# SpyRadar vs Auth Authenticator

The clearest difference is ads: Auth Authenticator at none against SpyRadar's shown. Auth Authenticator also leads on rating (4.9 vs 4.4) and device support (3 vs 1). SpyRadar's advantage is update cadence (every 11 days vs every 5 weeks) and ratings volume (157 vs 28). On price, review sentiment, in-app purchases and monetization model there is nothing between them.

Both are free to download. SpyRadar sells 3 in-app purchases, starting at $3.99 per 7 days and Auth Authenticator sells 2 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Auth Authenticator holds the better App Store score, 4.9 against 4.4. That said, the two scores are not equally well evidenced: SpyRadar has 157 ratings behind it against 28, so its average is the more settled of the two. Written reviews point the same way: 95% of SpyRadar's written reviews are positive against 100% of Auth Authenticator's.

SpyRadar ships an update every 11 days, Auth Authenticator every 5 weeks. The most recent releases landed on October 20, 2026 and October 19, 2026 respectively.
