Mandelbrot Metal

About Mandelbrot Metal

Mandelbrot Metal is an independent software studio working at the intersection of art, mathematics, science, and high-performance graphics. Founded by engineer Michael Stebel, the studio creates precise, visually striking apps that harness the computing power and GPUs of modern Apple hardware. Mandelbrot Metal, the studio’s flagship app for iPhone and iPad, brings Mandelbrot, Julia, and other fractals to life. Version 3 introduces the Infinity Engine, combining Metal-accelerated perturbation, quad-single recovery, compensated coordinates, and adaptive precision for responsive exploration at magnifications up to 10²⁵. Browser-style Exploration History restores complete creative states, giving users the freedom to experiment and retrace their discoveries. Available with a free tier and optional Pro upgrade, the app has ranked among the top 10 on the US App Store’s Graphics & Design chart every week since launch. Learn more at Mandelbrot-Metal.com. PaletteWright™ for Mac and iPad is an accessibility-first color-system compiler for designers and developers. Its Source, Build, Roles, Validate, and Ship workflow connects color inspiration to implementation. Import colors from screens, photos, websites, CSS, tokens, folders, and palettes; refine them with perceptual models; map roles, aliases, and components across Light, Dark, and Increased Contrast modes; and preview interfaces. Validation evaluates declared relationships across modes and states using WCAG 2.2 contrast, versioned APCA guidance, color-vision analysis, local Figma audits, and rendered WebKit checks, with clear Pass, Fail, or Needs Review outcomes. Support for tagged sRGB and Display-P3, known-alpha compositing, ranked collision analysis, and lock-preserving repair candidates helps users assess and refine their systems. Adaptive exports support Web, Apple, and Android development. Learn more at PaletteWright.com. Both apps are available in 16 languages.
