About this app

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.

What’s new

Fixed motor direction handling and inconsistent direction icons in tutorials and the programming editor. Unified block labels and behavior across coding, tutorials, 3D program panels and help previews. Improved the number keypad layout on small landscape screens. Existing projects are preserved.
