iPerfman2.0.1 - App Store

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.

Version History Version 2.0.1 fixes an issue that could make the app quit immediately after opening on iOS and iPadOS 15 to 18 and on macOS 12 to 15. Nothing else has changed since 2.0. 2.0.1 1d ago Version 2.0 saves completed tests so you can rerun a configuration, compare results, and review throughput, jitter, loss, and round-trip time over time. Comparison and full report export are Pro features in iPerfman.

TCP and UDP tests can now run in both directions, with separate results for upload and download. New DSCP/QoS controls and IPv4/IPv6 server-binding options give you more control over your tests.

The iPhone, iPad, and Mac interfaces have been refreshed, and live results are more responsive. Pro is now available as monthly or yearly subscription alongside the existing Lifetime purchase; the yearly plan includes a seven-day trial for eligible customers.
