We also have a development team entirely focused on a new Web-based app to allow Day One to work in a web browser in an optimized way while remaining secure and encrypted.
We’re hard at work building a web-based version of Day One that will allow secure and encrypted journaling from within your favorite web browser like Safari, Chrome, or Firefox.
I’m happy with native apps. The macOS version did throw Markdown under a bus a few years back — and that made me stopped using it for anything not that is not Journaling.
I still remember Day One Publish — their weblog tool. That was micro.blog before microblog as a thing. Now that they are owned by Automattic, it would be cool to see some publishing integration with Wordpress — as a one-stop blog service.
