# Authenticator App vs File & PDF Converter

The clearest difference is ads: Authenticator App at none against File & PDF Converter's shown. File & PDF Converter's advantage is ratings volume (43 vs 5) and iOS requirement (14.0 vs 17.6). On price, rating, update cadence and in-app purchases there is nothing between them.

Both are free to download. Authenticator App sells 2 in-app purchases, starting at $6.99 per 7 days and File & PDF Converter sells 3 in-app purchases, starting at $6.99 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 — 4.8 for Authenticator App against 4.7 for File & PDF Converter. That said, the two scores are not equally well evidenced: File & PDF Converter has 43 ratings behind it against 5, so its average is the more settled of the two.

Both ship on a similar rhythm, roughly every 3 days. The most recent releases landed on September 10, 2026 and September 8, 2026 respectively.
