About

Reading App Builder helps you build customized apps for smartphones and tablets. You can use it to make apps containing picture books, health and community development materials, song books, illustrated stories and libraries of easy-to-read books for new readers – each with the option of synchronizing text and audio, highlighting each phrase as it is read. The app menus, icon, splash screen and colors can all be customized for your language and culture. To build an app, you specify the text and audio files, the app name, the fonts, the colors, the about box information and the icons. Reading App Builder will package everything together and compile the customized app for you. You can then install it on your mobile device, send it to others by Bluetooth, share it on microSD memory cards and publish it to app stores on the Internet.
