iPerfBox
iperf2/iperf3 throughput test
£2.99
iperf2 and iperf3 built in. Run TCP/UDP throughput tests against your own iperf server right from iPhone or iPad and watch the live output — no extra tools needed.
iPerfBox is a lightweight network throughput tester that embeds the standard open-source iperf2 and iperf3 engines directly into the app and runs them in-process — no command-line tools to install on your device.
Features:
• Both iperf2 and iperf3 built in, switch with one tap
• TCP and UDP, with an optional target bandwidth for UDP
• Set server address, port and test duration
• Forward / reverse test (measure uplink or downlink)
• Custom-arguments mode: type a full iperf command line for advanced use
• Live iperf output log with selectable text
Great for verifying LAN bandwidth, troubleshooting Wi-Fi coverage, testing routers and NAS throughput, and field network diagnostics.
Requirements: you need a reachable iperf server (run iperf3 -s on any computer). This app is a client, collects no personal data, and connects only to the server you specify.
