User Reviews

Users praise the app for a powerful CLI, granular argument control, iOS server mode, and support for custom commands, along with cross-platform iperf3 testing. However, many reviews report crashes, instability, and connection failures that undermine reliability. Some also note version compatibility issues that prompt upgrades. Overall, the app is strong for advanced testing but inconsistent in practice.

Pros

Full command-line interface provides detailed iperf results beyond simple summaries.
Granular control over iperf command arguments for precise testing.
Supports iOS server mode, allowing the device to act as an iperf server.
Allows adding custom commands/arguments for advanced usage and flexibility.
Works with iperf3 servers/clients across Linux, macOS, and other platforms for cross-platform testing.

Cons

Frequent crashes and overall stability issues (crashes on launch or during use).
Unreliable operation with common connection failures or invalid parameter errors.
IPERF version compatibility issues that require upgrading or cause version-related problems.

Recent reviews

please upgrade to iperf 3.11 and add more option features.

This iperf app stands out as it has a full command line interface so you can get all iperf details. Most other apps I’ve seen only show summary info

This is superior to other iPerf 3 tools because this gives a granular control of iPerf command arguments I.e. for those who wants to do various/more precise testing. I also like the fact this tool allows iOS device to be server mode. One suggestion/feature request I have is to make a one option/UI change such that for those who likes to do just quick most basic upload or download test with # of parallel streams, have easy user selectable interface. This way the app covers the need of basic user and also advanced users.
