## Description

This app is an iOS port for iperf3, which is the most commonly used network testing and performance computation tool. Iperf is a tool to measure maximum TCP bandwidth, allowing the tuning of various parameters and UDP characteristics.

Features
- Compatible with iperf3 in other platforms
- Run as iperf3 client or server
- Customize iperf3 arguments
- Display Wi-Fi interface link speed and SSID

IMPORTANT
This application is based on iperf 3.21, which is not compatible with the legacy iperf (version 1.x and 2.x). And it may have some minor issues with the other iperf3 versions.

## Review summary

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.
