Studio Calc
An Architect's Calculator
$1.99
The calculator that thinks in feet, inches & fractions — plus areas, volumes, slopes & proportions. Built for architects, designers, and the trades.
Studio Calc is a calculator for people who work in real-world dimensions — architects, designers, builders, and the trades. Instead of converting feet, inches, and fractions in your head, you enter them directly and get answers in the same language.
Work the way you measure:
• Feet-inches-fractions, entered naturally — 5'-6 1/2" + 12'-3" and you're done
• Imperial or metric, one tap to switch (and it converts what's already on screen)
• Linear, area, and volume — the keypad follows the mode you're in
• Slopes shown as percent grade, rise:run ratio, or angle
• Proportion tools built in: π, φ, √2, √3, √5, and 1:x rectangle splits
• Adjustable rounding, from exact to the nearest fraction or increment
Keep your work in front of you:
• A running tape of every calculation — tap any value to copy just that number
• A conversion panel showing your value in every relevant unit (mm, cm, m, sq ft, acres, gallons, and more)
• Paste any result straight back into the display, or into another app
Designed to feel right:
• Native on Mac and iPhone, with a genuine Liquid Glass interface
• A built-in quick guide (tap the ⓘ) that walks through every feature
Whether you're laying out a floor plan, checking a roof pitch, taking off quantities, or adding up a cut list, Studio Calc keeps you in feet and inches — or millimeters — from start to finish.
