# One Markdown vs Simark

The clearest difference is update cadence: Simark at every 2 days against One Markdown's monthly. Simark also leads on rating (5.0 vs 4.6). One Markdown's advantage is ratings volume (141 vs 1). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. One Markdown sells 3 in-app purchases, starting at $3.99 per year and Simark sells 2 in-app purchases, starting at $1.19 per month. Whichever you choose, the download price is not the number that matters.

Simark holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: One Markdown has 141 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 82% of One Markdown's written reviews are positive against 75% of Simark's, so the app with the better star average is not the one people write more warmly about.

One Markdown ships an update monthly, Simark every 2 days. The most recent releases landed on September 21, 2026 and September 23, 2026 respectively.
