TVTime

TVTime reminds you when your favorite shows are about to air. Search for your favorite shows, add them to your show list and allow TVTime to automatically remind you when they air by adding them to your calendar.
After adding shows to your show list tap the calendar icon for the shows you want to track and all future episodes will automatically be added to your calendar.
For all shows you choose to add to your calendar TVTime will remind you to tune in 15 minutes before the show airs.

This app makes use of the TVRage and trakt API's.
