Fast Fractal

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.

I overall love this app. I am amazed at how detailed and clear the images of the Mandelbrot set are. I also love how for each point on the Mandelbrot set, the corresponding Julia set can be accessed also simply by a double tap. However, I do have a suggestion for improvement, relating to zooming. Overall, the zooming feature is very convenient, except that sometimes I want to zoom far inside the Mandelbrot set to one specific spot, but then the zooming hits a “dead end”. I know that of course that no software can zoom truly indefinitely, but perhaps there can be a “maximum zoom” option in the settings, where one can set the maximum magnification factor by which one can zoom into the Mandelbrot or Julia sets. If the developer could add such an option to the settings, then that would make the exploration of these fractals even more interesting.

this is what I see when I rub my eyes too hard

Constant annoying ads and the core functionality of the app is laughable. You can only zoom in a small amount. Don’t waste your time.

Just pinch and zoom and explore in real-time. Amazing! One request , add a button to start where you are and slowly zoom back out. Extra points if you include a slider for speed. Add add bookmarks so you can zoom from start to book mark and back. Then charge a dollar! Lol great app!

The reviewers for the app who are saying you can only zoom in so far before the iterations stop forgot to look in the settings. You can control the number of iterations, the zoom and much more. It just slows down the rendering, as you'd expect. Also worth noting, for those of us with large tablets, the screenshots are misleading; the app DOES provide landscape view (aka widescreen).

Having written several Mandelbrot programs, I am blown away by the speed and responsiveness of this one. You can go deeper by increasing the iteration count on the Advanced menu.

You can zoom a few times and then it just hits a hard stop and refuses to zoom further or render additional detail. Fractal explorers are fun for hours when you can keep going and going and get into weird edge detail, and this app has neither of those things. It only offers a Mandelbrot set, which despite being my favorite is still only one of the many fun fractal explorations. It's no faster than Fractint was back in the 486 days despite the author's claims above. To add insult to injury it pops up an annoying ad every time you open it. This app was deleted within 2 minutes, as I'd seen all it had to offer, and it wasn't much.
