Thank you for porting the project. I was able to compile it successfully. :tada:
Some topics which we may consider:
I am not sure whether the README files are necessary to be put under version control?
I hope that in file time-tracker-pio/.vscode/extensions.json the entry for unwantedRecommendations does not make any trouble. As this extension may be necessary for code formatting (see #11).
I am not a fan of splitting source and header files into different directories. Especially as I tend to logically structure the code with directories.

I'll remove the READMEs and also put all header files into the source directory. I've checked that this still compiles with PIO.
