NetAnalyzer vs NoirShield

NetAnalyzer is a native network diagnostics app for iPhone and iPad. Diagnose slow or unstable connections, DNS issues, and local-network problems with clear summaries and technical details when you need them. NETWORK TOOLS • Network Info: View connection type, local and public IP addresses, DNS, gateway, and current Wi‑Fi connection information. • Connection Diagnostics: Check a target step by step through local connectivity, DNS, TCP, TLS, and HTTPS response. • Speed Test: Measure download, upload, idle and loaded latency, jitter, and packet loss with summary history. • Ping & Latency Monitoring: Track latency, packet loss, quality, and trends. • DNS Lookup: Query A, AAAA, CNAME, MX, TXT, NS, PTR, and SOA records using system DNS, UDP, DoT, or DoH resolvers. • TCP Port Scan: Test a single port or a common TCP port list. • Whois: Look up domain registration information. • Geo IP: Look up your current public IP or a submitted public IP address for network and approximate location details. • LAN Scan: Discover reachable IPv4 devices on your current local network, with Bonjour/mDNS service discovery. • IPv4 Subnet Calculator: Calculate CIDR, masks, broadcast addresses, and host ranges. PRO FEATURES • Traceroute: Display IPv4 routes and latency hop by hop. • Advanced TCP Port Scan: Scan custom and complete port ranges. • DNS Propagation: Compare DNS responses from 18 public resolvers queried directly from your device. • SSL/TLS Inspector: View certificate chains, system trust, SAN matching, protocol, cipher, and expiry status. • HTTPS Request Tester: Send requests and inspect headers, redirects, and response content. • Wi‑Fi Analysis: View current Wi‑Fi settings, gateway latency, and interface traffic. • Bluetooth Signal Analysis: Passively scan nearby BLE advertisements without connecting or pairing. • IP DNSBL Check: Query 20 built-in blocklists for IPv4 addresses. • No ads with Pro.

NoirShield is a network tool that runs entirely on your device. It encrypts your DNS lookups and can match them against blocklists stored on the device. Your traffic is never routed through a server of ours: there is nothing to relay it through, and your IP address does not change. ENCRYPTED DNS Resolve names over DNS-over-HTTPS or DNS-over-TLS. Choose from built-in encrypted resolvers or enter your own custom endpoint. Measure them on the network you are on and switch to the fastest. ON-DEVICE FILTERING Optional lists for ads and trackers, malware, phishing and crypto mining — 470,943 domains, matched on the device. Every list is off until you turn it on. You can import your own list and add your own allow and block rules, which take priority. DIAGNOSTICS Fourteen checks: reachability, IPv4 and IPv6, captive portals, latency, DNS resolution, DNS interception, DoH, DoT, HTTPS, TLS, QUIC, WebSocket and UDP. AUTOFIX Measures the network, applies a compatibility profile, verifies the result and remembers what worked for that network. NO ACCOUNT No sign-up, no sign-in, no subscription. Nothing about your lookups is uploaded. The activity log stays in memory and is gone when the app closes, unless you switch on "Keep activity after restart" in Settings. The app reaches our server for two things only: signed blocklist updates, and the connection tests while you are running diagnostics. NoirShield is not a country-switching VPN. It has no relay or proxy server, does not change your IP address and never decrypts HTTPS. On iPhone and iPad, iOS shows its own VPN badge whenever an on-device tunnel is running; NoirShield uses that tunnel only to hand DNS queries to the resolver on your device.
