Measure your network bandwidth on Android
Measure network bandwidth with iPerf2 and iPerf3 on Android
Run iPerf2 and iPerf3 bandwidth tests on Android and measure throughput, packet loss, jitter, and other network performance metrics.
Features
iPerf2
Use iPerf2 on Android for network bandwidth and performance measurements, including multiple simultaneous connections.
iPerf3
Run iPerf3 tests directly on Android with support for modern TCP and UDP testing features.
TCP Testing
Measure TCP bandwidth and inspect MSS, MTU, socket buffer, and other network parameters.
UDP Testing
Generate UDP streams with a specified target bandwidth and measure packet loss and jitter.
SCTP Support
Run bandwidth measurements using SCTP over IPv4 and IPv6 networks.
Multiple Connections
Run multiple simultaneous connections to test network performance under higher traffic loads.
JSON Output
Use iPerf3 JSON output when integrating test results with scripts or other analysis tools.
Disk Testing
Perform supported iPerf3 disk read and write tests to evaluate storage-related performance.
About this app
iPerf for Android
iPerf is a network performance measurement tool ported to Android. It supports both iPerf2 and iPerf3 for actively measuring the maximum achievable bandwidth of IP networks.
Run bandwidth tests between Android devices and other supported platforms to evaluate network performance and troubleshoot connectivity issues.
Features
- iPerf3 and iPerf2 — Use both iPerf versions directly on Android.
- TCP bandwidth testing — Measure TCP network throughput and inspect related parameters.
- UDP bandwidth testing — Generate UDP streams with a specified target bandwidth.
- SCTP support — Perform bandwidth measurements using SCTP over IPv4 or IPv6.
- Packet loss measurement — Measure packet loss during UDP tests.
- Jitter measurement — Measure delay variation during UDP tests.
- Multicast support — Perform multicast network tests.
- MSS and MTU information — Report network parameters observed during tests.
- TCP window tuning — Support TCP window size through socket buffers.
- JSON output — Use iPerf3 JSON output for automated processing and analysis.
- Multiple connections — Run tests using multiple simultaneous connections.
- Periodic reports — Display intermediate bandwidth, jitter, and packet-loss measurements.
- Configurable test duration — Run tests for a specified period or amount of data.
- Disk testing — Perform disk read and write tests through supported iPerf3 options.
- IPv4 and IPv6 — Test IP networks using both address families.
iPerf versions
The app includes both iPerf2 and iPerf3 binaries.
For network bandwidth testing, iPerf2 can be useful when multiple simultaneous client connections are required.
The latest iPerf3 binary has been updated to 3.19.1.
Cross-platform testing
Use the Android app with iPerf installations on other supported platforms, including:
- Windows
- Linux
- Android
- macOS
- FreeBSD
- OpenBSD
- NetBSD
- VxWorks

Frequently asked questions
iPerf is a network performance measurement tool used to measure the maximum achievable bandwidth between network endpoints.
iPerf2 and iPerf3 are separate implementations with different features and behaviors. This app includes both versions so you can choose the appropriate tool for your network test.
Yes. You can use iPerf to measure network throughput between devices connected through Wi-Fi or another IP network.
iPerf primarily measures bandwidth between an iPerf client and server. It is most useful for testing the network path between two endpoints rather than measuring a typical Internet speed-test service.
Yes. UDP testing supports configurable bandwidth streams and can report packet loss and delay jitter.
Yes. Both iPerf2 and iPerf3 support TCP bandwidth testing.
Yes. iPerf supports network testing over IPv4 and IPv6.
Yes. The app can run iPerf server tests so another iPerf client can connect to the Android device.
Yes. The Android app can communicate with iPerf installations on Windows, Linux, macOS, and other supported platforms.
