Features & Capabilities

Explore the infinite beauty of fractals with your fingertips. Pinch to zoom, drag to pan, and dive into the endless detail of the Mandelbrot set and its relatives — rendered in real time on your device's GPU.

xFractal, first released in 2008, is back — rebuilt from the ground up for today's iPhone and iPad.

FEATURES: • Mandelbrot, Julia, Newton and Multibrot fractals • Deep zoom: magnify the Mandelbrot and Julia sets more than a trillion times • Four classic palettes — Hot, Cold, Gray and Chromatic — with smooth coloring • Julia presets (Dendrite, Spiral, Rabbit, Galaxy, San Marco), Multibrot exponents 2–8, three Newton polynomials • Replay: watch your whole exploration animate back as a short movie • Picks up exactly where you left off • Free and open source

Deep zoom uses K. I. Martin's perturbation technique.

User Reviews

Allows you to zoom in as deeply as a cheap 1950s toy microscope.

Portrait mode only on iPad, and performance is less than what I'd expect. Seems like it's using CPU calculation rather than any leveraging of the parallel capabilities of the GPU. Good quality rendering though.
