Mandelbrot Maps

About this app

For each point in the famous Mandelbrot set fractal, there is a unique Julia set fractal parametrised by that point. Mandelbrot Maps is a fractal viewer designed to demonstrate the relationship between the two by generating the relevant Julia fractal in real-time as you move a pin across the Mandelbrot set.

Move around the fractals by dragging with one finger and pinch with two to zoom in and out. Hold your finger down to drop a pin and explore the Julia set. If you find a particularly beautiful spot, you can save the image or share it with friends.

Mandelbrot Maps is open-source software - you can find the source on my GitHub account, which is linked on this page as the developer website.

If you enjoyed using this version of Mandelbrot Maps, you might want to try Fractal Maps by Sky Welch, an updated version with improved speed and a side-by-side view - https://play.google.com/store/apps/details?id=io.bunnies.fractalmaps.

Chris King has also produced a version (not currently on the Play Store) that adds several more kinds of fractal - http://www.dhushara.com/DarkHeart/MM/MandelbrotMaps.htm.

This Android port of Mandelbrot Maps is based on the original web app created by Iain Parris (http://homepages.inf.ed.ac.uk/wadler/mandelbrot-maps/mmaps.html, http://www.inf.ed.ac.uk/publications/thesis/online/IM080583.pdf) and further developed by Edward Mallia (http://edwardmallia.com/mandelbrotmaps/), and Taige Liu. All versions were done under the supervision of Philip Wadler (http://homepages.inf.ed.ac.uk/wadler/) at the University of Edinburgh.

Ratings and reviews

This is probably the fastest Mandelbrot fractal zoomer on the web. The zoom function is much easier to use compared to the other fractal explorers. I also like how easy it is to switch to the Julia set. Plus it's open source and ad-free. There are a few things that could improve it, however. When I try to swipe around to move the view, the Julia pin appears and is distracting. Maybe disable the julia pin from appearing while moving the view. A way to view the coordinates of the julia pin would also be nice.

Worst one yet. Its render speed is fast. BUT, you can only zoom so far and it stops very quickly

This app is terrible it keeps closing down so I'm not able to use it. Its horrible!

What's new

Brought up to date with Android 4, fixed a crash in the Julia fractal view and ported the project to the Gradle build system.
