Fractals by Girino FOSS Explore the Mandelbrot set and related fractals directly on your Android device. Pan, pinch, and double-tap to navigate; long-press to read complex coordinates. A bottom bar offers zoom, reset, export, and a menu for 12 formulas (Mandelbrot, Burning Ship, Tricorn, Julia, Phoenix, and more) and 12 palettes with preview swatches. Toggle smooth coloring, set fixed / zoom-scaled / adaptive iteration limits, and edit Julia or Phoenix parameters. Your last viewport and choices are restored when you reopen the app. Rendering is progressive and entirely on-device. The fractal draws edge-to-edge under the system bars. The app contains no ads, trackers, analytics, network access, or data collection.
