Requires access to an iPerf3 server (local, VPN, or remote). This is not a general Internet speed test. iPerf3 Client & Server brings the standard iPerf3 tool to iPhone and iPad with a clean, native UI. One purchase also unlocks the Mac version. Measure real throughput across Wi-Fi, cellular, VPN, or LAN. Compare routers and access points, validate ISP or VPN changes, and find bottlenecks. Key features: - Client and server modes - TCP/UDP tests, including bidirectional and reverse - Advanced controls: duration, parallel streams, bandwidth caps, window size, MTU - Shortcuts automation + x-callback-url for power users - Saved server profiles and favorites - History with charts and CSV/JSON export - Detailed metrics: throughput, latency, jitter, packet loss Automate repeatable workflows with Apple Shortcuts or x-callback-url (run tests, fetch results, and chain actions). Built for network engineers, sysadmins, and power users who need accurate, repeatable results.
