Bear and Ulysses, while nice, do not do what OP is talking about (unless they just did an update I’m not aware of).

Both of these apps do not abstract away the markup after a word is typed. This is the killer feature of Typora, along with the ability to completely redesign the entire editor yourself with a custom style sheet (along with awesome image management).

Typora has completely taken over my markdown workflow because of this.

I’ve tried Bear, Ulysses, IA writer, and countless others. None have this clever blended preview like Typora.

I've used Typora and enjoyed it, but I've learned that I really dislike this abstracting away of the Markdown. I'm glad it exists though — and it's a really excellent product for those who enjoy this feature.

Bear does it (just less elegantly)

My understanding is they store everything in SQLite. Their business strategy is to charge for sync (although manual export is free)

Given that it is branded as a note taking application it makes sense both from a business and implementation point of view.

Bear also kinda uses its own rendering for some things. Like dashes turn into checkboxes rather than unordered lists. Again, for a note app, checkboxes are really neat!

I’ve been using it for 2-3 month and really like it!
