Editor's review
Download the latest Fractals application, version 2.06, compatible with Windows 10/11 (using emulators such as Bluestacks), Android devices. This free Entertainment app is developed by JMorris and is easy to download and install.
Previous versions, including 2.06, are also available. If you need help or have any problems, please let us know.
Description
- Save it to your device as a PNG file and then use your favourite image editor app later to process the image further, print it or share it.
- Set your wallpaper (don't worry the current wallpaper image is saved so you can reverse the change).
It's that simple.
Other Features:
- Swap between the Mandelbrot and Julia sets , draw the burning ship or define your own custom fractal formula. Custom formulae support constants pi and e, +, -, *, /, and ^ and the functions abs, sin, cos, ln, exp, re, im and the standard fractal variables z and c.
- Define custom colour maps for Hue, Saturation and Value as a function of the number of iterations (x). Custom colour formulae allow the use of the mod (%) operator in addition to the functions supported by the custom fractal formula.
- Show the orbit for the current touch point.
- See the corresponding Julia Set for the given touch point on a Mandelbrot Set and switch to it via a double tap.
- Long press to show the coordinates for that point in Cartesian and polar form.
- Define a custom background colour as an R,G,B value. E.g. R=255,G=255,B=255 gives white.
- Define the magnitude value used for halting fractal iterations.
- If you get lost in your fractal exploring you can always reset the image via a menu option.
- The zoom factor and other settings such as the position of the centre of the screen are recorded in brief in the image file name and in full in the PNG "Description" tag so that you can always go back and recreate an image and tweak its colours or position.
- Fractal always remembers where you have got to when you close the app so you can always come back to it later.

5 ★ Great app for exploring fractals, really simple to use and loaded quickly on my phone (Oneplus One). Lots of options for customising fractals and an option to set fractals as your phone wallpaper, would definitely recommend this app.
5 ★ I have tried a few fractal apps and this is the best I have come across. The UI is really clean and I love the custom fractal option and the ability to customise the colours.
5 ★ Very easy to use. Great app.
5 ★ Really easy to use. I wanted an app that I could use to find some unusual fractal pictures and then set my wallpaper and I don't want ads getting in the way. This fits the bill perfectly. Loads of nice touches throughout: remembers where you were, easy to change all the colours and the files you save store the settings used so you can go back later and get back to where you were.
