The animated nursery rhymes are the best part of this app, which starts with a clever spinning menu. The free version of the app gives you a taste of each of the four activities; and one video. The rest of the content can be unlocked by purchasing a subscription for $30 per year. In the alphabet activity, you first listen to a song about a letter-related object (Apple for A) and then fill in a picture of the object. You can download the app for free to get 3 letters. The additional purchase will be applied to access all the letters of the English Alphabet.

There's no third-party advertising, and there's no need for an internet connection. But there's not much content given the price. Note that you can watch all Dave and Ava videos for free on YouTube, at http://www.youtube.com/daveandava, The app was made in Saudi Arabia.
