GaltonLab

Galton Lab is a Galton board simulation focused on the joy of watching balls fall and accumulate in real time.

Instead of showing results first, the app lets you experience the distribution as it forms. Balls bounce through the pegs, flow into the lower tubes, and gradually build up into a familiar bell-shaped pattern.

Features:
- Full-screen, immersive Galton board presentation
- Natural ball-by-ball drop and accumulation animation
- Tilt control using your phone's motion sensor
- Simple controls for stages, right probability, ball count, and speed
- Supports Japanese and English

Designed to feel like a hands-on science museum exhibit, Galton Lab is an app for experiencing probability, not just reading a chart.
