A constant ratio exists there. From time immemorial, people have been calling it "GOLDEN RATIO". When you cut off a segment whose length is given by x from a segment of the unit length, the ratio of the unit length to x is equal to the ratio of x to remain. The ratio is 1.618033988... : 1. This is the GOLDEN RATIO. The GOLDEN RATIO guides you make beautiful figures in manufacturing. GOLDEN RATIO CALCULATOR leads to the miraculous ratio that ancient artists discovered with their sensibility. Kazuo KAWASAKI, design director and doctor of medical science, invented this application. All sales of this application are used for Peace-Keeping Design (SDwave, NPO). ■HOW TO USE _____________________________________________________________ 1. Select textbox in which you want to set the length. 2. Input an arbitrary length, and you will get the GOLDEN RATIO. 3.You can select the figure where GOLDEN RATIO is led by flicking the screen by your finger. ■Kazuo KAWASAKI　Ph.D _____________________________________________________________ Design director Doctor of medical science Professor of graduate school of engineering, Osaka University (http://www.kazuokawasaki.jp) ■PKD(Peace-Keeping Design) Project Peace-Keeping Design Office, SDwave, Nonprofit Organization _____________________________________________________________ The objective of this project is the realization of true world peace based on design methodology. There are limitations to conventional peacekeeping operations (PKO), or peacekeeping forces (PKF). This project is named “Peace-Keeping Design (PKD)” and aims to be a global peacekeeping activity. The PKD project takes as its subject various difficult issues faced by humankind and the earth, including war, poverty and environmental destruction. It will seek solutions by comprehensive approaches centered on design and will work towards realizing such solutions.

What happened to the App Store QC??? *****DONT BUY THIS CRAP!!!!!!!******* ### 1/5 — No longer functions *2016-06-17, version 1.0* Press any key and it crashes. Used to work fine. Sorry Kazuo, yo gotta keep your work current. ### 1/5 — CRASH! *2016-03-01, version 1.0* Touch any key and app closes. Enjoy my $.99. ### 4/5 — Works well *2013-01-08, version 1.0* Does it's job, but for design work where you're using a caliper that measures .000" (which is always for me), It would be nice if it didn't chop off that last digit. ### 5/5 — Artist *2012-06-13, version 1.0* Lightning fast, simple to use, and doesn't round numbers. What more do you need? ### 5/5 — A perfect app *2011-05-08, version 1.0* Simple to use. Simple and easy to understand graphics. Just what I was looking for. ### 5/5 — Thank you PKD *2011-02-10, version 1.0* I wanted this application for ease of calculating and constructing painting canvases of any length that comported to the golden ratio and this application fits the bill entirely. The five shapes in the right hand screen shot above are available for the screen shot on the left. For me, it's the rectangle that's the most helpful. This app is simple to use, and because of that, five stars! Thank you PKD. ### 5/5 — Perfect *2010-06-25, version 0* Exactly what I was looking for to help with composing landscape paintings, not necessarily to use but to understand. My only issue is that I wish it were also HD for the iPad and might allow photo import to determine the golden ratio directly from a photo. Maybe version two. ## Frequently asked questions about Golden Ratio Calculator ### What is the Golden Ratio Calculator?
