# Argus vs TOTP Authenticator

The clearest difference is in-app purchases: Argus at none against TOTP Authenticator's 4. Argus also leads on review sentiment (100% vs 66%) and update cadence (every 3 days vs every 11 days). TOTP Authenticator's advantage is ratings volume (174 vs 2) and rating (4.7 vs 4.5). On price, ads and device support there is nothing between them.

Both are free to download. TOTP Authenticator sells 4 in-app purchases, starting at $5.99 per 7 days. Argus asks for nothing beyond the download.

TOTP Authenticator holds the better App Store score, 4.7 against 4.5. That said, the two scores are not equally well evidenced: TOTP Authenticator has 174 ratings behind it against 2, so its average is the more settled of the two. Written reviews complicate that: 100% of Argus's written reviews are positive against 66% of TOTP Authenticator's, so the app with the better star average is not the one people write more warmly about.

Argus ships an update every 3 days, TOTP Authenticator every 11 days. The most recent releases landed on October 3, 2026 and October 17, 2026 respectively.
