# PDF Scanner vs Authenticator

The clearest difference is ads: PDF Scanner at none against Authenticator's shown. PDF Scanner also leads on ratings volume (243 vs 25). Authenticator's advantage is update cadence (weekly vs fortnightly) and iOS requirement (14.0 vs 16.0). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. PDF Scanner sells 3 in-app purchases, starting at $6.99 per 7 days and Authenticator sells 3 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 — 4.4 for PDF Scanner against 4.5 for Authenticator. That said, the two scores are not equally well evidenced: PDF Scanner has 243 ratings behind it against 25, so its average is the more settled of the two.

PDF Scanner ships an update fortnightly, Authenticator weekly. The most recent releases landed on September 17, 2026 and September 5, 2026 respectively.
