For young listeners who love vehicles, this app is a great companion for the books of the same name. It features bold colors and simple navigation with a bright orange triangle at the bottom right for page turns. Sentences appear in black and are highlighted as read aloud (you can turn this option off, too). Pressing on a word will pronounce and display the word again. Sound effects are minimal: Pressing on objects in the scene results in identification of the object, and sometimes prompts additional sound effects. I like the non-distracting format of this app, ideal for younger children. Pressing the orange arrow at bottom center gives the option to close, go to home, navigate to particular pages, record your voice for read-aloud option and turn on/off sound effects.
We also used the activity app, Peekaboo Barn by Night & Day Studios ($1.99 on App Store and Google Play)
A wonderfully simple and pleasing app: a red barn is front and center, and tapping on the wiggling doors opens them to reveal a farm animal. The animal noise is heard, and the word for the animal appears. Tapping again closes the barn doors, and the child can tap to open the doors and reveal another animal.
This one is great for interaction, animal identification and sounds. Additionally, there are many language options, making this a good one for non-native English speakers or for those wanting their children to learn animal words in another language.
