I went to the AlDente sight but couldn't find a version for Catalina. Plus I read the comments and there were several complaints, including by you! I think I will pass. 
Yeah, it's only available for Big Sur and later (programming language issues), and it's nowhere near a finished product under any circumstances.
I had a problem with it a while back, and I trashed the latest update, because it kept asking me to jump through hoops for no apparent reason. In addition, there's no way to report problems unless you've purchased the paid version.
I have learned how to work with it, though, and it keeps my battery at 50% without requiring any attention.
(Hmmm... I just looked at the FAQs on the AlDente website, and on the one hand, it looks like my problem could have been avoided had I looked sooner, but on the other hand, I had no reason to think I needed to look before I ran into my problem. Catch-22!)
