# TOTP Authenticator vs Argus

The clearest difference is review sentiment: Argus at 100% against TOTP Authenticator's 36%. Argus also leads on in-app purchases (none vs 2) and update cadence (every 3 days vs every 2 months). TOTP Authenticator's advantage is rating (4.7 vs 3.3) and ratings volume (3.9K vs 3). On price and ads there is nothing between them.

Both are free to download. TOTP Authenticator sells 2 one-off in-app purchases. Argus asks for nothing beyond the download.

TOTP Authenticator holds the better App Store score, 4.7 against 3.3. That said, the two scores are not equally well evidenced: TOTP Authenticator has 3.9K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 36% of TOTP Authenticator's written reviews are positive against 100% of Argus's, so the app with the better star average is not the one people write more warmly about.

TOTP Authenticator ships an update every 2 months, Argus every 3 days. Both last shipped on October 24, 2026.
