Quick answer

Explore Mandelbrot and related fractals offline

F-Droid repository metadata

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.

How to install

  1. Download the APK from the button at the top of this page.
  2. Allow “Install unknown apps” for your browser or file manager only, not for every app.
  3. Open the downloaded file and confirm the installation.
  4. If installation fails with “App not installed,” remove an earlier build of the same app first. A signature conflict is the usual cause.
