# iScanner vs Scan to PDF

The clearest difference is ads: Scan to PDF at none against iScanner's shown. Scan to PDF also leads on iOS requirement (16.0 vs 18.0). iScanner's advantage is review sentiment (82% vs 48%) and ratings volume (1.4M vs 24K). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. iScanner sells 9 in-app purchases, starting at $3.99 per 7 days and Scan to PDF sells 9 in-app purchases, starting at $3.99 per month. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.8 for iScanner against 4.7 for Scan to PDF. That said, the two scores are not equally well evidenced: iScanner has 1.4M ratings behind it against 24K, so its average is the more settled of the two. Written reviews are what separate them: 82% of iScanner's written reviews are positive against 48% of Scan to PDF's.

iScanner ships an update fortnightly, Scan to PDF every 2 months. Both last shipped on November 12, 2026.
