I work as an SLP in a school for severely handicapped children, the majority of whom need some alternate form of communication. Most of our staff havent had sign language training, so it was hard to ask them to support my sign language lessons with the kids because they couldnt remember the signs sufficiently. Also depending on the activities of the day sometimes a particular word would become relevant during a teachable moment. I had my school put the app on the classroom IPads to help the staff gain easy access to signs at the very time that a certain vocabulary word becomes relevant to a child.
