Network Diagnostics App helps you see how your connection is really performing. Run a one-tap speed test for download, upload, latency, and jitter, plus a clear network quality readout—handy when home Wi-Fi stutters, the office network drops calls, or video meetings freeze. Keep results in history to compare times of day and different networks. Free features include basic speed tests plus Ping, traceroute, and DNS lookup so you can rule out common issues first. Pro is a one-time unlock: unlimited speed tests, speed history and shareable results, plus certificate checks, port scanning, LAN device scan, network diagnostics, Bufferbloat testing, signal monitoring, and more. Free users can complete up to three successful speed tests; then upgrade to Pro for unlimited testing and advanced tools. Pro is a one-time purchase for permanent unlock; price is shown in the App Store for your region. Use speed and diagnostic tools on a stable connection for best results.
