I am constantly in development, but here is a sneak peek at the current app I'm developing.
It's called: Every Man's Baby Countdown. You've seen the baby countdowns for soon-to-be mothers, well this is for the soon-to-be father. Based on how far along the female is will show you how big the child currently, except I'm not comparing it to lettuce and a peach pit. (see below for a few screen shots)
