From Craig Hemsing:
Podcast Listening as a Sleep Aid. If the worries of the day are keeping you awake at night, try listening to a podcast. Sometimes even a few minutes of careful listening to an interesting podcast can distract you enough to fall sound asleep.There is already a good selection of great iOS apps for managing and playing podcasts during the daytime but most are difficult to use at night, especially if you need glasses or don't want to miss any of the podcast that you were listening to.NightPod makes nighttime listening easier by providing: A dark background with convenient brightness control Big, high-contrast text for easier reading A large sleep button with single tap 'top-up' Smart navigation buttons to quickly find where you drifted off A screensaver with a large clock and elapsed time counterNightPod can help you sleep on those nights when nothing else seems to work.
