T70%
by T####:

Makes very nice pictures which you can zoom to your heart's content, but since the last update was in 2011 I suppose the Dev is too busy or otherwise not able to adapt the app to newer Android versions. On my kit kat tablet I cannot access the controls. Pity!

F70%
by F####:

I sent an email to developer a year ago or more. Because save image doesn't work. He said he will fix it but he has not. I am still sad because this app is so good for fractal explore and I only wish to save my cool findings in hi-res. But I can not. I take a screenshot and crop it but it would be 100 times better to fix the save image function.

H70%
by H####:

No save image, no menu on newer devices so pointless. Was the best: Just spooky beauty, never crashes. Razr and Nexus 7. However, can't save or share results on Nexus. The black and white option is 3D, would be great to have same 3D with the winter sky.

S70%
by S####:

... so now it hangs around the Android Market looking lost, and waiting for someone to care about it enough to allow it to save files again. Apparently not me. Not that sort of dev. Anyway, if you don't need it to SAVE to anything except wallpaper, FINE. Obviously you can screenshot the wallpaper... Assuming you can get the status and nav bars out of the picture... Or crop them out after. (Sigh).

J70%
by J####:

Works really well other than not saving the image on my Galaxy Note 2 (Verizon). Did that just fine on my previous droidx. I have emailed author and haven't heard back. I do have really cool wallpaper as this app otherwise works great.

S70%
by S####:

I quite enjoy this application and all of its features. I only have one complaint- the application does not save the photos. I've looked in every folder and I am 100% certain it is not saving them. I've tried re-installing as well as rebooting my device(Note 2).

X70%
by X####:

This app is very intuitive and easy to explore with. One handy feature is its iteration level auto-select. Another is relative coloring (it doesn't get terribly noisy). That and the simplicity of the control gestures means I rarely have to use the menu. Add a dozen equations, and the ability to set your own coloring modes and colors, and this mobile app sets expectations most PC applications have yet to meet.

O70%
by O####:

This is a 5 star app but rating as a 3 due to the fact the images cannot be saved. There is the option, but it will not save. The 'use as wallpaper' works. Will gladly change rating if the save feature is fixed.

M70%
by M####:

I am unable to svae images, apparently because I can find them nowhere on my tablet. I will change my review to 5 stars when this is fixed.

X70%
by X####:

But I think some more color schemes are needed. As for the saving problem, I've been able to get around that by taking screenshots and cropping out the top buttons and bottom info.

S70%
by S####:

If I save an image, nothing happens. And it doesn't say the zoom level. And maybe you can add deep zooming.

C70%
by C####:

What good is a graphic program whether fractal or image when it is impossible to find where the image is saved. This frustration is in many programs and renders them a useless waste of time.

S70%
by S####:

Its really good. Although i get a problem saving the image or sharing the fractal via any medium...

S70%
by S####:

I have literally made 1000's of fractals and would be making more, but I too have lost my ability to save. Hence the 4 stars. This is so far ahead of any other android fractal program. The variety of equations, colors and algorithms are awesome and then add the ease of use. Fractoid dominates!

V70%
by V####:

I truly love this app but recently it crashes more often than not. I have sent crash reports but get no feedback. I see there have been no updates for more than 2-years...Maybe it is just not supported any longer. Too Bad...There is a sad lack of quality apps out there.

S70%
by S####:

Calculates spatial representations of an arbitrarily small area of the Mandelbrot set. Keep going deeper and deeper; it doesn't quit!

F70%
by F####:

one of the best fractal progs about, being able to select your own colours and colourcycling or lack off are my only niggles, its a beautiful piece of code, well done to the fella that created it!

S70%
by S####:

For some reason I cannot save, share, or create wallpaper on my galaxy s3. Other than that I love it.

X70%
by X####:

this is like androidified fractint. if they used fractint code, they should just say so, people know fractint. oh. took off one star, because can't save. (can wallpaper..)

I70%
by I####:

On my Nexus 7 it can neither share nor save an image, though it can set wallpaper. Otherwise superb -- I have become very good at doing screen captures :-)

K70%
by K####:

The only thing stopping me from rating this app much higher is learning that the 'save' functionality is broken.

S70%
by S####:

I haven't been able to save images except by taking a screen shot and cropping later. This app does render well, and has many options to work with. I would definitely recommend it, as It will remain as part of my top 5 fractal generators.

S70%
by S####:

It gives you the option, but doesn't save. Too bad. This was fun.

S70%
by S####:

I'm used to the fractint, which has a variety of calculation options like boundary tracing mode to avoid calculating the center spots (maximum iteration), and takes advantage of symmetry where possible, but this is still an excellent Android fractal app.

S70%
by S####:

Nice use of the UI for navigating and exploring fractals. Needs a few more color schemes and really needs color cycling like fractint.

C70%
by C####:

The app sets the permission to change wallpaper but not to read/write files, so the "save image" command doesn't really work. Other than this, it's very good!

M70%
by M####:

I spent over 3 hours making pictures and saving them. But when I looked through my photo album they were not there. I love this app but if this does not get fixed I will uninstall and forever give bad review about this to everyone I know.

T70%
by T####:

The fractals this renders are superb, but it fails to save our share images

C70%
by C####:

Thank you so much for this amazing app. I'm always a big fan when an app works so great and does not require intrusive permissions. Runs on every device I ever tried. Like 3 tablets and 6 phones. Tons of options. Love the saves for screen savers. Again thank you for all your hard work on this program. U da Man !

C70%
by C####:

More than 1 year has passed and it was not updated! I want to save the pictures!

O70%
by O####:

I love most everything about this app. It would be nice if it mathed faster, but I guess there's only so much one can squeeze out of these processors.

Z70%
by Z####:

To those complaining about not being able to save an image; just take a screenshot.

C70%
by C####:

I have used quite a few fractal generator applications and I have found this one to rank up near the top in terms of quality. I didn't find it as powerful as some others I have used but it produces top notch results and functions really well in my opinion. Many thanks to the developer for his generosity in offering this free of charge, I'm very grateful. The fractals save perfectly for me. I do hope that one day we can have a full color picker to utilize in the application please. HTC Rezound/ ICS 4.0.3.

C70%
by C####:

I don't think the 10 year old me that first said wow to fractals back in the 80s could have guessed that he would one day own a phone that could make

L70%
by L####:

None of the fractals will save to the device or share to others. The creation process is amazing and can generate beautiful images that, unfortunately, noone will ever be able to see. Without saving, the app is worthless. Fix this for 5 stars!

N70%
by N####:

Opens with the same beautiful fractal every time, but that's all it does. There's no menu.

K70%
by K####:

For WELL OVER A YEAR NOW, FRACTOID HAS NOT BEEN ABLE TO SAVE OR SHARE SUCCESSFULLY... ON ###ANY### DEVICE ##PLEASE## EVERYONE MSG DAVID BYRNE SO HE KNOWS OR CARES ENOUGH TO FIX IT. I DID MSG HIM BEFORE BUT NO RESPONSE... ITS SINCE STORAGE AND SDCARD0/1/ USB CHANGES TO ANDROID... SO SINCE JB??? HAS NOT WORKED PROPERLY... #WAS# THE BEST... NOW JUST #MEH!#

K70%
by K####:

No menu overflow button, so phones with hardware nav buttons cannot access any settings. Extremely slow rendering on Note 4

P70%
by P####:

The app does not save fractals, and when I do set as wallpaper it sets the landscape fractal as my portrait wallpaper resulting in terrible resolution, please fix this app is insanely cool!

K70%
by K####:

Great application indeed, I am plaing with this alredy two years. Why it doesn't save pictres like before ? Before I had HTC Desire, and everything was working well. It is sad that I can't freeze and store my best findings. Still can't save my fractals ...
