The following fractal generators will run on mobile devices, such as smartphones and tablets, using Android OS. All of them are freeware, and can be obtained from the Google Play app store.

 

Fractal GeneratorFractal Generator ~ v1.2
OS: Android
author: Frosity
url: https://play.google.com
With a simple name as the one this app has, I’m sure it’s pretty easy to guess what it does. Yet, it comes with some really nice features that let you play with the pictures like few Android generators do. It only renders Mandelbrot, Julia and Newton fractals, shining at the second one, because it offers several parameters you can tweak by adjusting some sliders (I wish you could input the numbers directly, for better precision). The coloring tools are nice too: though it only has a few options (including some preset palettes), it allows for customization. If you use the SAVE icon to save your pictures, they are sent to an internal gallery (called “My Gallery”) that you access from the little Mandelbrot icon. To store them to your device’s Gallery, use the “Save image” command (under the three dots) instead. You can also share them directly to the Internet.

FractaldrawFractaldraw ~ v3.0
OS: Android
author: Florian Jasch
url: https://play.google.com
Fractaldraw is a nice app to explore fractal pictures. Its forte is exploring the Julia set using the presets that come by default as a starting point (find them in the first icon –the four little squares), but you can also start from scratch, and begin exploring the presets themselves. To modify the figure, activate a fixed point in the plane using the paintbrush (you can place more or delete some using the + and – symbols) and move the crosshair to change the structure. When done, deactivate the brush to start zooming by pinching and dragging. Use the volume control to rotate colors. The program will save images as PNG files, but won’t save parameters.

JWILDFIREfreeJWildfireMini FREE ~ v1.6
OS: Android
author: Andreas Maschke

JWildfireMini FREE is a stripped-down version of JWildfire for Android. As its more powerful desktop sibling, the Mini can render batches of random flame fractals that you can save for later mutation (that is, generating secondary sets of images based on the first one). Unfortunately you can’t do anything else since exporting of images or parameter files is disabled in the free version. To enable export function you’ll need to get the paid version (for less than US $3.00, it won’t certainly drain your bank account). In other words, this compact gimmick it’s mostly fun on the go. It also comes with a Flame Gallery, storing 30 beautiful pictures for your enjoyment. If you get the paid version, you can export the parameter files and then import them to the desktop application for better controls and lots of options to enhance your pictures.

MandelbrotMandelbrot ~ v1.7
OS: Android
author: Dmitry Brant (Defiant Technologies, LLC)

Mandelbrot is a nice and fast Mandelbrot and Julia sets explorer (it shows the corresponding Julia set for each point in the Mandelbrot set). It’s quite easy and intuitive to use: pinch to zoom in or out, press and drag to move, and that’s it. Volume control sets the iteration level, but you can also click the gear to open a slider that lets you do that too. Though it doesn’t have the artistic capabilities of a desktop application, it’s very efficient as an exploration tool, and the resulting images are quite attractive as pure fractals. It includes several coloring maps/algorithms, and will save Mandelbrot pictures (not the Julia, regretfully) as PNG files. Image size will depend on the device’s screen resolution.

Mandelbrot MapsMandelbrot Maps ~ v1.03
OS: Android
author: Alasdair Corbett
url: https://play.google.com
Mandelbrot Maps is a very simple app to explore the Mandelbrot set and its corresponding Julia set for every point selected, much like the Mandelbrot app from Dmitry Brant, but somewhat even more simpler. Just move the blue dot anywhere over the Mandelbrot image to see its Julia counterpart in the small box on the upper left corner. If you want to see a larger Julia image, simply click that small window and the images will switch places. That’s pretty much what this proggy does. Yep, that’s all. The only way to save pictures is doing screen captures.

mandelsplitMandelsplit ~ v0.1.12
OS: Android
author: Johannes Gajdosik
url: https://play.google.com
This is another simple Mandelbrot explorer with some control options. Basically, you pinch the screen to zoon in or out and move around as usual. If you  hold on the screen a small window will show up, which will let you modify the number of iterations, enable rotation of the figure and  swap between several RGB color palettes. The only way to save pictures is doing screen captures; parameters can’t be saved.
