### 2/5 — Constantly Crashing

*2026-08-24*

When it works, it works wonderfully. But lately I cannot open .md files without the app crashing. Often times I can’t even get it to work at all.

### 4/5 — Just what I needed

*2026-08-03*

This app is great, it is a terrific Markdown renderer and editor. I use a monospace font for this editor and it would be great if I could specify a Document mode font different from Editor mode.

### 5/5 — FINALLY

*2026-05-24*

This is what I’ve been looking for. Simple, native, renders nicely, no bloated features I don’t care about. The ONLY thing I’d like to see is in-line editing and rendering in the same view.

### 5/5 — Quick & Lightweight

*2026-04-17*

Beautiful markdown app. Lighting fast with new modern MacOS features like QuickLook built right in. Love the formatting - just works !

### 3/5 — Syntax Highlighting

*2026-03-23*

The app is nice and feel native, but for a PAID app not having syntax highlighting for code blocks is crazy…

### 5/5 — Nice and Light

*2026-03-22*

Opens Quick, fast easy edits and no bloat! Love it.

### 5/5 — Love the app, and one small request

*2026-03-20*

This app is fantastic, and I love that it’s so light and native. One small request: it would be great to have a keyboard shortcut to toggle between view modes, in addition to cmd-1 and cmd-2. Keep up the great work!
