The real reason I developed the app was to automate birthday wishes. I don't visit Facebook very often, so I wanted a way to automate birthday wishes. The automation is very customizable. You can configure a time range for it to post. The app will randomly pick a time within the range. It comes with 10 "canned" birthday wishes. You can edit these "canned" wishes or add your own. You can select the ones you want and it will pick from them randomly. You can specify custom wishes for your close friends. Plus it is easy to exclude or include which friends you want to send automated messages.
Of course, not all friends put their birthday info on Facebook and some have their permissions set so that 3rd party apps can't access the birthday information. For these cases I've added manual entry so you can use Best Wishes for all your friends.
Check it out and let me know what you guys think. I'm open to feedback and feature suggestions. The full version costs $0.99. The Lite version is free.
MOD EDIT: FREE VERSION CAN BE FOUND HERE
The main difference between the lite and full version is the level of customization that you can perform. The full version allows you to enter custom birthday wishes, include/exclude friends, and it has ten pre-defined birthday wishes that are editable. The lite version only has one birthday wish ("Happy Birthday!"). The rest of the functionality is the same.
