## What is Dividers?

Dividers is a set of pocket calculators for the woodshop. It does fraction math the way you read a tape measure, and helps you find proportions that look right.

FRACTION CALCULATOR
• Separate keypads for the whole number, numerator and denominator, so 5 3/8 goes in the way you say it
• Exact math: 1 3/8 + 3/4 is 2 1/8, not 2.1249999
• Round results to the nearest 1/2 through 1/128, up or down, and see which way it rounded and by how much
• Exact, decimal and rounded results side by side
• History of your calculations, and one-tap copy

GOLDEN RATIO
• Enter the long side, short side or overall length and get the other two
• A dimensioned drawing shows the proportions at a glance

BOX PROPORTIONS
• Height, width and depth from proportion sets: golden ratio, root rectangles, Palladian, classical, Fibonacci, and sets inspired by makers like Nakashima, Maloof and the Shakers
• A short note on when to use each one
• A 3D preview you can spin

BUILT FOR THE BENCH
• Works with a keyboard on iPad and Mac: type 5, space, 3, /, 8 for 5 3/8
• Native on iPhone, iPad and Mac
• No accounts, no ads, no tracking, and no internet needed

Measure twice, divide once.
