GPU Mandelbrot
This app pushes the GPU to the limit by doing all the calculations in GLSL shaders and should be much faster than CPU based methods. At large zoom levels the shader code emulates double precision in a vertex shader and manages on most low end devices to get at least 43 bit precision instead of the normal 10 bit.
Try all the different options. Use two fingers or double tap to zoom. By holding a finger on the screen you can pan and zoom for as long as you like. The fractal will be updated when you stop touching the screen.
Turn off the automatic shader picker and manually try the different modes. The GLSL code is based on www.thasler.org/blog/?p=93 and uses some unusual constructs that some graphics drivers might treat differently.

it just crashes when you zoom
Works brilliantly - up to a point. This is the fastest Mandelbrot generation I've ever seen, BUT after I zoomed in and agreed to use emulated double precision it slowed the whole device to absolute slug speed. If this could be overcome and it could keep up its speed into deep zooms then it would be far and away the fastest and best Mandelbrot generator. It's just not quite there yet.
Crashes, locks, streaks. Nice concept but useless. Samsung S5
Crashes on my s4mini when more than ~70 iterarions. Please update!
This is so fast and fluid, one can explore the fractal world and see its beauty. The slow rendering of several others I have tried spoil the experience a bit. Would like to find one as good for other fractal sets.
Fantastically fast and really easy to use. But once you hit emulated double precision it just hangs.
Was cool
Hangs when zooming on both of my devices. Good idea - bad implementation.
Fast rendering, dodgy UI. The speed of the renders is a revelation, but the UI is so translucent that much of it is not readable at all. If the developer redid it with a more opaque background it would be superb.
