Screenshots 
Open any Markdown file and see it rendered with full GitHub Flavored Markdown support. Headings, lists, tables, task lists, footnotes, and horizontal rules all display exactly as intended.
Mermaid diagrams render inline. Flowcharts, sequence diagrams, class diagrams, state charts, ER diagrams, and more. LaTeX math expressions render with KaTeX for fast, accurate mathematical notation.
Code blocks get full syntax highlighting. Dark mode adapts automatically. Live reload watches for file changes. Everything runs locally on your Mac.
Is my data collected or shared?
No. All apps run 100% locally on your Mac. No analytics, no tracking, no data sent to servers. Your privacy is guaranteed.
Is this a subscription?
No. All apps are one-time purchases. Pay once, use forever. No recurring fees, no hidden costs.
What if I don't like the app?
Apple offers full refunds within 14 days of purchase, no questions asked. Request a refund directly through the App Store if you're not satisfied.
Does it slow down my Mac?
No. All apps are native SwiftUI with minimal resource usage. Menu bar monitoring uses negligible CPU and memory.
Which macOS version do I need?
Most apps require macOS 14 (Sonoma) or later. Check the specific app page for exact requirements. Works on both Intel and Apple Silicon Macs.
