The Golden Ratio

I am a woodworker and use the concept of Golden Ratios in my wood projects all the time. For years I used a free app that functions very similarly to this one—input the known dimension, with the short or long length, and the app would provide the correct ratio. It went away, so I created this one.
Instructions
This app is straightforward. Select which ratio you would like: Golden, Silver, or Bronze (there are others, these ratios are the most used). Provide the known dimension, either the short side or long side, and press calculate, and the app will provide the other proportion of the ratio you have selected.
If you prefer dimensions in metric, tap the switch, your selection is saved until you tap the switch again.
You can view the calculation results in inches (well, feet too), centimeters, or millimeters dynamically; just select how you would like to view the results.
Please keep in mind that I chose to round off the result as this app is designed to provide a value to meet the eye rather than an engineering exactitude.
The Golden Ratio does a simple task, and you do not need access to the Internet to use it!
Happy Woodworking!
