Which looks better? This article in Business Insider says these 11 screen shots prove that “Android apps are uglier Than iOS apps.” I looked at them and I just don't see it. The Android apps don't look worse to me and I generally don't see what the captions of the various images assert.
I do see that the iOS apps look more consistent in some ways.
To me, many of the Android apps look cleaner. In one example the iOS app has a search box at top (taking up a lot of space) but I know Android has a search button that works in all apps (that I've experienced and that have search), so you don't need a search box always on screen.
In another case, the iOS app has letter-of-alphabet dividers for a list but I know on Android if you grab such a list and scroll a little tab appears. That tab has the current letter of the alphabet and you can quickly move it to the letter you're interested in, the list will scroll quickly as you move through the alphabet.
