I use this one:
play.google.com/store/apps/details?id=de.orrs.del…

It can usually get the status of most courriers unless they’re actively hostile against API/scraping.
Worst case you can still track status manually, or open the webpage.
It doesn’t track payment, but I don’t usually have a tracking number before paying.
I think you could technically add your own custom status entry.
I keep them as active until shipped and verified after which I mark them as completed.

Works well enough for my needs.
