AdDA app for iPhone and iPad

AdDA is an app that helps you to learn lipreading in mexican spanish. It has sections where youll learn to articulate all mexican spanish phonemes. AdDA has short videos showing how to form those phonemes. If you have some auditive capabilities, those videos will also help you learn the sound for those phonemes.
AdDA in its free version, includes word catalogs for 3 different difficulty levels. Theres even one section where you can write words or phrases and visualize the phonemes and their graphs. Theres another section where you can practice lipreading, because it will show you a sequence of graphs using the words in the catalogs. In that section you will be able to measure your progress because AdDA registers how many times it has showed you a word and how many times you have had it correctly.
