iOS: When it comes to journaling apps on iPhone, it’s hard to beat Day One. Not everyone needs the complexity offered from Day One though, and if something a little simpler is more your thing, Ipsum is well worth a look.
Ipsum is structured like a chat app and basically works like a vertically scrolling notepad. When you open the app, all you see is your previous journal entry and a keyboard so you can get to typing as quickly as possible. That’s it. The whole point is to get your writing and that’s exactly what it does. You can’t export text, or search through it, or anything else, so you wouldn’t want to use this for thoughts of any importance, but when you just use a journal to write disposable garbage, Ipsum is a worthy choice.
