Recently I cleaned completely my home screen (iPhone). In the dock I keep Phone, a folder with Safari and Mail, a folder with what I used to have in my home screen (Calendar, todo, clock... 7-8 things) and the "social" apps folder (Facebook, Whatsapp, iMessage, etc). The rest, I have it in a secondary screen, neatly ordered by folder. And anyway, when I need to open almost anything that is not in the dock, I just search for it, just like I do on my computer. It's like having an uncluttered desktop so I can see the background.
