# DNS Security vs DNS Optimizer

The clearest difference is review sentiment: DNS Security at 67% against DNS Optimizer's 25%. DNS Security also leads on ratings volume (72 vs 7). DNS Optimizer's advantage is rating (5.0 vs 4.8). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. DNS Security sells 1 one-off in-app purchase and DNS Optimizer sells 2 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

DNS Optimizer holds the better App Store score, 5.0 against 4.8. That said, the two scores are not equally well evidenced: DNS Security has 72 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 67% of DNS Security's written reviews are positive against 25% of DNS Optimizer's, so the app with the better star average is not the one people write more warmly about.

DNS Security ships an update every 3 weeks, DNS Optimizer every 11 days. The most recent releases landed on September 23, 2026 and September 11, 2026 respectively.
