Extra meal swipes and dining dollars

I'm a freshman at Tech currently on the flex meal plan. I know for a fact that by the end of the semester, I'll have remaining dining dollars and meal swipes. I heard about the app that some UCLA kids developed for unused meal swipes. I was wondering if we had anything like that and if we don't:

1. is there like a fb group or smth for unused meal swipes
2. shld i build smth like that (ik it got shut but it would be a really cool learning process and project for my resume lol)
