iPerf Falcon

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.
