Description
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

Please revert it to how it was before. This update is not good; it's not working properly. Please change it back to the previous version. This update is not good; the previous one was better.

Dear Net sim Pro, the previous one was good, whenever you update the app, it does not work, you should do it as before, now if you update it, it does not work, so my request is that you should do it as before.
