# One Markdown vs Private Scan

The clearest difference is update cadence: Private Scan at every 2 days against One Markdown's monthly. One Markdown's advantage is iOS requirement (14.5 vs 17.0). 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 Private Scan sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.

One Markdown ships an update monthly, Private Scan every 2 days. Both last shipped on October 5, 2026.
