umcode

umcode is a visual programming education app for kids that combines block coding, hardware control, and AI body interaction — helping children build computational thinking through hands-on making.

Key Features
• Block Coding: Write programs by dragging and snapping blocks — no prior coding experience needed. View the equivalent Python code instantly to bridge the gap between visual and text-based programming.
• Hardware Making: Connect an ESP32 microcontroller via Bluetooth (BLE) or USB to control motors, sensors, lights, and more — turning code into real, moving creations.
• AI Gesture Interaction: Use the camera to detect body poses and hand gestures, letting your program "see" movement. Build motion-controlled games and interactive projects.
• Guided Lessons: Follow built-in step-by-step courses and project tutorials. Scan the QR code in any instruction booklet to jump directly to the matching lesson.

Safe for Kids
• Fully offline — no internet connection required.
• No account registration or login needed.
• Zero data collection. All content stays on the device.
• No ads, no in-app social features. Designed entirely for children.

Who It's For
• Elementary and middle school students exploring coding for the first time
• School STEAM and maker club classrooms
• Families who want to learn programming together at home

Start with your first block — and build something amazing.
