iOS: ZenAwake ditches sharp alarm sounds and brings you out of sleep in a more gentle way. Ten minutes before you are scheduled to wake up, the app sounds a gentle chime. That chime increases in frequency slowly over the next 10 minutes to bring you out of a deep sleep naturally.
You can see the idea behind ZenAwake in the video above. We are not totally sold on whether there is real science behind the whole "golden ratio" calculation behind the wake-up chime, but it can be nice to hear a gentle sound that slowly gives you time to rise out of a deep sleep. Once you do wake up, ZenAwake greets you with an inspirational quote or passage to get your day off on the right foot.
ZenAwake is brand new and currently only available on iOS. The developers told me that they are interested in seeing how the iOS version does first and how much interest there is in an Android version. You can sign up at their site (link below) to be notified when the Android version is available. In the meantime, iOS users can grab the universal app for $1.99 in the iTunes App Store.
