I often find it interesting what people have on their computers and how they lay out their desktop. As I use my iPad Pro as my main computing devie I live by the apps I have installed. Below is the latest screen grab of my current iPad screen. I only have 1 screen as I like to organise apps into folders. 



My main apps are:

Evernote for document scanning, note taking and article reading

OmniFocus which is my second brain

Calendar which helps me focus my time effectively  

YouTube is my main consumption tool
