# MermaidEditor vs Markdown Editor and Reader

The clearest difference is price: Markdown Editor and Reader at Free against MermaidEditor's $3.99. MermaidEditor's advantage is rating (2.3 vs 1.0) and chart position (#112 vs unranked). On review sentiment, update cadence, ads and in-app purchases there is nothing between them.

Markdown Editor and Reader is free to download; MermaidEditor costs $3.99 up front. Neither carries in-app purchases, so what you see is what you pay.

MermaidEditor holds the better App Store score, 2.3 against 1.0. That said, the two scores are not equally well evidenced: MermaidEditor has 10 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 14% of MermaidEditor's written reviews are positive against 18% of Markdown Editor and Reader's, so the app with the better star average is not the one people write more warmly about.

MermaidEditor ships an update every 3 weeks, Markdown Editor and Reader fortnightly. The most recent releases landed on September 21, 2026 and September 22, 2026 respectively.
