Build a mobile app to save info about books I read already. Scanning bar code in the book should save it in my "read" library. Useful for folks who go to library & not sure whether they read a book or not. For eg. picture books of my kids. Also creating multiple profiles is another bonus feature. So I can store books by name of the kid
