Fractile Plus: Faster Fractals

Fractile Plus is a fast Fractal viewer which allows you to explore the famous Mandelbrot set. Even though the set is based on a very simple mathematical formula, it has amazing complexity. Zoom in to find intricate spirals, flaming tendrils, and an seemingly endless smaller repetitions of the set itself.

- Unique tile-caching design makes this the fastest fractal browser on the app store.
- Silky smooth 60FPS pan and zoom
- Julia set with real-time preview
- Save high-res images up to 13 megapixels
- Pinch-zoom in up to 10 trillion times magnification
- Set detail up to 4096 iterations
- Fully optimized for iPad and retina display
- Free!

What's New in Version 2.2

Choose from 15 different color palettes; dithering for smoother gradients.

Best fractal app I can find

This is the best fractal app I've found. I've tried many others, but none of them were even close to the quality of Fractile Plus (apps like iFractals). The only things I dislike are the loss of detail in some areas as you zoom in, the limited color choices, the limit to how far you can zoom in (about 14E12 times), and how it sometimes doesn't finish loading the image when you're zoomed in really it forgets to or something. And how it doesn't always load the Julia sets correctly (on some of them when you zoom in a little, parts of it turn into weird blotches of color...looks pretty, but it's a little annoying). Other than that, I love it. What I'd really love to see in future updates is a higher magnification capability, the option to customize the colors (in addition to the color templates it already has), greater detail, and the addition of other fractal graphs (namely, the "burning ship"). And, of course, the correction of the minor glitches. Over all, great app. Definitely worth getting.

About perfect for a mobile application

I will admit it, I think that having higher zoom capability would be epic. And yeah, maybe 4096 iterations isn't entirely enough for the current max zoom level. Yeah, the max iterations becomes slow at high zoom.

But this is a phone we're talking about here. How much can you really expect from your phone? If you want anything more, go turn on your computer. Your phone's not a freaking supercomputer, you can only ask so much from it. And why bother having your phone running over night when your computer would do a better job faster?

Now then, custom palettes and animating palettes are perfectly reasonable demands that I would love to see but are non critical. More fractals would be epic, but a lot more work for developers than other suggestions.

Saving pictures at standard sizes on the other hand, should be (relatively) easy to implement, and truly is just common sense. Fix this, please.

Exceptional free app

It is hard to believe this is free and no ads. I was a math geek in high school (late 70's) when fractal displays were just being developed. Over the years I have tried many of these programs, I have bought several here, and on the mac app store.

This app truly is very good, and is worth a payment. If the developer had a pro version (I.e. One with better color options, user selectable iterations, manual point entries etc) I would buy it.

I have created numerous beautiful screen savers from this app, downloaded on my friends iPads and done the same for them.

Exploring an infinite complex number formula via graphics is a great time waster, but really, the images you can find with this app are wonderful, and it is easy and intuitive to zoom in, zoom out, plot the julia set, etc.

Really exceptional work by this developer. - Mike
