# AuthGuard vs HVAC

The clearest difference is rating: AuthGuard at 5.0 against HVAC's 4.3. HVAC's advantage is ratings volume (6 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. AuthGuard sells 3 in-app purchases, starting at $9.99 per 7 days and HVAC sells 3 in-app purchases, starting at $9.99 per 7 days. Whichever you choose, the download price is not the number that matters.

AuthGuard holds the better App Store score, 5.0 against 4.3. That said, the two scores are not equally well evidenced: HVAC has 6 ratings behind it against 1, so its average is the more settled of the two.

AuthGuard ships an update every 10 days, HVAC every 11 days. The most recent releases landed on October 31, 2026 and November 6, 2026 respectively.
