DNS Survey vs AdsBlockers

DNS Survey reads a domain's public DNS records and explains, in plain English, how that domain handles email. Type a domain and you get: • A plain-English summary — who hosts the mailboxes, whether sender authorisation (SPF) is published, whether an anti-spoofing policy (DMARC) is in place and how strict it is, and whether outgoing mail is signed (DKIM). • Third-party senders — the outside services allowed to send email as that domain, with the evidence for each. Shared sending platforms are labelled separately, because they prove mail is being sent without revealing which application sends it. • Vendors by category — products the domain shows evidence of using, from mailbox hosting and CRM to payments, security and developer tools, each shown with the record that identified it. • The raw records — SPF, DMARC, MX, NS, CNAME, A, TXT and DKIM, including SPF lookup-limit counting and DMARC policy warnings. Touch and hold to copy any value. Everything comes from public DNS. The app never connects to mail servers, sends email, or asks for credentials. Nothing is stored. No history, no cache, no account — a result exists only while you are looking at it. Detection is best-effort: a match on a verification token means the domain was verified with that service at some point, not that it is in use today.

AdsBlockers is a device-wide ad and tracker blocker for iPhone and iPad. It works at the DNS level, so ads are blocked system-wide — in apps, browsers, and anywhere else your device makes network requests. How it works When an app on your device tries to resolve a domain name (like a tracking or ad-serving server), the DNS proxy checks it against locally stored blocklists. If the domain is blocked, the request is silently dropped — the ad never loads. If it's allowed, the query is forwarded to your chosen DNS resolver over encrypted DNS-over-HTTPS. The included Safari content blocker adds a second layer of protection specifically for web browsing inside Safari, catching cosmetic and path-level ad rules that DNS-only blocking can't reach. What's included — Filter lists from EasyList, EasyPrivacy, StevenBlack hosts, OISD, AdGuard DNS filter, and 1Hosts Lite. Toggle each list on or off independently. — Custom allowlist and blocklist for per-domain control. — Pause protection temporarily (or until you turn it back on). — Kill switch stops all internet if the DNS filter loses resolver access, preventing unfiltered traffic. — Daily blocked-count charts and a 7-day activity log on the Activity screen. Your privacy Nothing leaves your device. There are no accounts, no analytics, and no server logs. The only third-party DNS resolver you interact with is the one you choose — Cloudflare, Google, Quad9, or AdGuard DNS. Queries are encrypted by default via DNS-over-HTTPS. The app cannot see your browsing content, search history, usernames, or passwords — only the domain names in DNS queries, and only those that were blocked appear in the local activity log (kept for 90 days). Requirements iOS 18 or later. A physical iPhone is required to use the DNS proxy; the Safari content blocker works on iPad without one.
