. … Read more

The big time

Big Free Clock is exactly what its name suggests: a free utility that displays the time in a large format. Although it's a fairly basic utility, it comes with enough options for customization to make it interesting.

The program's interface is plain, just a large digital clock with two buttons: one to minimize it, and one to display the options menu. There are quite a few options, too; users can make the background and numbers transparent, change the number color, switch to 24-hour format, and increase and decrease the size of the numbers. Our first impression of Big … Read more

Just in time

For the most part, computers do a pretty good job of keeping accurate time, but every now and then they need some help. AnalogX Atomic TimeSync is a simple utility that lets users sync their system time with time information retrieved from the Institute for Telecommunication Sciences, a government agency that's part of the U.S. Department of Commerce. Although it's a fairly basic program, some of its features are more intuitive than others.

The program's interface is plain, with boxes displaying the local time on your computer, the network time retrieved from the server, and the … Read more

No cause for alarm

Alarm clocks are a standard feature on most cell phones, but computer clocks typically don't do much but display the time. Free Alarm Clock adds alarm functionality to your computer, letting you create multiple alerts that can wake you up or remind you when it's time to do something.
