This is a very simple app that was designed for children. It simply displays the letters of the alphabet, and an animal that begins with the corresponding letter. When the letter is tapped, its name is said.
This app locks the home and back buttons so that the child can not exit and play with things they should not. It also provides the option to automatically enable airplane mode.
You are given the option to display upper case letters or lower case letters, and to enable vibration when the letter's name is said.
To move between letters, simply swipe left or right. To exit the app, you select the "exit" menu option, then long press the "stop" button that will appear. A short press on the "stop" button will make it simply disappear.
This app will not work on Android versions newer than 3.2 (Honeycomb) due to the method used to lock down the home and back buttons.
