Toddler’s Seek and Find has a number of interactive picture book app for the iPad and iPhone that are top rated, award winning, and very popular. Currently, Wonderkind is offering the HD version of Animal Circus for free download for a limited time. This is normally $1.99. I also linked the free version of My Little Town app.
This app is full of colorful hand-drawn illustrations, and nearly everything on the page is interactive with interesting and funny animations and sounds. This makes it a perfect app for toddlers who are just interested in tapping the display and aren’t ready for more complicated play on a device. M still loves this app, and it always elicits a ton of giggling. Even though, I have clourophobia, this app is cute enough that I can handle playing with it with M.
Highly recommended for 18 months to 4. Grab the HD version of My Animal Circus while it is still free. Check on the developer’s page for other versions of the apps that will work with your device.
