Golden Ratio Calculator Pro

I made Golden Ratio Calculator Pro for one very specific moment: you are deep in a layout, canvas, frame or screen design, you know one side, and you just want the other number without stopping to do math. Type in width or height, pick a ratio, and the app gives you the matching value right away. Already have both dimensions? Switch to Detect Ratio and the app tells you the exact ratio plus the closest named preset. Choose from 12 built-in presets grouped by category — mathematical ratios like Golden, Silver and Bronze, photography standards like 3:2 and A-Paper, or video formats like 16:9, 21:9 and Cinema Scope. If none of those fit, dial in your own custom ratio with the slider or type it in directly. Save any custom ratio with a name and reuse it whenever you need it. The rectangle preview updates as you go, the color shifts with the ratio, and the calculated value is copied to the clipboard automatically. Small thing. Surprisingly lovely when you do this often.
