Simple Yes or No is an app for teaching and practicing consent and preferences. The model is simple, allowing for training on recognizing and indicating the symbols and then training on associating them with using yes and no in making choices. Human users have the ability to isolate either the "yes" or the "no" as an aid in the training stage.

This app was designed for use with parrots, but could be used with other intelligent animals. The app can be used in day-to-day indication of choices by keeping it easily accessed on a smart phone or tablet.
