iPerf Falcon vs Throughput

iPerf Falcon brings native iPerf testing to iPhone, iPad, and Mac. Measure Wi-Fi, LAN, routers, NAS devices, servers, or broadband to find network bottlenecks. Connect to your chosen endpoint, listen locally, or automate the test over SSH. You control the target and method. Three ways to get started Connect • Enter any iPerf host and port, or choose from 8 free public servers • Check port reachability with one tap; Falcon Pro can also save and pin frequent targets Listen • Turn your iPhone, iPad, or Mac into an iPerf server • Listen on all interfaces or choose an IPv4 address from Wi-Fi, Ethernet, cellular, or VPN • See exactly which address and port the other device should use • Start once and accept multiple client connections until you stop listening; results follow your automatic or manual saving preference SSH (Falcon Pro) • Connect to OpenWrt, Linux, or another SSH device; start the iPerf server, run the test, and clean up automatically • Authenticate with a password, an OpenSSH private key, or no credential on a lab device configured to allow it • Run the server remotely, or listen locally and have the SSH endpoint connect back Professional measurement without the friction • Both iPerf3 and iPerf2 engines, switchable in one place • TCP and UDP with upload and download modes; iPerf3 also supports simultaneous bidirectional tests • A graphical form for direction, protocol, duration, parallel streams, bitrate, and more • Chart-focused results with clear live and average speeds, minimums and peaks, test stages, and elapsed measurement time • Throughput charts label direction, time, and units, follow your bits/s or bytes/s preference, and let you tap to inspect each sample • Open current test details during or after a run to see the connection and full configuration • Separate upload and download speeds, charts, and metrics for bidirectional tests • Live Ping, TCP RTT, retransmissions, UDP jitter, and packet loss • Text details for each measurement interval, plus a searchable parameter and command reference Keep the results that matter • Save every run automatically, or keep only the tests you choose • Add notes, search instantly, and load a saved configuration for your next test • History details share the test screen's readings and layouts, with direction, measured time, averages, extrema, protocol metrics, charts, interval text, and saved parameters and commands • Export individual results as CSV or JSON, or create a shareable result card Falcon Pro One purchase unlocks these features on iPhone, iPad, and Mac: • SSH remote orchestration • Advanced graphical options and iPerf command-line configuration—paste a command to parse and synchronize the graphical form, then save complete commands for quick reuse • Five built-in scenarios for VoIP, 4K streaming, gaming, NAS backup, and Wi-Fi roaming, plus custom presets • Saved targets and SSH endpoints • Charts and metric comparisons for up to 6 runs, plus batch history export Designed for Apple devices On iPhone, landscape keeps readings and run controls visible while charts and details scroll independently. Wide iPad and Mac windows show parameters and results together. On iPhone Duo, layouts adapt to both displays and place content on either side of the fold when space allows, preserving your page, drafts, and current test state. Larger text, light and dark appearances, and nine languages are supported: Simplified Chinese, Traditional Chinese, English, Japanese, Korean, German, French, Spanish, and Russian. On iOS 27 and macOS 27, App Shortcuts can open Speed Test, History, or Settings, or load a saved preset. Privacy first No account is required, and there are no ads or analytics trackers. Test history stays on your device. SSH passwords and private keys are stored only in the system Keychain. Test traffic goes only to the target you choose; the target list briefly checks port reachability.

Test network throughput between your device and an iPerf3 server. View upload and download speeds with smooth gauges and live charts, including average speed and a sustained one-second peak. FREE CLIENT FEATURES • Upload, download, or both in sequence • TCP and UDP, configurable duration, parallel streams, port, and UDP bitrate • Local server discovery with hostnames when available • Public server browser on iPhone, iPad, Mac, and Apple TV, with cached listings from iperf3serverlist.net and port-range retry options • Continuous testing with a 10-second pause between runs • Background client testing on iPhone and iPad while iOS allows execution • Live Activity with speed, direction, progress, and a chart • Apple TV remote controls and a layout designed for the TV • Native Mac app with a live menu bar gauge SERVER & HISTORY — OPTIONAL ONE-TIME PURCHASE Unlock server mode and saved history on iPhone, iPad, Mac, and Apple TV, plus saved history on Apple Watch, using the same Apple Account. • Run an iPerf3 server from the Server tab on iPhone, iPad, Mac, or Apple TV • See incoming test gauges and charts, and review completed server results during the current app session • Save completed client tests, inspect charts and results, and reuse test settings • Export saved results as JSON on iPhone and iPad GETTING STARTED Run iperf3 -s on another computer, then enter its hostname or IP address in the app. Compatible local servers can also be discovered automatically, or choose Configure > Public servers to browse internet servers. Public server availability varies. An iPerf3 server is required for native client tests; iperf2 and authenticated servers are not supported. UDP measures delivery at your chosen target bitrate. Each direction begins with a one-second warm-up before measurements appear. Server mode runs while the Server tab is open. iPhone, iPad, and Apple TV servers require the foreground; the Mac server can keep running while hidden. Background client execution is controlled by iOS and can be stopped by the system. Apple TV client tests require the app to remain in the foreground. APPLE WATCH Run HTTP upload and download tests against this app’s enhanced server mode, with charts, queue positions, latency, and optional saved history. Open the iPhone app to share discovered servers or its own running server. Tap a server on Watch to run a 15-second upload and download test with four connections. Both gauges and charts fit on one screen. watchOS may route traffic through the paired iPhone; results may not represent a direct Watch Wi-Fi connection. HTTP measures TCP payload throughput and does not measure UDP loss or UDP jitter. Keep the Watch app open during tests. No app account, advertising, or analytics. Test traffic goes directly to your selected server. History stays on each device and does not sync; Apple TV may purge cached charts. Purchases are handled by Apple.
