Suli NetChecker

Suli NetChecker turns your iPhone or iPad into a complete network diagnostics toolkit — built for home users, IT pros, and anyone who wants to know exactly what's happening on their Wi-Fi. No more guessing why your internet feels slow or your router looks suspicious. Run real tests, get real numbers, and fix real problems — right from your pocket. ASK SULI AI Just tell Suli AI what you need — "run a speed test," "scan for devices," "trace route to google.com" — and watch it execute the tool live, right in chat. Ask for past results anytime with a simple "results" or "port scan results." CORE TOOLS - Speed Test — Real-time download/upload throughput with a live graph, ping, and your choice of test server (Cloudflare, Hetzner, Linode) - Ping Test — Min/avg/max latency to any host, with packet loss tracking - Port Scanner — Scan any device for open ports (FTP, SSH, DNS, and more) with live progress - Scan For Devices / LAN Scanner — Discover every device on your subnet, with manufacturer and IP details - Trace Route — Visualize the hop-by-hop path your traffic takes to any destination - IP Scan & Public IP Lookup — Check your local and public IP address instantly - Wi-Fi Integrated Test — One tap runs security, ping, web connectivity, and speed checks together, then grades your connection Excellent to Poor - Network Latency — Live ping to major internet services and your Gateway, refreshed automatically - Gateway & Device Details — Manufacturer, IP, ping, packet loss, and open ports for any device on your network - PoE & Bandwidth Calculators — Quick reference tools for network planning - Test History — Every result saved and searchable, so you can track your connection over time WHY SULI NETCHECKER - Clean, modern interface built entirely in SwiftUI — fast, native, and easy on the eyes - Real diagnostics, not guesswork — every number comes from a live test against your actual network - Works on both iPhone and iPad - No account required to use any tool PRIVACY Suli NetChecker only asks for the permissions each tool needs — local network access for scanning, and location access solely to detect your Wi-Fi network name (a requirement of iOS, not something we use for tracking). Test results are stored on your device. We do not track you across apps or websites. Whether you're troubleshooting a dropped connection, auditing your home network's security, or just curious what's connected to your router, Suli NetChecker gives you the tools to find out — instantly.
