This is a simple viewer for PassBook® files.

The app searches the file system, starting in the home directory, for passes,
and shows them in a list. A tap on the pass shows the details including the
barcode (usually the most important thing). The design is simplified compared
to the original app, but should be readable.

Passes close to the relevant time are highlighted. It's also possible to
highlight passes close to relevant coordinates (check settings). The top
highlighted pass is shown on the cover, with the cover action opening the pass
