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