Stack

Android, Kotlin, C (iperf3 native), JNI

Problem

Network engineers and developers needed a proper iperf3 client on Android — not a web wrapper or a simplified clone. The existing tools on the Play Store were outdated, missing server mode, or lacked the full iperf3 flag set.

Solution

A full-featured Android app wrapping iperf3 v3.16 as a native library via JNI. Three core modes expose the complete tool:

Client Mode — standard iperf3 client, TCP and UDP, with configurable parameters.
Server Mode — turns the phone into an iperf3 server on a user-defined port.
Advanced Mode — full manual control over all iperf3 flags, for power users.

Engineering Highlights

Native iperf3 v3.16: compiled for Android ABI targets and bridged with JNI. The app runs real iperf3, not a re-implementation.
Real-time charts: live RTT, bandwidth, and jitter graphs rendered during an active test.
Test history: persistent local storage of results with CSV and JSON export.
14 languages: full localization including Arabic and Hebrew (RTL support).
Theme system: light/dark mode + 10 color schemes with per-test color coding.
Cross-platform awareness: the same Google Play app ID is used for cross-promotion alongside the Apple version.

Platform Constraints

Android 7.0+ (API 24) covers the target audience of network professionals. The native binary is compiled for arm64-v8a and armeabi-v7a. Battery and wake lock handling ensures tests complete on locked devices.

Outcome

The most complete iperf3 implementation on the Android Play Store. Used by network engineers for LAN, Wi-Fi, and mobile broadband testing. Part of the iPerf3 product family alongside the Apple version.
