The mobile version of Tappie Puzzles is currently free for download right now. There is an HD version that is $0.99, but I am frugal, so the iPhone version is good enough for me. There are free lite versions of both that are available in case you miss the free offer.
This is a pretty cute beginner puzzle app featuring animals in their habits around the world and some space themed ones as well. Easy for toddlers to learn to manage puzzle solving since the pieces do not require any orientation before dragging into place. This is great for developing matching skills in young child.
Recommended for ages 2 to 3.
