iPerf Reloaded vs iperf3

iPerf Reloaded brings the power of iPerf3 — the industry-standard network performance tool — directly to your iPhone and iPad. WHAT IS IPERF? iPerf3 is an open-source tool used by network engineers, IT admins, and enthusiasts worldwide to measure real TCP throughput between two devices. Unlike internet speed tests that hit a remote server, iPerf tests your LOCAL network — Wi-Fi, Ethernet, VPN tunnels, or any IP connection — giving you accurate, raw numbers without server-side bottlenecks. WHAT YOU CAN DO • Measure download and upload throughput to any iPerf3 server on your network • TCP and UDP protocol support • Test with 1–10 parallel streams to saturate high-speed links • Choose test durations: 5 s, 30 s, or unlimited • Watch throughput evolve live in a smooth 5Hz real-time chart • Share test results as an image or CSV export • Optimized iPad landscape layout • Save and compare past test runs in the built-in history • Reusable test profiles for recurring measurements • UDP diagnostics with packet loss, jitter, and out-of-order packets • Search, filter, and directly repeat saved tests • Light and dark theme TYPICAL USE CASES • Verify your Wi-Fi access point's real-world speed • Diagnose bottlenecks in home or office networks • Benchmark a new router, switch, or network adapter • Validate QoS or VPN performance REQUIREMENTS An iPerf3 server must be reachable on your network. Run `iperf3 -s` on any Mac, Linux, Windows, or Raspberry Pi to start one instantly. Public iPerf3 servers are also available online (see iperf3serverlist.net). PRIVACY No tracking, no analytics, no ads. All test data stays on your device. No account required. iPerf Reloaded is a clean, modern SwiftUI rewrite based on the open-source iperf3 library.

iperf3 Mobile is a professional LAN throughput tool for home labs and power users. It embeds open-source iperf3 so you can run real, wire-compatible client and server tests across your local network, not a consumer internet speed test. ONE APP, CLIENT AND SERVER • Run as a client against any stock iperf3 server (Mac, Linux, NAS, or another device) • Run as a foreground server so phones, tablets, Macs, or Apple TV can be the other end of the path • One active test at a time, matching classic iperf3 behavior TEST THE WAY YOU ALREADY DO • TCP and UDP • Upload, download (reverse), multi-stream, and bidirectional • Live throughput chart plus UDP loss and jitter where applicable • Duration presets, stream count, and UDP target bitrate • Default port 5201, the same default as stock iperf3 FIND OTHER DEVICES • Bonjour discovery for other iperf3 Mobile servers on your LAN • Always enter a hostname or IP for stock iperf3 (-s) peers SHORTCUTS AND AUTOMATION • Run client tests from the Shortcuts app with host, port, duration, streams, protocol, and more • Start or stop the in-app server from Shortcuts (server keeps the app foreground while listening) • Structured results return throughput for multi-step automations and Siri BUILT FOR APPLE PLATFORMS • Universal purchase for iPhone, iPad, Mac, and Apple TV • tvOS UI sized for the living-room endpoint • Mac as a convenient always-reachable lab peer while the app is open PROPER TOOLING • Embeds upstream iperf3 (esnet/iperf); open-source license included in the app • Local Network access is used only for tests and peer discovery Need a quick start? Start the server on one device (or run stock iperf3 -s on a Mac/NAS), then point the client at that host and port.
