Galaxy
The planets, the brightest stars and the Moon, rendered from real imagery on the GPU.
Planets, Stars and Moon tabs. The planets are real 4K texture maps turned into spinning globes by a shader, and the Moon is lit from the true angle of the Sun for any date.
- Platforms
- Android 10+
- Version
- 2.0.0

What it does
- The eight planets as globes you can spin; Earth has moving clouds, city lights at night and an atmosphere
- Saturn's rings carry the planet's shadow
- Constellations that draw themselves and the 17 brightest stars compared
- Moon phases, a 29.5-day dial and rise and set times
How it’s built
- Per-pixel sphere rendering in an AGSL shader, with a lighter fallback for Android 10–12
- Small textures load first and 4K ones in the background; 9.9 MB APK, down from 16 MB in Flutter
