Here's something interesting - The guys over at iA (devleopers of the iA Writer app), have made their own font. Prevously the apps used a font called Nitti, which kind of became part of the iA brand, but they took it upon themselves to develop a more writing focussed option.
Hell just froze over. After seven years of offering no font options to write, iA Writer now comes with a choice. Next to the monospace Nitti you will now find a brand new duospace font. Duospace?
For an app that was designed as the digital equivalent of a typewriter, a monospace font is not a far fetch. But, if font choice were just a matter of style, there are better and less expensive ways to impress than leasing a high end monospaced typeface that many take for a silly Courier.
There was clearly a lot of investigastion that went into it, and I'm a fan of the results!
