# One Scan vs PDF Scanner Documents

The clearest difference is monetization model: One Scan at freemium against PDF Scanner Documents's subscription. One Scan also leads on ratings volume (12K vs 59). PDF Scanner Documents's advantage is update cadence (every 3 days vs every 2 months) and iOS requirement (14.0 vs 26.0). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. One Scan sells 10 in-app purchases, starting at $3.99 per 7 days and PDF Scanner Documents sells 5 in-app purchases, starting at $4.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.7 for One Scan against 4.7 for PDF Scanner Documents. That said, the two scores are not equally well evidenced: One Scan has 12K ratings behind it against 59, so its average is the more settled of the two. Written reviews are what separate them: 26% of One Scan's written reviews are positive against 20% of PDF Scanner Documents's.

One Scan ships an update every 2 months, PDF Scanner Documents every 3 days. Both last shipped on September 25, 2026.
