Customer Reviews

functional, performant, beautiful

iA Writer handles all my Markdown documents confidently - without glitches; without degraded performance for even very large documents that include many images; with beautiful and very functional typography.

If compared to all other Markdown editors i've tested it deserves 5 stars - so this is what i'm giving it. That doesn't mean i wouldn't like to see a few enhancements, though:
1. Layout in full-screen mode is a work of beauty - but it wastes line width, which makes me lose context and orientation in very large documents. It also means that Markdown tables are often broken across lines, which makes them even harder to comprehend than usual. Because there are no "Preferences" in iA Writer (normally a feature, not a bug) i can't customize (increase) line length or (reduce) margin width in full-screen mode. This is the one shortcoming that keeps motivating me to search for better alternatives (without success so far).
2. No support for other Markdown dialects than MultiMarkdown - whereas i'd often need an editor to write GitHub-flavoured Markdown, pandoc Markdown, etc.
3. Just one formatting style. Especially for large documents it would be very helpful to have the option to (auto-) number headings, or to change their colour, but iA Writer just has one (gorgeous and very refined) style that must fit all documents...

My Go-To App for all text composition

If I am draughting an email, or a blog, or a piece of written design work, it always begins in iA Writer. The interface is simple and uncluttered, and I find I can work much more quickly than I can in more complicated apps like MS Word, or Pages. It is a treat to use, and has replaced all of the other plain text apps I tried along the way. If you want a simple text app that won’t have you distracted and fiddling with formatting instead of getting on with the writing… Buy this one!

Does exactly what it says

A fast, reliable app, whoch does exactly what it says.

I use it most days, either for jotting down ideas or writing blog posts. In many ways, I can get a similar, uncluttered experience using the "distraction free” modes of other word processors, yet I keep returning to iA Writer. That says a lot.
