Amazing geometric concept
by el güije, June 30, 2013

I'm surprised about the absence of reviews for this particular version of geom-e-tree, but in my humble opinion it is one of the most fascinating and beautiful app(s) that I have. I've had it for quite a while. Recently they added color and that made it more beautiful. It deserves 5 shining stars.

And these reviews for earlier versions...

Exquisite Beauty
by Frogzen

Extraordinary beautiful line art is generated with finger control, but you need a delicate touch. Read the help page, It's short and well written.

There are limitless variations possible, but you can't rush through them. This app requires finesse.

A wonderful bit of Apple Math/Geometry Whimsy.
by Faddah Steve Y Wolf

this sort of app is what the original Apple Mac and now the iOS are all about and should continue to be all about. it's simple in its concept and execution, and yet produces smiles and delight with the user interaction with the screen. at the same time, it encourages further investigation of the production of such geometric shapes and the math/science behind it. it does exactly what you'd hope it would do, while making you smile. what more could a user ask from a simple app?
