WeakSim is an iOS weak network simulator. It intercepts device traffic through the system VPN (Packet Tunnel), applying delays, packet loss, bandwidth throttling and other impairments to TCP/UDP packets locally. It reproduces real-world weak network scenarios such as subways, elevators, high-speed trains, and poor signal areas, helping you verify your app's timeout, reconnection, and degradation logic.
