Even though I am not writing that much, I am weirdly picky about choosing and sticking to a font for my ‘writing environment’.
Much to my own annoyance I tend to switch fonts regularly but these are the fonts that I like best:
Hack My current favourite. I have re-discovered Hack a few weeks ago, but once I got used to it, I came to like it and have been using it happily ever since in every app.
Fira Mono This is one very nice and I have become rather attached to this one. The only thing I am missing is italics. Atom.io is somehow able to fake them, which makes the lack thereof less obvious, but doesn’t help in other apps. There is though a _non-official-fork_ of the font including italics which I might give a try one day.
Nitti Without doubt a long time favourite. It ships with iA Writer, but the standalone version is a tad too expensive for me. I simply can’t justify paying that much for any font, hence I use it only when I use iA Writer.
