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)
