Biscuit is an absolute hit with my kiddos so the Valentine Story was a must have on my list. It's $2.99. It has all the same options as the other Biscuit Apps: Read to Self, Read To Me, Auto Play. It also has a coloring book, sticker collection, memory game and puzzles.
Valentine Memory App - free
It's your classic memory game.
Cooper's Big Bear Hug App - free An interactive online story with puzzles and games.
I have a few others as well that I have not yet checked out. I just simply searched Valentine's Day in the app store and chose apps that were free. Here is what my organized folder looks like:
Lots of time to get these organized before Valentine's Day. If you have any favorites, feel free to share.
