WiFi Sucks vs NetMaster

WiFi Sucks is the brutally honest WiFi speed test that tells you exactly how your connection is performing — in plain English. No jargon, no fluff, no ads. ONE-TAP SPEED TEST Tap one button to measure download speed, upload speed, ping, and jitter against Cloudflare’s global edge network. Results appear in seconds with a clear grade: Excellent, Good, Fair, Poor, or Terrible. PLAIN ENGLISH DIAGNOSIS We don’t just throw numbers at you. WiFi Sucks tells you if your connection is fast enough for Netflix, Zoom calls, online gaming, and more — and if it’s not, we explain exactly why and what you can do about it. WIFI OPTIMIZER (Pro) Get personalized, actionable tips based on your actual test results. One-tap buttons open your WiFi settings, detect your router, test DNS providers, and apply the fastest DNS automatically. NETWORK SCANNER (Pro) See every device connected to your WiFi. Identifies phones, computers, smart TVs, printers, IoT devices and more using multi-port scanning and Bonjour discovery. Find out who’s hogging your bandwidth. PING MONITOR (Pro) Live latency graph that pings multiple servers simultaneously. Track jitter, packet loss, and connection stability in real time. Perfect for diagnosing gaming lag or video call drops. DNS SPEED TESTER (Pro) Test Cloudflare, Google, Quad9, OpenDNS, and AdGuard DNS from your location. Apply the fastest one to your device with a single tap using DNS-over-HTTPS. SPEED REQUIREMENTS CHECK (Pro) See exactly which activities your connection supports. Green, yellow, or red indicators for 12 common activities from web browsing to 4K streaming. TRACK YOUR SPEEDS Every test is saved automatically. View your speed history with beautiful trend charts to see if your ISP is delivering what you pay for. FREE TO USE Run 3 speed tests per day for free. Upgrade once — no subscription — to unlock unlimited testing and all premium tools. No ads. No tracking. No subscriptions. Just honest speed tests.

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.
