MyIPERF3: IPERF3 Client/Server

MyIPERF3 runs the real iperf3 on your phone, tablet or Android TV. Measure your Wi-Fi, mobile data or Ethernet against any iperf3 server, or turn the device itself into one. It's the same iperf3 3.22 you would run on a computer, with a live gauge, charts and a history of every result. No account, no ads, no tracking.

TEST YOUR NETWORK

• Download, upload, both at once, or download then upload like a speed test site

• TCP or UDP, any duration, parallel streams and a target bitrate

• A live speed gauge and throughput chart, with RTT, retransmits, jitter and loss

• Choose the network a test uses: Wi-Fi, mobile data or Ethernet

• Stop at any time and keep what was measured

EVERY IPERF3 OPTION

• Advanced options cover every iperf3 client option: warm-up, window and buffer sizes, MSS, congestion control, DSCP, IPv4 or IPv6, bind address, timeouts and more

• The exact iperf3 command is shown as you change them, ready to copy

BE THE SERVER

• Start an iperf3 server on this device and test against it from a computer, phone or TV

• It shows this device's addresses, the command to type and a QR code

• It keeps running in the background with a notification, and can start when the device starts: an always-on test server on a TV box

• Other copies of MyIPERF3 on your network find it by themselves

FIND SERVERS

• Save your servers with names, and pick recent ones again

• Scan your network for any iperf3 server, or paste a whole iperf3 command

KEEP EVERY RESULT

• History with charts, filters, search and your best download and upload

• Export to CSV or JSON, share as text, or see iperf3's own JSON output

MADE FOR EVERY SCREEN

• Phones, tablets with two panes side by side, and Android TV with a remote-friendly interface

• Light and dark themes, pure black for OLED screens, accent colors or Material You, and bits or bytes

• In English, Spanish, Portuguese, French, German, Russian, Dutch and Italian

PRIVATE BY DESIGN

• No accounts, no ads, no analytics, no tracking

• Tests talk only to the iperf3 servers you choose, never to us

REQUIREMENTS

• Android 8 or newer, on a phone, tablet or Android TV

• An iperf3 server to test against: another device running MyIPERF3, a computer running iperf3, or a public iperf3 server
