# SpyRadar vs Authenticator

The clearest difference is ads: Authenticator at none against SpyRadar's shown. Authenticator also leads on update cadence (every 4 days vs every 11 days). SpyRadar's advantage is ratings volume (156 vs 8). On price, rating, 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 Authenticator sells 3 in-app purchases, starting at $6.99 per 7 days. Whichever you choose, the download price is not the number that matters.

On the App Store both sit at effectively the same score — 4.5 for SpyRadar against 4.5 for Authenticator. That said, the two scores are not equally well evidenced: SpyRadar has 156 ratings behind it against 8, so its average is the more settled of the two.

SpyRadar ships an update every 11 days, Authenticator every 4 days. The most recent releases landed on October 16, 2026 and October 17, 2026 respectively.
