Show HN: Smackdown: Markdown Viewer for macOS, Fast, Fluid, and Free

https://apps.apple.com/us/app/smackdown-markdown-viewer/id6747908871?mt=12
1•k_badcommand•7h ago
Hey all, I'm the Founder & Developer at Bad Command AI, and I'm really excited to share this project with you all!

Smackdown on macOS App Store is now available.

Experience markdown like never before. Beautiful themes, native tabs, and blazing fast performance make reading documentation a joy on your Mac.

Supports light and dark themes, and a very special cyberpunk theme (because why not?).

We just pushed out an update today that adds fluid zooming, dynamic fonts with scaling, and a new wide mode function to expand the view for ultrawide and high resolution monitors.

Lots more to come, we want this to be the very best Markdown viewer available on the Mac platform!

Full disclosure, I am the developer of this project.

I really appreciate the Hacker News community and thank you all for any interest you may have in our humble app!
