The calm way to read and write Markdown.

"Honestly I'd been wanting this for years. Hit space on a .md in Finder and it's just there, rendered properly — no app to wait for. I must use it 30 times a day now and barely notice I'm doing it."

"Wrote up our release notes, hit Publish, and had a link to drop in our team chat a second later. A teammate opened it on her phone and it looked exactly like my screen — no sign-in, nothing to set up. That's the dream."

"My READMEs are a mess of Swift, Python and a couple of mermaid diagrams. This is the first app where the diagrams actually look good instead of like an afterthought — and the code colours are spot on too."

"It just stays out of the way. No panels shouting for attention, no upsell popups — I open a file, read it, close it. That's the whole point and QuickMark nails it."

"I review PRs and READMEs all day. Being able to glance at a Markdown file without launching anything heavy has quietly become muscle memory. Small thing, huge over a week."

"You can tell someone who actually uses a Mac built this. The little things — Quick Look, the typography, a dark mode that isn't harsh — all just feel right."

"Runbooks, incident notes, YAML — all readable and highlighted, and it works on a plane with no wifi. It's on my Mac and iPad and just stays in sync with how I work."

"The inline math finally renders the way I write it, so my notes with equations don't look broken anymore. And a big document opens instantly, which genuinely surprised me."

"It feels designed, not assembled. The light theme is genuinely calm and the dark mode is soft rather than black-hole harsh — which is rare for a developer tool."
