# PDF Editor vs Authenticator

The clearest difference is ads: Authenticator at none against PDF Editor's shown. Authenticator also leads on update cadence (every 4 days vs every 8 days). PDF Editor's advantage is ratings volume (88 vs 9). On price, rating, in-app purchases and monetization model there is nothing between them.

Both are free to download. PDF Editor sells 3 in-app purchases, starting at $4.99 per 7 days and Authenticator 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 — 4.5 for PDF Editor against 4.4 for Authenticator. That said, the two scores are not equally well evidenced: PDF Editor has 88 ratings behind it against 9, so its average is the more settled of the two.

PDF Editor ships an update every 8 days, Authenticator every 4 days. The most recent releases landed on November 14, 2026 and November 4, 2026 respectively.
