I have a simpler problem - I want a yearly calendar app (for Android) that just shows the yearly calendar (for any year), nothing else (no events, no reminders, no anything).

Any app I find seems to disappear from the Play Store after a couple years.

Bonus: show the weeks vertically.

		I second cal! Also I find bsdmainutils’s calendar quite amazing in its simplicity

Package: ncal

    Source: bsdmainutils
    Maintainer: Debian Bsdmainutils Team 
    [...]
    Description-en: display a calendar and the date of Easter
    [...] This utility displays a
    simple calendar in a traditional or an alternative and more advanced layout,
    and the date of Easter.

And here is a Bash script that runs ncal to show weeks vertically.
