MBrot7 is a simple tool that allows you to investigate a fascinating mathematical function (the Mandelbrot set) that reveals new beauty at every new scale. The amount of astoundingly beautiful images you can create with this tool are infinite. The interesting parts are in the boundary around the dark turtle.

• Move the image with one finger to change the center
• Spread or squeeze with two fingers to change the scale

• The left arrow on the top allows you to go back to the previous image one time. This is helpful if you moved away from an image you intended to archive. After you use the back button, you must perform zoom or re-center operations in order for that back option to work again.
• The slider allows you to choose between fast imaging time and high resolution.
Start by keeping the slider left at 60 for the fastest speed. When you come to an image that has some black in it, push the slider to a higher number. This will provide higher detail at the cost of picture paint time. Push the slider all the way to the right for the finest detail.

The four tools along the bottom work as the follows: (Toolbar icons provided by app-bits.)
• The leftmost tool retrieves from saved images. It presents a palette of saved images and allows you to select on to display on the main screen.
When the thumbnails are displayed, One tap selects an image, two taps also select an image, and three taps gives you the opportunity to delete an image.
• The next tool saves the current image to the archive. Please note that the archive images are not saved to a particular detail. You can increase their detail with the slider.
• The third tool (home) reloads the original “turtle picture”. Remember you can go back to the previous image with the left arrow if you press reset by mistake.

When you are retrieving a saved set, you can long press any set to allow for removal.
Enjoy MBrot7 and use the images wherever you like!

Ratings and Reviews

New version 5.3


MBrot7 has been rewritten to support the iPhone 5.
The images are sharper on retina displays.
The pinch gesture takes precedence over the pan gesture making zooming easier.
You can type the value you want for detail, color spread, color shift, and lightness.
There is an info button for you to see and change the scale and center.
The detail limit has been increased to 6,000.

Hot mess. Don't buy.


Nothing works on this app. Super disappointed I spent $3 on this.



I love the Mbrot's ....This would be great if it worked.
