This year Editorial dethroned Byword as my main writing app. I don't use 1% of its available power but the few extras make it all worthwhile. (For example, the ability to dump a random idea at the bottom of a document without leaving where I'm currently typing.) I have some visual problems that make reading black text on a white background irritating (Thanks a lot, iOS 7) so a dark mode is mandatory and Editorial has a great looking one: off-white on dark navy. (Too many app's dark mode is just white text on a black background, which is harsh to look at and highlights every fingerprint smudge) There's no iPhone version so I'm using Byword on my iPhone to access my scripts on the rare occasions I want to edit them on the go.
