# Authenticator vs eSign

The clearest difference is rating: Authenticator at 5.0 against eSign's 4.7. eSign's advantage is ratings volume (60 vs 7). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Authenticator sells 4 in-app purchases, starting at $6.99 per 7 days and eSign sells 1 in-app purchase, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Authenticator holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: eSign has 60 ratings behind it against 7, so its average is the more settled of the two.

Authenticator ships an update weekly, eSign every 5 days. The most recent releases landed on September 21, 2026 and September 19, 2026 respectively.
