Oh! You're talking about [flag semaphore], right? It's not really a language, since the signals are meant to represent letters of the Latin alphabet or Japanese syllabary, not words. I'm not sure how useful it would be for you, though. You would have to signal every letter of every word you were trying to communicate. In addition, you'd have to use both hands to signal the letters, you'd have to make sure your phone was positioned somewhere just right to capture your movements. You'd probably be faster typing with the one hand you've got! ٩(◕‿◕｡)۶
