Another app shout out today for Lil Sub app for the iPad (normally $1.99). This very cute little app simulates a submarine exploring the underwater world. You come across all sorts of interesting sea creatures in your exploration. The app is designed to engage babies and toddlers in cause and effect play with cute graphics and a variety of songs. Normally a paid app, this is available for a limited time for free download.
Recommended for babies and toddlers.
Update: Lil Sub has been updated since I posted this review. They have introduced a lot more interactivity and control over the objects you explore with more sounds and effects. Also, there are a lot more objects to discover. They have also added a learn to spell feature which introduces words and ocean themed objects. You pop the letters of the words of the objects that appear to hear the word spelled.
