The easiest way for our non-verbal son to communicate "yes"/"no" choices to us.
Works on iPhones and iPads but he often wants the device instead of the choices he is shown so this version of Yes No Helper includes Apple Watch functionality so he can make the choice on the watch. Until the watch plays video, we dont have to worry about him wanting to take our Watch :)
Yes No Helper uses "yes" and "no" choice images that he is used to because the goal here is allowing him to communicate with use as easily as possible.
