It's not as though there's any shortage of note taking applications these days, but they usually seem to need so much commitment. (pick which one to use, create an account, have your notes cloud synced, etc.) Back when I used Windows, I would use Notepad to essentially take scrap notes, write to-do lists, write a quick plan, that kind of thing. I don't need or want the notes to last forever, I just want to start with a blank page, assemble a few thoughts, and click X when I don't need it anymore. So I made Temporary Note. It's a scratch pad for anything you want to quickly jot down, whether it's a shopping list, an idea, a phone number, or anything else, really.
