# Authenticator App vs PDF Editor

The clearest difference is rating: Authenticator App at 4.3 against PDF Editor's 3.9. Authenticator App also leads on ratings volume (210 vs 7) and review sentiment (67% vs 57%). PDF Editor's advantage is update cadence (every 9 days vs every 8 months) and iOS requirement (14 vs 17). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Authenticator App sells 15 in-app purchases, starting at $4.99 per 7 days and PDF Editor sells 11 in-app purchases, starting at $9.90 per 7 days. Whichever you choose, the download price is not the number that matters.

Authenticator App holds the better App Store score, 4.3 against 3.9. That said, the two scores are not equally well evidenced: Authenticator App has 210 ratings behind it against 7, so its average is the more settled of the two. Written reviews point the same way: 67% of Authenticator App's written reviews are positive against 57% of PDF Editor's.

Authenticator App ships an update every 8 months, PDF Editor every 9 days. The most recent releases landed on September 24, 2026 and July 30, 2026 respectively.
