MacPaw apps, at least CleanMyMac and Gemini 2 are very nicely done, and useful to boot. Softorinos app WALTR 2 is in the same vein, looks nice and very useful.

DaisyDisk is amazing as well. --- From what I've noticed, they seems to have some overlap and they often do cross promotions. I actually think their advertisement verge on spam sometimes, but I still love their apps. Something else I noticed is that all of these seem to be run by eastern European people. I am curious if there is some niche/stereotype to be found in making high quality apps from those countries.
