Ever wonder how many hours of good zzzzz's you're really getting a night? Now there's a way to track that information, with the non-invasive Renew SleepClock, which uses a combination of an iPhone app and wireless device. While it may be one more thing to put on your nightstand, the Renew SleepClock doesn't require the use of any extra equipment like wrist watches or headbands. The sensor in the device tracks your breathing rate and movement, measuring how long you spend in deep, light or even no sleep. It sends the info to the app, which displays it on the iPhone screen. You use the app to keep a record of your sleep patterns; what you do with the information is up to you, of course, but if you're a Tylenol PM taker or familiar with Ambien, you may find this kind of record-keeping really useful. And, it includes a speaker with FM radio that you can use (as well as your own music) to help you go to sleep; once you are, the audio automatically fades (it's part of the device's "auto sleep detection"). You can also customize alarm wake-up options from your iPod music, the radio or "gentle wake-up sounds" from Renew SleepClock, which also works with the iPad, as well as the third- and fourth-generation iPod Touch.
