The free version works fully, with a 10-puzzle cap and a small "made with" line; a license key removes both. Lifetime means the key never expires, for as long as the app is offered. Makes interiors only (no covers). Tested with automated checks and in desktop Chrome; not yet checked in KDP's previewer or other browsers, so try the free version first.
