## What is Volume Shader?

Volume Shader is the viral Volume Shader BM GPU test, built natively for iPhone and iPad.

The Mandelbulb ray march runs in Metal on your iPhone or iPad.

WHAT YOU CAN DO
• Run Volume Shader BM at Simple, Standard, Advanced, or Extreme
• Use Standard + 30 seconds when you want a score you can compare
• Drag to rotate, pinch to zoom, and pan. Explore does not save a score.
• Time CPU and memory on the same device
• See GPU, memory, display, storage, and thermal state
• Walk a display, touch, haptics, speaker, and battery checkup

HEAT AND BATTERY
This is a real GPU workload. The device can get warm and the battery will drain faster while a test is running. Extreme asks for confirmation. The app stops itself if iOS reports a critical thermal state.

PRIVACY
No account. No ads. Tests, history, and checkup marks stay on this device. Nothing is uploaded. If you tap Share, iOS’s share sheet sends only what you chose to the app you pick.
