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.
Probably, the reason they disappear is that this is the sort of "finished software" that Google makes it very infuriating to keep on the store. On Android you can build an APK like this and it will literally work unmodified for a decade. Google can't stand that and makes you make changes to keep up with shifting policies.
Those interesting things won't pump up the perceived value of Musk companies to stratospheric levels - or dare I say - to the moon. He needs the public to believe that to earn the trillion-dollar package from the Tesla-Twitter-SpaceX conglomerate, even if the latter turns out to be the only profitable arm of the conglomerate.
