After trying some of your watchfaces, I must say I like the "contemporary digital rings" best.
It's a bit like a much more cheerful version of my arc.

Also, I like "worte" a lot. But maybe consider changing the second "true", because it shows as "fünf nach drei uhr" instead of "fünf nach drei".

Another thing I noticed: I think it would be better if you tried to put the various get-screenshot.sh outside of the project directory and remove it from the repository. While useful, it does not really belong there IMHO. Perhaps some of it would be nice to have in the README.md…?

Regardless of my bickering: Great job!

Oh, and "my" battery reading "code" is hardly anything, just some imports and two QML elements directly taken from the asteroid launcher itself. Feel free to take anything you need.

cheers!

edit: fixed a thing on arc I missed yesterday where Qt Creator sometimes inserts 0 at font sizes and made it less noisy at start up (journalctl).
