About

Stay Secure & Ad Block

Features
Read full description

Fewer unwanted connections. More control over your browsing. Stay Secure & Ad Block is a DNS filtering and privacy utility that helps reduce unwanted connections while you browse and use supported apps. It blocks DNS requests to known advertising, tracking, phishing, scam, and malicious domains included in your active protection lists and rules. DNS PROTECTION Filter requests to listed domains at the DNS level, before a connection is established through that lookup. AD BLOCKING Reduce connections to known advertising domains across supported apps and websites. TRACKER BLOCKING Help limit connections to known tracking and analytics domains. PHISHING & SCAM DOMAIN BLOCKING Block requests to domains identified in the active lists as phishing or scam sites. MALICIOUS DOMAIN BLOCKING Block requests to domains associated with known malicious activity when they match the filtering rules. YOUR RULES, YOUR CONTROL With Premium, add domains to a custom blocklist and allow trusted domains with an allowlist. Kids Mode restricts access to allowlisted domains and their subdomains. Set up your trusted sites before enabling it. SEE YOUR PROTECTION AT WORK Check protection status, blocking statistics, and recent blocked domains in one place. Enable protection, approve the configuration requested by iOS, and confirm that protection is active. Keep protection-list updates enabled to receive available rule updates. FREE & PREMIUM Start with an essential ad and tracker protection list, statistics, and limited recent activity. Premium adds expanded lists, custom rules, an allowlist, Kids Mode, and access to the retained activity history. DNS filtering works with supported network traffic. It cannot block every ad or harmful connection, including content served from the same domains as content you want to view. Coverage depends on the active lists, apps, and network settings. The app filters domains; it does not scan files or remove malware. Premium is an auto-renewing subscription. Review the price and billing period before purchasing. Manage or cancel your subscription in your App Store account settings.

About

DNSimple

Features
Read full description

DNSimple gives you control over DNS on iPhone and iPad through a local DNS tunnel. Use encrypted DNS-over-HTTPS by default, choose from Cloudflare, Google, Quad9 and AdGuard presets, or enter your own resolver. The dashboard shows the active configuration, resolver health and the last responding resolver. PRIVATE HISTORY, YOUR CHOICE Recording is optional and off by default. Keep records on your device with iOS file protection and backup exclusion, or choose memory-only history that disappears when recording stops or the tunnel ends. Choose a retention period of 1 hour, 24 hours, 7 days or 30 days. Expired records are removed while running or when you next open the app. Switching storage clears existing history. UNDERSTAND YOUR DNS Search and filter requests by domain, resolver, query type, errors, local overrides or unencrypted transport. Inspect DNS response codes, response times and the actual responding resolver. Statistics show the retained history window, with up to 20,000 on-device records or 2,000 memory-only records. CONTROL YOUR RESOLVER - DNS-over-HTTPS with HTTPS certificate validation - Standard DNS with UDP and TCP support - Custom IPv4 and IPv6 DNS servers - Custom hosts overrides - Live recording controls and resolver health checks - Plaintext fallback disabled unless you explicitly enable it DNSimple does not require an account and has no advertising or analytics. DNS history stays on your device. Selected bootstrap servers resolve the DoH endpoint hostname; website DNS queries use HTTPS unless you enable plaintext fallback. Your selected resolver can see the queries it handles. DNSimple changes system DNS. It does not hide your IP address or encrypt other app traffic. Apps using their own DNS can bypass the tunnel and will not appear in history. When disconnected, iOS uses its normal DNS settings.
