# PDF Scanner Document Converter vs Authenticator App

The clearest difference is monetization model: PDF Scanner Document Converter at free with in-app purchases against Authenticator App's subscription. PDF Scanner Document Converter also leads on rating (4.5 vs 4.1) and ratings volume (534 vs 9). Authenticator App's advantage is ads (none vs shown) and update cadence (daily vs every 2 weeks). On price, in-app purchases, device support and iOS requirement there is nothing between them.

Both are free to download. PDF Scanner Document Converter sells 5 in-app purchases, starting at $9.99 per month and Authenticator App sells 2 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

PDF Scanner Document Converter holds the better App Store score, 4.5 against 4.1. That said, the two scores are not equally well evidenced: PDF Scanner Document Converter has 534 ratings behind it against 9, so its average is the more settled of the two. Written reviews complicate that: 32% of PDF Scanner Document Converter's written reviews are positive against 50% of Authenticator App's, so the app with the better star average is not the one people write more warmly about.

PDF Scanner Document Converter ships an update every 2 weeks, Authenticator App daily. The most recent releases landed on September 25, 2026 and September 17, 2026 respectively.
