NetPulse Diagnostics vs NHCheck Lite

NetPulse Diagnostics is a clean network troubleshooting toolkit for iPhone and iPad. It helps developers, system administrators, website owners, support teams and everyday users understand what is happening with their connection. Check your network without guessing: • View Wi-Fi, cellular, VPN and network path status • Inspect local interfaces visible to iOS • Run DNS lookup and DIG-style record checks • Test ICMP ping and TCP latency • Check TCP ports and UDP diagnostic responses • Probe HTTP and HTTPS endpoints • Inspect SSL/TLS certificate details • Detect your public IP address • Scan your own LAN with ping sweep or selected TCP ports • Measure download and upload speed • Save local diagnostic history and export reports NetPulse is useful when a website does not open, a DNS record looks wrong, a VPN route changes, a certificate needs verification, a local device disappears from the network, or a service port does not respond. Built for both technical and everyday use: Developers can quickly validate hosts, ports, DNS records, SSL certificates and HTTP responses. Site owners can check whether their domain, website and certificate are reachable. Home users can inspect their current network, VPN state, public IP and local devices in a simple interface. Responsible diagnostics: LAN scanning is designed for networks you own or have permission to test. iOS may ask for Local Network permission before local device checks. Some routers, VPNs and cellular networks block ICMP ping, so NetPulse also provides TCP and HTTP checks as practical alternatives. Privacy-first workflow: No account is required. Reports are stored locally on your device. Diagnostic requests are started by the user when running a selected check, scan or speed test.

Your internet is slow. But why? Is the problem your Wi-Fi, router, ISP, DNS, or internet speed? NHCheck Lite finds the problem in about 30 seconds. FIVE SIMPLE CHECKS 1. Link Shows how this iPhone is connected: the network's name, its signal, the security in use, and your addresses. 2. Router Tests the connection to your router for: • Latency • Packet loss • Jitter It also finds devices on your local network, and names the ones that say who they are. 3. ISP Checks the first public router beyond your home router. This helps tell whether the problem is inside your home or with your internet provider. Tap the ISP result to trace the route to Cloudflare, Google, Quad9 or OpenDNS and measure every hop along it, so you can see where the delay is added. 4. DNS Tests how quickly your network can find website addresses. DNS can be slow even when your internet connection looks fine. Tap the DNS result to compare your resolver against Cloudflare, Google, Quad9 and OpenDNS. Each one is timed the same way, so you can see whether a faster resolver is available — and switch if it is. 5. Speed Measures real download and upload speed using real network traffic. Tap the Speed result to compare real downloads from Cloudflare, Google, Fastly, Akamai and Amazon — one connection, then four at once — so a line that is slow to one network can be told from one that is slow everywhere, and see which of them serves each part of X, TikTok, Snapchat or YouTube. No estimates. No simulated results. LINE TESTS AND TWO-PHONE SPEED On the ISP page, one tap runs a minute of pings that tells Wi-Fi drops from line drops, and finds the largest packet your connection carries. A chip beside the language switch measures Wi-Fi speed between two phones with no internet in it. The speed test also shows how much latency rises when the line is busy, and measures the result against the plan you pay for. KNOW WHAT TO FIX NHCheck Lite uses the test results to give you a clear recommendation. For example: • High router latency → check your local network • Packet loss past your router → contact your provider • Slow DNS → switch to a faster resolver If everything looks good: Nothing to fix. SEE THE PROBLEM NHCheck shows your connection as a simple path: Device → Router → ISP → Internet This makes it easy to see where the problem starts. SEE YOUR NETWORK Scan your local network to see which devices respond, and what each one calls itself. SHARE YOUR RESULTS Share the complete test result as an image with your ISP, technician, or anyone helping you. SIX LANGUAGES, DARK OR LIGHT English, Arabic, Spanish, Urdu, Portuguese and French, switched from the top bar. Arabic and Urdu are fully displayed right-to-left, including the connection diagram. Dark, light, or whatever your iPhone is set to. PRIVATE BY DESIGN No account. No tracking. No ads. No third-party SDKs. There is no backend server, and your app activity is not sent anywhere. The only network traffic is the traffic needed to perform the tests. LOCATION PERMISSION iOS requires location permission before any app can read the name of the Wi-Fi network you are on. NHCheck uses this permission only for that. NHCheck does not use GPS or track your location. You can still run every test without location permission. DATA USAGE The speed test uses real data. If you are on a metered or mobile connection, keep this in mind before running the speed test. Find the problem. Fix the right thing.
