Baby Countdown app updated today in Google Play. The images below have been inserted as additional background choices inside this Facebook shareable app. These invitation images can be used to invite facebook friends to baby shower; app works as straight up countdown to baby birth, announcement of baby birth or invitation to baby shower. Also available in iTunes. (Today's updates have not yet made it to iTunes).
This is what it looks like on my S4.
