iPerf3 Client & Server

About this app

iPerf3 Client & Server brings the popular iperf3 network testing tool to Android.

Note: This is not a one-tap ISP speed test. iPerf3 measures throughput between two endpoints, so you need an iperf3 server (or a second device running Server mode) reachable on your network.

Use it to measure real-world throughput of your Wi-Fi, cellular, VPN, or wired (Ethernet) connections. Quickly see how your router, access points, or remote servers perform and identify bottlenecks in your setup.

Run iperf3 in Client or Server mode: your device can either initiate a test or act as a remote endpoint in the field, lab, or data center. It’s ideal for checking new equipment, validating network changes, troubleshooting performance issues, and verifying link quality.

Features:
• Run iperf3 tests as a client or as a server
• TCP and UDP testing
• Configure target host, port, duration, parallel streams, reverse mode, and more
• View detailed results for each test
• Works over Wi-Fi, cellular, VPN, and wired connections
• Clean, Android-optimized UI
