User Reviews

Fast Fractal offers real-time Mandelbrot and Julia rendering with smooth pinch-zoom and easy double-tap Julia view. It provides strong customization via advanced settings and retina-quality visuals, including tablet landscape support. However, reviews warn of drawbacks: a hard zoom cap, intrusive ads, memory issues on older devices with oversampling, and comparatively slower performance with fewer color options than some rivals. Overall, it's a capable mobile fractal explorer with impressive speed and UI, but notable trade-offs exist.

Pros

Fast real-time rendering with smooth pinch-zoom on Mandelbrot/Julia
Intuitive pinch-to-zoom and quick access to Julia sets via double-tap
Advanced settings for iterations, zoom, and oversampling enabling deeper detail
Beautiful visuals with vibrant colors and retina quality, plus tablet landscape support

Cons

Zoom is capped; hard limit prevents deep zoom
Intrusive ads/popups
Oversampling can cause memory crashes on older devices
Slower performance and fewer color options compared to some rivals

It’s fine I guess but you can barely zoom in at all!

I have always been curious about the Mandelbrot. I have had many apps that work good but don’t ever allow you to zoom by pinching. It projects a very clear image and allows you to zoom very far into the fractal. So this definitely deserves a 5 star rating.

I grew up programming fractals in the 80s on my Atari ST, took around half and hour per render what you can do on iPhone in real time. Thanks Tom (Kerrigan) for Programming this. Quick wish, if it so moved you to implement this: once at max zoom level, allow a button press to automatically “fly out” eg auto-zoom out. That be nice. Anyway. Really love it.
