The 'SmartNap' timer app looks to make users more efficient when it comes to taking a nap when they're feeling fatigue. Instead of requiring users to wear sensors or other devices in order to track their rest, the 'SmartNap' app works with just your smartphone.
To use the 'SmartNap' app, users simply climb into bed or lay down in a comfortable area that's suitable for rest. The app will prompt them every two minutes to tap the screen; when the user does not respond, it's assumed they are asleep and the counter commences. Users will be awoken by an alarm in the timer app after roughly 26 to 28-minutes of rest, which is purported to be the ideal time for a nap.
