# One Scan vs PDF

The clearest difference is ads: One Scan at none against PDF's shown. One Scan also leads on rating (4.7 vs 4.4) and ratings volume (12K vs 1.4K). PDF's advantage is review sentiment (60% vs 26%) and iOS requirement (15.0 vs 26.0). On price, update cadence, in-app purchases and monetization model 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 sells 8 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.

One Scan holds the better App Store score, 4.7 against 4.4. That said, the two scores are not equally well evidenced: One Scan has 12K ratings behind it against 1.4K, so its average is the more settled of the two. Written reviews complicate that: 26% of One Scan's written reviews are positive against 60% of PDF's, so the app with the better star average is not the one people write more warmly about.

One Scan ships an update every 2 months, PDF every 6 weeks. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
