# DNS Optimizer vs AdGuard DNS

The clearest difference is rating: DNS Optimizer at 5.0 against AdGuard DNS's 3.7. AdGuard DNS's advantage is in-app purchases (none vs 2) and review sentiment (36% vs 25%). On price, update cadence, ads and device support there is nothing between them.

Both are free to download. DNS Optimizer sells 2 one-off in-app purchases. AdGuard DNS asks for nothing beyond the download.

DNS Optimizer holds the better App Store score, 5.0 against 3.7. That said, the two scores are not equally well evidenced: AdGuard DNS has 35 ratings behind it against 7, so its average is the more settled of the two. Written reviews complicate that: 25% of DNS Optimizer's written reviews are positive against 36% of AdGuard DNS's, so the app with the better star average is not the one people write more warmly about.

DNS Optimizer ships an update every 11 days, AdGuard DNS every 2 weeks. The most recent releases landed on September 11, 2026 and September 14, 2026 respectively.
