I've been poking around on my iPhone, looking for a mobile gist editor that I can use to capture thoughts on the fly. Wound up downloading a couple and trying them out. I tried QuickGist first, but found it a little cumbersome for my big thumbs.
I ended up with OctoNote, which allows you to use it free for public gists, and has a subscription if you want to do private. I like this one a little better, so I'll play around with it and see if it sticks. If so, I'll kick in for the subscription so I can go 'dark mode'!
