Missing a lot of stuff…

I haven’t used this app for a long time and have instead been using RetinaMandelbrot. Fractally has a lot of stuff missing. First of all, infinite zooming. That is one of the reasons I use RetinaMandelbrot instead. I just love the insane complexity of deep zooms, and I just can’t do that in your app (PS: RetinaMandelbrot also kinda has that same issue, but instead the fractal completely goes black, and weird colored (I guess lag) blocks appear that don’t match the iterations, but all of that happens at about 5.7 x 10 to the power of 85 zoom. Not when you’ve barely even zoomed in. Secondly, infinite iterations. This kind of goes with the infinite zooming thing. You could keep it the same as you currently have the iteration editor. Just don’t have a limit. Or you could make it so it adds more iterations as you zoom in (that is how RetinaMandelbrot handles it’s iterations btw). Finally, custom color palletes. Some of the set palletes you currently have, I don’t like. Plz add custom colors. Or at least let people edit how the iterations look. Like only having the lines for the iterations and not filled in. Plz add these features. It will really improve the app.

Thanks!

Pretty neat but…

I can’t zoom in infinitely as it makes me nor able to zoom in after a few zooms

Yes, the zoom's are limited - to 10,000,000,000,000 x. At the point the zoom's stop, the app has reached the limit of the double precision floating point (IEEE double) precision. Double precision floating point uses 52 bits for its mantessa, 11 bits for the exponent, and a sign bit making 64 (FP64.) To zoom further we need arbitrary precision floating point, and I've experimented with this, but its horribly slow. The hardware handles FP64 and things like multiply and add take one cycle. With arbitrary precision, this goes up to many dozens of cycles per multiply. The app would be sluggish beyond reason - and your review would be complaining about how slow the app is, instead of how its zooms are limited haha. I've favored speed and interactivity in the app over infinite zooms. Trust me, this is the better tradeoff.

loads. does nothing.

nothing you click on does anything. Not sure that this app actually works. Deleted.

I just noticed this review, 7 months late, oops, sorry for the delay. The app does work, but I noticed a problem that happened when I first ran the app and the view was completely zoomed out, where the menus and buttons were unresponsive. Then I zoomed in (via the pinch gesture) and everything works again. Now I can't reproduce the issue no matter what I do. Strange. I have no idea why the app froze like that - but if you can zoom in (via pinch, scroll wheel, etc) then the app should "unlock". Also, this issue seems to not affect very many people, as many others are downloading the app and using it. If you are curious about the Mandelbrot set, Julia set or the Mandelbrot orbit shapes, the app is definitely worth a spin. Try again. Also, I can be contacted at fractally@luckgrib.com, that is a better route to resolve an issue than an app store comment, if you are interested in resolving the issue.

Takes me back to playing with 'Dragon' on Silicon Graphics workstations in the 90s

What fun - zooming into the edge of the Mandelbrot set, Julia sets updating almost instantaneously - nice set of colour palettes - trip down memory lane but with breakneck speed - what's not to like!

I was also around in the 90's using SGI workstations and "reality engine"s, watching graphics come alive. Good times. Our computers, and phones(!) are so much more powerful today. It's hard to comprehend how fast they are. Thanks for your review!

Fractal nerds rejoice

This is a Great! fractal app. I highly recommend it & I have spent many hours using a variety of such applications.
Enjoy :-)

Thank you!

Desperately needs color cycling

C'mon man, that's been around for 30 years with this stuff. Decent program that needs clearer navigation. At least on Mac.

Good, not great

The zoom and pan controls to find interesting areas to explore are great. Resolution is outstanding. Seeing the interation between sets is facinating. Only wish that there was more contol over the color pallet

Very good for a free app

My 8 year old has now explored for hours, full of excitement. Overall greaet to play with.

Pros
- very fast, good use of graphics card it seems
- nice split screen option with Julia set
- simple but elegant interface, including simple colour option cycling

Cons
- Max iterations at 2k, but takes you to 1e10 zoom nicely
- Zoom of pan and scroll using bottom bar is visually smooth though I found it a bit clunky
