Fractal Forge

Fractal Forge is a comprehensive mobile fractal explorer with 350+ GPU-accelerated fractal types for deep zoom, customization, and export.

350+ fractal types — the largest collection on any mobile app

Mandelbrot, Julia sets, Burning Ship, Tricorn, Celtic, Buffalo, Newton basins, Nova, Phoenix, Lyapunov, Buddhabrot and hundreds more —

spanning escape-time fractals, strange attractors, cellular automata, space-filling curves, tilings, root-finding methods, and 3D

ray-marched fractals (Mandelbulb, Mandelbox). All rendered in real time by GLSL fragment shaders on the GPU.

Deep zoom with multi-precision rendering

A three-tier precision engine provides float32 GPU rendering, double-float GPU emulation (up to 10^14x magnification), and CPU fallback

with full double-precision math.

60+ colour schemes with sRGB-correct science

Smooth colouring, orbit traps, normal-map bas-relief shading, distance estimation, stripe averaging, triangle inequality averaging, and

curvature averaging techniques.

Dual Mandelbrot / Julia viewer

See Mandelbrot and its corresponding Julia set side by side. Tap any point in the Mandelbrot half to instantly update the Julia seed.

Export and share your discoveries

Save any fractal as a high-resolution PNG with optional transparency and share directly from the app.

Auto-explore mode

Let the app discover interesting regions automatically with intelligent zoom navigation that finds beautiful structures in any fractal.

50+ built-in presets

Jump straight to famous regions — Seahorse Valley, Elephant Valley, deep spiral arms, Julia islands, and more.

Accessibility built in

WCAG AAA high-contrast theme, reduced-motion support, screen reader labels, and configurable touch targets.

No ads. No data collection. No tracking.

Your exploration stays on your device and remains entirely private.

Perfect for:

- Math and science learners exploring complex dynamics

- Digital artists seeking procedural and generative inspiration

- Educators creating visual demonstrations

- Researchers visualising mathematical structures

- Anyone who wants to see infinite beauty in mathematics
