iPerfman vs KFEI CSViewer

iPerfman measures network performance between your device and a compatible iperf3 server. Run TCP or UDP tests on iPhone, iPad and Mac. The free version allows three tests per day; Pro unlocks unlimited tests and advanced controls. Measure and investigate: - Test upload, download or both directions, with separate results for each direction. - Follow throughput in live charts. View UDP jitter and packet loss, TCP retransmissions, and round-trip time when those measurements are available. - Save completed tests with their configuration and interval results, then rerun a test or review its history. - Choose an IPv4/IPv6 interface when running a server, or listen on all interfaces. Unlock Pro with a monthly or yearly subscription, or a one-time Lifetime purchase. Pro adds unlimited daily tests, advanced iperf3 parameters, comparison of saved results, and full report export. The yearly subscription includes a seven-day free trial for eligible customers. Existing Lifetime purchases remain valid. iPerfman uses iperf3 3.21 through IperfSwift. A compatible server or second device is required for a network test; this is not an internet speed-test service. The Apple TV app uses a separate interface and has a different feature set.
