I love using apps of all kinds and, to be honest, to do apps are what made me used to writing to dos in the first place. Otherwise I just used to keep tasks in my head because writing in a book was so boring.
However, now that I am used to making lists, I need more features than what they provide.
I mostly use Evernote for storing links and images which would otherwise be in a hundred different places. For all important stuff like daily tasks and long term goals, I have gone fully analogue.
What’s your app like, is it available for consumers? 😉
