Twin apps

I've only found one really good weekly pregnancy app, Baby Pics. I do enjoy it. It has a ton of cute artwork for pictures. The filters kind of suck but I generally use another app for that and then use the Baby Pic app to add the words. However, I just hate that I can't make it say "Babies are the size of" instead of "Baby is the size of" and there isn't a lot of twin related artwork to add to the picture. Does anyone know of another app that is more centered toward pregnancy of multiples? I'm 33 weeks so it is kind of late in the game to start now but I would probably just go back and redo the pictures that I did in the baby pic app.
