UDP TCP Sender & Receiver

About

UDP TCP Sender & Receiver puts essential network tools in your pocket. Send and receive UDP and TCP traffic, run ping tests, and see everything in clear, filterable logs—ideal for developers, admins, and anyone debugging or testing network connectivity. ► UDP • Listen on a port and receive UDP packets; your local IP is shown so others can send to you. • Send UDP messages to any IPv4 address and port. • Logs show every packet sent and received with timestamps. ► TCP Client • Connect to any host and port. • Send and receive text or hex; switch to hex mode for binary or raw data. • See connection status and all traffic in the log. ► TCP Server • Start a TCP server on a chosen port; the app shows your local IP for easy connection. • Accept multiple clients; send (broadcast) messages to all connected clients or work with individual connections. • Send and receive in text or hex with the same log view. ► Ping • Ping any host (domain or IP) to check reachability and latency. • Set the number of pings (1–100) and see results with round-trip times. ► General • Dark and light theme. • Filter logs (e.g. sent vs received) where available. • Clear logs anytime. Portrait-oriented layout for comfortable one-handed use. Built for quick network checks, prototyping, and debugging—no account required. Free to use, with ads to support development.
