Bouncy is a simple, joyful little app: fling a ball across your screen, and watch it bounce off the walls — playing a cheerful musical note each time it hits.
Every bounce produces a tone from the diatonic scale, so the ball essentially plays a little tune as it moves around. A visual effect (powered by Android's AGSL shader language) that changes by each wall hit.
That's the whole app. No levels, no score, no accounts — just a ball, some physics, and a bit of music.
Features:
- Fling the ball with a swipe and watch it go
- Each wall bounce plays a note from the diatonic musical scale
- Smooth, realistic physics using Android's FlingAnimation
- Visual glow effect rendered with AGSL distance field shaders
- Extremely lightweight: the entire app is under 18 KB
- No internet connection, no ads, no tracking, no permissions
