I used to use Ulysses. It's a great app, but shortly after I paid $40 for it, they switched to subscription. I'm now looking for a new app. I use Mac for work (with the old no longer updated Ulysses) Linux at home (using caret) And an Android phone (JotterPad). I sync between them using Dropbox. Once Ulysses stops working on a future MacOS update, I'll likely switch to caret there as well. It's relatively easy to get a really nice, supported polished Mac app. Working in a cross platform world is tough. I'd love to be able to replace Ulysses and caret with a native Markdown editor like this. I'll check it out.
