Network Simulator - Lag Test のアプリ分析 7月22日

Simulate real-world network conditions directly on your Android device. Perform on-device network simulation on real Android phones — no emulator, no PC, no external proxies. Test lag, packet loss, and bandwidth limits without root or system modification. Network Simulator is a professional network testing tool for developers and QA engineers, designed for real-device testing under poor or unstable networks. 🚀 Key Features 🌐 Network Condition Simulation • Simulate latency, jitter, packet loss, and bandwidth limits • Reproduce 2G, 3G, 4G, slow Wi-Fi, and custom weak network scenarios • Works with TCP, UDP, and ICMP (Ping) 📡 Packet Capture (PCAP) • Capture live network traffic during weak network testing • Export standard PCAP files • Analyze traffic in Wireshark and other tools • Inspect packet drops, latency, and protocol behavior 📊 Network Test Reports • Automatically generate network testing reports during simulation • View statistics on-device in CSV or interactive HTML format • Visualize upload/download latency and packet loss trends • Export reports for sharing, debugging, or documentation 🎯 Per-Domain Network Rules • Apply network conditions to specific domains or APIs • Whitelist or blacklist mode (mutually exclusive) • Simulate partial failures while keeping other services unaffected 🧑‍💻 Built for Developers & Testers • Floating control panel for real-time adjustments • One-tap presets for common weak network scenarios • Test real-device behavior beyond Android Emulator limitations • An Android alternative to iOS Network Link Conditioner 🔒 Privacy & Security • No root required • Built on Android VpnService for local traffic routing • All processing is done locally • No data is collected or uploaded Network Simulator helps you simulate poor networks, capture traffic, and analyze results — all on a real Android device.
