About this app
Call Number Shelf Trainer is an offline tool designed for library shelving practice, library and information science study, and staff training. Practice Chinese Library Classification recognition, call number breakdowns, same-class book ordering, and shelf position judgment. It is useful for pre-employment self-study, pre-shift review, daily training, and exam preparation. The app requires no login, does not connect to the internet, and does not collect personal data. Practice progress, mistakes, and statistics stay locally on your device. Compared with notes or spreadsheets, it offers sorting drills closer to real library shelving work, mistake review, and quick rule lookup, helping learners train with clear goals in a focused professional tool.
