Network Analyzer vs NetMaster

Network Analyzer is a free, easy-to-use network toolkit that turns your iPhone or iPad into a handy diagnostic instrument. Scan your network, discover every device connected to it, and troubleshoot connection problems in seconds - no technical background or extra hardware required. Built for curious home users and IT professionals alike, it packs a LAN device scanner, ping, traceroute, port scanner, DNS lookup, and whois into one clean, fast app. Try it for free, and upgrade to Network Analyzer Pro whenever you want advanced tools like traceroute visualization on the map, internet speed test, Wake on LAN, IP calculator, MAC address browser, and more. LAN scanner: - Fast and reliable detection of all network devices - IP addresses of all discovered devices - MAC addresses and vendor names of discovered devices - NetBIOS, mDNS (Bonjour), LLMNR, DNS, SNMP, and WS-Discovery name where available - Reachability (ping) test of discovered devices - IPv6 availability and discovered IPv6 addresses Ping & traceroute: - Round-trip delay including IP address and hostname for every network node - Country detection of the analyzed server - Support for both IPv4 and IPv6 Port scanner: - Scan common ports, custom port ranges, or the complete port range - Detection of closed, firewalled, and open ports - Description of the known open port services Whois: - Look up domains, IP addresses, and AS numbers - Support for both classic whois and the modern RDAP protocol DNS lookup: - Functionality similar to nslookup or dig - Query all record types at once or one specific type - Support for A, AAAA, CAA, CNAME, HINFO, LOC, MX, NAPTR, NS, PTR, SOA, SPF, SRV, SSHFP, TXT records Network information: - Default gateway, external IP (v4 and v6), DNS server, HTTP proxy - Wi-Fi network information such as SSID, BSSID, router vendor, security type, IP address (v4 and v6), and subnet mask - VPN, USB Ethernet, and personal hotspot connection details - Cell network information such as IP address and network type, with dual SIM support More: - Light and dark theme - Full IPv6 support everywhere - Detailed help - Regular updates

NetMaster helps explain slowdowns, instability, and intermittent dropouts without an account, ads, analytics, or tracking. RUN A COMPLETE NETWORK SCAN • Measure download and upload goodput with parallel HTTPS requests • See HTTPS latency, adjacent response-time variation, request failures, and a second latency vantage point • See confidence ranges and a p95 only when enough observations support it • Check direct UDP DNS response delivery across two providers, including bursts • Check latency under load and receive a bufferbloat grade • Compare everyday and first-time DNS response times • See the DNS transport observed for NetMaster’s measured request and compare resolver performance • Test real IPv4 and IPv6 reachability • Time the router hop and see whether added delay is local or farther upstream • Review public IP, ASN, egress region, TLS, HTTP, Wi-Fi security, captive-portal evidence, and tunnel indicators • Optionally install the bundled NetMaster Shortcut for connected iPhone Wi-Fi channel, standard, RSSI, noise, and RX/TX PHY rates — no compatible router or controller required • Watch live signal/noise, negotiated PHY rates, passive device traffic, and access-point changes • Compare the OS route gateway, Apple, Cloudflare, Google, and selected public-service latency graphs, rotating one probe at a time • Optionally select an M-Lab server for a separate single-flow route cross-check NARROW DOWN CONNECTION PROBLEMS Quick Diagnosis checks the path, router, internet, DNS, and responsiveness in sequence, then gives one likely explanation and a practical next step. INVESTIGATE INTERMITTENT DROPOUTS Run a 5-, 15-, or 30-minute monitor. On iOS 26, a user-started finite session can request lock-screen continuation; earlier versions must keep NetMaster visible. NetMaster records route changes, HTTPS heartbeats, gateway/DNS controls, IPv4/IPv6 evidence, latency changes, unknown gaps, and optional AP-roaming evidence. ESTIMATE ACTIVITY NEEDS Cautious assessments cover calls, 4K streaming, gaming, browsing, and uploads while naming the measured evidence and its limits. Protected history compares the same network over time, with a metrics-only mode. WATCH YOUR MAC FROM IPHONE Pair one iPhone to your Mac through private iCloud. See processor, memory, thermal, battery, and Mac traffic updates, 30-day history, eligible alerts, and PDF/CSV reports. Storage and low-storage findings remain visible only on the Mac. Remote speed tests require confirmation. BUILT FOR HONEST RESULTS A payload budget controls data use. Replenished parallel transfers target a stable window; when the cap ends a fast test too soon, the result is a lower bound, not a claimed maximum. Full-scan HTTPS timing is not ICMP ping; the separate live-latency board uses explicitly labeled ICMP echo. HTTPS adjacent response variation is not packet jitter; HTTPS request failures and UDP DNS response loss are not raw packet loss. PRIVACY BY DESIGN History stays in protected on-device storage. Optional Mac monitoring uses your private CloudKit database and no developer monitoring server. Reports leave only when you choose Share, with address redaction on by default. Important: Direct iOS app APIs omit exact radio values. The optional user-installed Shortcut uses Apple's Get Network Details action for connected RSSI, noise, channel, standard, and PHY rates; derived band can be ambiguous. Channel width, RF spectrum health, and cellular dBm are never invented. Wi-Fi identity needs permission. Balanced allows about 54.5 MB of throughput payload plus small requests and protocol overhead. Results are evidence, not proof that a router, carrier, VPN, or service is defective.
