Term to summarize webpage and mobile app

I am currently making a UX design course, so I am sorry if my question is silly.

I am starting with my first projects and this question that I´ve been asking to myself for a while, is now stuck in my head. Is there a (single) term to summarize webpage and mobile app? I feel that for usability tests and surveys, it will be easier to get users straighter thoughts with one term.

I know I could say web/mobile app. But most users seem to relate ¨app¨ with mobile products only.
