Why Mandelbrot Metal

Mandelbrot Metal 3 is built for interactive precision and GPU-first deep rendering on iPhone & iPad, with the complete mathematical engine available in Free and optional Pro creative tools.

  • Infinity Engine: CPU double-double reference construction with Metal quad-single perturbation and recovery.
  • Mandelbrot + Julia modes with bookmarks that preserve the active fractal type.
  • Adaptive finite precision through a validated 1×10²⁵ product ceiling, with safe fallbacks.
  • Free/Pro model: all built-in palettes and the full renderer in Free; custom palettes, 3D Look, unlimited bookmarks, and high-resolution export in Pro.

6
Conservative by design for credibility. “Not stated” does not mean “not possible”—it means it wasn’t explicitly claimed in the sources used.

Scoring methodology

The score is a transparent summary of capability coverage, not a quality rating. Each capability column is scored:

  • ✅ Yes = 2 points (explicitly stated capability)
  • ◐ Partial = 1 point (implied/limited, or non-specific claim)
  • — Not stated = 0 points (not claimed publicly in the sources used)

Total score = sum across all capability columns. This approach is intentionally conservative to avoid over-claiming.
