The device's mainstay, however, is its low-power radio frequency emitter that sits behind the clock's interface. With a maximum range of about 5 feet, it tracks your motion and breathing patterns while you sleep. Gear4 execs reassured me that the levels of radio waves emitted from the SleepClock are less than what you get from a Bluetooth-activated phone or a Wi-Fi router. To get the clearest readings, it has to be placed nearby, facing your body as you sleep, without any obstructions in between.
Once you wake up, you can turn off the motion sensor and all your sleep data will be logged into the app in an easy-to-read layout. You can see how many hours you slept, how many hours of deep sleep you got (by monitoring your breathing movements, SleepClock can tell when you're in a state of deep, REM sleep), how long it took you to fall asleep, and how many interruptions you had while asleep.
Weekly, monthly, and yearly summaries give an even broader view. These stats allow users to see if they have a consistent sleep routine, how they compare with the average person of the same age and sex, and whether they're reaching their ideal sleep target. You can also share all this information to your Facebook and Twitter accounts, though I can't really imagine why anybody would want to do that.
On the whole, the Renew SleepClock was easy to use and setting up the alarm and motion sensor was a breeze. The user experience, however, is a little harder to gauge when it's 7 in the morning and all I do is grunt and try to find the snooze button. Though I couldn't tell how well it measured such small movements like breathing, it was accurate when I moved around a lot. Waving my hands several times near the clock, for example, would immediately register on the app.
The device's sound quality was also ample. Though it's not designed to deliver the best audio quality on the market, the music sounded crisp and rich. With a strong signal, the radio was clear and increasing the volume to its maximum filled my whole bedroom with music. Despite not having much bass, sounds came off full-bodied, with no extraneous buzzing or tinniness.
I especially enjoyed being woken up through a gradual increase in music volume. The default sounds that are included in the app offer a wide variety of calming noises to start off your day (though waking up to the "rainy morning" sound was a little confusing since it contrasted with the sunlight that poured in from my window). At first, I was worried these sounds were too peaceful to be able to wake me up, but they never failed. And because of the 20-minute window I set up, I was pleased whenever I woke up a few minutes before I absolutely had to.
All the data was interesting and easy to read. Graphs and stats were presented in a clean and attractive matter, and it didn't take much time to conclude that compared with the average twenty-something woman, I wasn't getting enough sleep. Written summaries were also clear-cut (if not a little reprimanding) and included things like: "You go to bed too late to get enough sleep."
I do have some complaints, however. You can't set up exact times for your alarms in the app, for instance, only times with intervals of five minutes. True, rarely do I need to wake up at 5:53 a.m., but one never knows. Also, for all its customizable options, you can't adjust the snooze time, which is set to 5 minutes.
After spending several weeks with the Renew SleepClock, I did become more aware of how little sleep I was getting, but it didn't drive me enough to start changing my habits drastically. And while I did enjoy being woken up more peacefully, I couldn't say that I felt less tired or groggy. Sure it's more pleasant waking up to an Australian rainforest than a jarring bell, but it made no real affect on how tired I felt in the morning. If I did somehow start off the day more refreshed and energetic, it certainly wasn't noticeable.
Whether this device is right for you depends on your priorities. If you're determined to gather information about your sleeping hours, or are extremely curious about your nightly habits, the SleepClock will help you with that. It'll also provide several alarm clock features and the sound quality is good to boot. But if all you want is a simple alarm dock with a fantastic sound system, perhaps it's best to look elsewhere.
