The Scheduled option is where you'll go to see your Scheduled Facebook birthday greetings that you have opted to send. EasilyDo will not automatically schedule birthday wishes for you, so you'll have to turn the Birthdays option on from the Features page (tap the gear icon to get there). Once you have your friends' birthdays shown to you in your feed, select the 'Schedule' option at the bottom of the screen once you've picked your personalized greeting and image. Head back to the Scheduled section in the Account page and you'll see your birthday greeting there.
Once the scheduled birthday wish is delivered, you'll see that card in the History section of the app along with all the other tasks you've completed with EasilyDo.
