UDPup is a powerful yet elegantly simple utility for sending UDP packets from your iPhone or iPad. Build your own dashboard of custom‐labeled buttons—each with its own message payload and color scheme—and fire off network commands instantly. Whether you’re an IT pro testing network devices, a home-automation enthusiast triggering smart gadgets, or an MDM administrator provisioning dozens of devices, UDPup makes UDP communication effortless.

Key Features
• One-Tap UDP Sending
Configure your target IP address and port once, then tap any button to send its custom message payload.
• Custom Button Dashboard
Add, edit, or delete as many buttons as you like. Give each button a unique name, message, background color, and text color.
• Instant Visual Feedback
Buttons animate on press and disable for 3 seconds to prevent accidental repeats.
• Adaptive Layout
Grid layout automatically adjusts: two buttons per row in portrait, four in landscape.
• Persistent Settings
All host, port, and button configurations are saved between launches.
• MDM-Friendly Managed App Configuration
Preload host/port, buttons, colors, and even the app’s title via Jamf or other MDM solutions using simple key-value pairs.
• Dark & Light Mode Support
Seamless UI adapts to your system appearance.

Why UDPup?
• Speed & Simplicity: No complex scripting—just set it and tap.
• Enterprise-Ready: Supports MDM configuration for zero-touch deployment across hundreds of devices.
• Highly Customizable: Full control over button labels, messages, and colors.
• Universal: Designed for both iPhone and iPad, with a responsive grid interface.

Get up and running in seconds—configure your network target, create your custom command buttons, and start sending UDP packets with confidence. UDPup transforms your device into a dedicated UDP controller.
