Not surprised interviewers aren’t very interested in looking at an app with you. Having produced some code that runs is the lowest possible bar to cross, and if your resume said ‘I wrote this app’, they are probably willing to give you the benefit of the doubt and believe that yes, indeed, you got an SDK to emit an executable that actually ran. Seeing the app isn’t going to give much more information.
