This reminds me of https://www.codeux.com/textual/

The software is on GitHub (https://github.com/Codeux-Software/Textual) and you can compile it yourself and, thus, remove the "you gotta pay" checks and such. If you can do that you are free to do that... or you can just pay for it and don't have to bother. It's not crazy expensive ($5.99), but I decided to go for the former just because it was more fun to me. If I had used his software for much longer and more often, I'd have eventually paid for it, I suppose.
