PowerNap is a very powerful, yet intuitive Nap Timer application that focuses on ease-of-use and powerful functionality. Setting a nap duration is as easy as moving a slider. Once the alarm has been set, PowerNap will display an interactive dashboard notification to allow you to view the remaining minutes of the nap, add or subtract additional minutes to the duration, and even cancel the alarm. PowerNap is also very customizable. You can choose your own alarm ringtone, default nap duration, vibration settings, and even your default snooze duration. The vibration feature even includes a randomizing algorithm that prevents the user from "getting used" to the vibration pattern and not waking up. If you're an avid nap taker, this is one powerful and easy-to-use tool you'll want on your webOS device.
