Human memory is miraculous, but temperamental and fickle sometimes, at least in my experience, and I use all the help I can get to remember things. I'm all too familiar with the frustration of missing something or messing something up because you don't have a piece of information that you should have, and the relief when your past self did the right thing and recorded whatever you later needed to revisit (many times thanks to this app).
Now, I'm a notebook and handwriting fan, and still write down a lot of the important details of my life, but sometimes you just need to get something down when you don't have a physical pen and paper to hand. In the whirlwind of modern life, you might find out something important or be struck by inspiration at any moment. Even when you do manage to get it down, it'll be on a scrap of paper that's sometimes destined to never be seen again.
