# Protectimus SMART vs TOTP Authenticator

The clearest difference is rating: TOTP Authenticator at 4.8 against Protectimus SMART's 3.9. TOTP Authenticator also leads on update cadence (every 9 days vs every 7 months) and ratings volume (167 vs 18). Protectimus SMART's advantage is in-app purchases (none vs 4) and review sentiment (100% vs 65%). On price, ads and iOS requirement there is nothing between them.

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

TOTP Authenticator holds the better App Store score, 4.8 against 3.9. That said, the two scores are not equally well evidenced: TOTP Authenticator has 167 ratings behind it against 18, so its average is the more settled of the two. Written reviews complicate that: 100% of Protectimus SMART's written reviews are positive against 65% of TOTP Authenticator's, so the app with the better star average is not the one people write more warmly about.

Protectimus SMART ships an update every 7 months, TOTP Authenticator every 9 days. The most recent releases landed on September 24, 2026 and September 22, 2026 respectively.
