About this app

iperf3 Speed Test is a modern, easy-to-use graphical front end for iperf3 — the
industry-standard network performance tool — that runs a real iperf3 client right on your phone.

speedometer measure your throughput and latency in real time.

Features:
• Real iperf3 engine running natively on your device
• Live speedometer with download/upload speed and ping
• Download, Upload and Bidirectional tests over TCP or UDP
• Choose from a built-in list of public servers or add a custom one
• Basic and Advanced settings (duration, parallel streams, window size and more)
• Detailed results with throughput and latency graphs and total data transferred
• Your connection info: active network, local and public IP, country and provider
• Share a clean result image to your friends and social networks

No ads. No tracking. Just a fast, accurate way to test your connection.
