iPerf3 Lite (TCP/UDP)

iPerf3 Lite is a lightweight iPerf3 client for accurate TCP/UDP bandwidth testing over Wi-Fi, LAN, or cellular. Lite is client-only. You need an existing iPerf3 server (e.g., on a PC, router, NAS, or another device). This is not a one-tap “speedtest” app. It’s a real iPerf3 tool for troubleshooting networks, routers, and ISP issues. Lite features • iPerf3 client: TCP / UDP • Reverse mode, multiple streams, duration control • Detailed results + history • Adaptive UI for phone/tablet, dark theme • Optional lightweight ads (no interstitials) Pro version • Built-in iPerf3 server on the phone • Export results to CSV/JSON Typical uses – Validate Wi-Fi/LAN throughput and router/AP performance – Compare cellular vs Wi-Fi or different access points – Troubleshoot packet loss and stability (UDP)
