i just wrote a few thoughts down on the journal app on a whim, and i actually liked it.
i think it's worth installing and saving for later. i know the notes app essentially does the same thing, but mine is a mess, and this one's distraction-free.
the next time you have a musing, open the app and write it down, just to see how it makes you feel. you might find yourself wanting to make a habit of it, like i did. i think it'd be cool to revisit the journal entries i've accumulated over time.
