    Hello, some time back I published an app called Fractview (now FractViewLite), and I implemented it from scratch under the old name Fractview: https://play.google.com/store/apps/details?id=at.searles.fractview

    It is not an update but an entirely new application to replace the old one.

    Fractview is a highly customizable and userfriendly viewer for fractals in the complex plane. You can get an impression of the features in the following screen cast:

    The app's core features are
    • Moving/Scaling/Rotating/Shearing using very intuitive touch gestures (similar to Google Maps)
    • Immediate preview of the new fractal
    • Arbitrary formulas. In fact, everything that can be calculated can be drawn. There are some presets, from Mandelbrot Set, Newton fractals, Lyapunov fractals, Magnetic Pendulum simulation, Orbit traps, and so on...
    • Presets can be customized though an intuitive preference's menu. This includes a Julia-set mode implemented in most presets.
    • It uses the LAB-Colorspace for a very natural gradient of colors and support of 2D color palettes
    • All calculations are done in a virtual machine implemented in Renderscript, Google's back-end for intense calculations. Thus, even though the calculations are interpreted and not hardcoded, it is still very fast, factor 10 compared to FractViewLite.
    • Images can of course be saved and shared and you can freely pick the resolution
    • A text representation of a fractal can also be copied and shared so that others can import your images and further edit them in the app. You can find examples on https://plus.google.com/104944145222836108707 and instructions how to copy/paste these text representations in further screencasts https://www.youtube.com/channel/UCvl2XV_WsfwHLpr0NSDtNcg
    • Ah, and of course, app free, open source (GPLv3), because beauty of mathematics is priceless ;)
    I would be very happy on your input and suggestions on my app and hope you enjoy it. I attached two screenshots, one of the app in action and one of the color picker I implemented for this app.
