Extreme minimalism

The app works but I can’t seem to get the Lock Screen widget to show the LST. It shows a time when selecting the widget as a preview, but not on the active Lock Screen widget itself. I’ve tried all the privacy/notification settings I could find, updated iOS and reinstalled. The app doesn’t show up in some lists where other app settings would appear.

Small bugs but unique in function

There seems to be a bug in how the Watch app enumerates complications, and took a few restarts and resets before I could get everything just right, but this app is unique in that you can get sidereal time with just your longitude and display it on the watch face.

Essential

Essential app for amateur astronomers. It is simple and to the point. Thank you so much.
