After looking for a physical book inventory app for quite some time, paying for some duds along the way (some of them highly praised and priced, but stuck in the past in terms of looks and functionality), found Book Track and was immediately hooked. At last an app for this task with a modern look, with iCloud syncing with its iOS and iPadOS siblings, smart drag and drop functions, barcode and cover scanning integrated... Finally can start my catalog with minimal pain (400 books already logged, many more to go). On top, Simone, its author, is reachable and responsive for support and feature requests. With some room for improvement on a couple non-critical rough edges, Book Track is my choice and I'm proud to support and recommend it.
