There's also Boop, which is open source: https://github.com/IvanMathy/Boop

I’d recommend [Boop](https://apps.apple.com/us/app/boop/id1518425043?mt=12). It’s free and open source.

This is incredible! Definitely worth the price for me. Thank you for mentioning it!

Oh, wow. I was excited for this but the website sure doesn’t make it obvious that most features are locked behind a paywall.

(Sure, I see the very small pricing link in the header nav now.)
