Make your DNS private. DNS Security helps protect your privacy by encrypting DNS queries with DNS over HTTPS (DoH) and DNS over TLS (DoT). Choose a provider, enable your DNS configuration, and manage your settings in one place—without routing your internet traffic through a VPN. WHY ENCRYPT YOUR DNS? HTTPS protects the content exchanged with websites, but traditional DNS lookups may still be unencrypted. These lookups translate domain names into IP addresses and can reveal the domains your device requests. Encrypted DNS helps protect queries between your device and your chosen DNS provider from eavesdropping and tampering. Your provider still handles those queries, so choose one whose privacy practices you trust. EVERYDAY DNS CONTROL • Use DNS over HTTPS or DNS over TLS. • Choose built-in profiles for providers including Cloudflare, Google, and AdGuard. • Enable or disable your DNS configuration from the app. • Choose whether DNS settings apply on Wi-Fi, cellular, or both. • Check DNS protocol and provider details in the Status tab. DNS SECURITY OR DNS SECURITY PRO? DNS Security includes the everyday DNS controls above at no cost. It offers an optional Pro in-app purchase for the advanced features below. DNS Security Pro is the paid edition. It includes the same everyday DNS controls plus these advanced features from the start: PRO FEATURES (IN APP PURCHASE) • Create custom DoH and DoT profiles. • Download updates to built-in DNS profiles. • Enable or disable DNS for specific Wi-Fi SSIDs. • Switch profiles with Shortcuts and URL schemes. The difference is advanced control: both editions support encrypted DNS. You can unlock the Pro tools inside DNS Security or choose DNS Security Pro with those tools already included. DESIGNED AROUND PRIVACY DNS Security manages your device's DNS configuration and does not collect personal information. DNS requests are handled by your selected provider under that provider's privacy policy. Encrypted DNS protects DNS queries; it does not make all browsing anonymous. Blocking malicious domains depends on the provider and profile you choose. AUTOMATE YOUR DNS With Pro, use Shortcuts or a compatible app to open a switch URL and select a DNS profile with your preferred network settings. Example: select google-DOH for Wi-Fi, with cellular disabled: dnsapp://switch?config=google-DOH&enableOnWifi=true&enableOnCellular=false Use the scheme for your installed app: • DNS Security Pro: dnssecuritypro:// • DNS Security: dnssecurity:// • Shared scheme: dnsapp:// Replace dnsapp in the example with your app's scheme. The requested profile must already exist in the app. Initial activation may require selecting DNS Security in iOS Settings. Choose your DNS. Control your settings. Add privacy to every lookup that uses your encrypted DNS configuration.

Verdict
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.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
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.
