# One Markdown vs MD Flow

The clearest difference is rating: One Markdown at 4.6 against MD Flow's 1.0. One Markdown also leads on ratings volume (141 vs 1) and iOS requirement (14.5 vs 17.0). MD Flow's advantage is monetization model (free vs free with in-app purchases) and update cadence (every 9 days vs monthly). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. One Markdown sells 3 in-app purchases, starting at $3.99 per year and MD Flow sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

One Markdown holds the better App Store score, 4.6 against 1.0. 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.

One Markdown ships an update monthly, MD Flow every 9 days. The most recent releases landed on October 5, 2026 and October 4, 2026 respectively.
