# SymEditor vs One Markdown

The clearest difference is review sentiment: One Markdown at 82% against SymEditor's 0%. One Markdown also leads on rating (4.6 vs 4.0) and ratings volume (141 vs 2). SymEditor's advantage is iOS requirement (11.0 vs 14.5). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. SymEditor sells 3 in-app purchases, starting at $1.99 per month and One Markdown sells 3 in-app purchases, starting at $3.99 per year. Whichever you choose, the download price is not the number that matters.

One Markdown holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: One Markdown has 141 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 0% of SymEditor's written reviews are positive against 82% of One Markdown's.

Both ship on a similar rhythm, roughly monthly. The most recent releases landed on June 1, 2026 and September 21, 2026 respectively.
