The quality overall on iOS is way better than Android. There are obviously going to be a few outliers but I’ve worked at multiple companies where Android is an afterthought (in every way imaginable). I’ve also heard the same from peers in the industry.

iOS apps bring in more money and that absolutely shows in the time and effort companies put into their apps. The big names (FAANG) might have equality but once you leave the top apps the quality difference can be stark.
