TcpButtons

Send TCP commands with a single tap. Fully customizable buttons — titles, messages, colors. Built-in local echo server to test without any hardware. Simple, fast.

TcpButtons turns your iPhone into a simple, reliable remote control for any device that listens for TCP messages. Whether you're controlling a home automation setup, a microcontroller project, a lighting rig, or your own custom server, TcpButtons lets you trigger actions instantly with no coding and no complicated setup.

Create buttons with your own titles, messages, and colors, and organize your controls exactly the way you want. Set your destination host and port, and messages are sent exactly as typed, in UTF-8, with no extra characters added. If you don't have hardware handy, enable the built-in local echo server to start a TCP server right on your device and test the full send and receive flow without any external equipment.

Every message sent and received is tracked in an activity log right on the main screen, so you always know what happened and when. A test mode is also available to preview button behavior and log messages without opening an actual network connection, which is useful for double-checking your setup before going live.

TcpButtons is built for makers, hobbyists, and developers who need a fast, no-frills way to send raw TCP messages to a server or device, whether you're testing a custom protocol, controlling an IoT project, or automating a workflow that speaks TCP. There are no accounts, no ads, and no unnecessary permissions. Just open the app, configure your buttons, and start sending.
