The Signs and Cues app has three dictionaries in one: ASL Sign Language, Cued Speech, and Fingerspelling. Some words have yellow tabs, which means the "more" tab can be clicked to get an explanation of the word.
Signs and Cues combines the words from SignCueQuest, The ASL Adventure Game with YouTube's "ASL Word of The Day" and "Cued Speech Word of The Day" videos in a handy dictionary.
