About this app

Throw away your pencil. Trust your tools.


Standard calculators round your numbers. On a job site, a rounding error isn't just a number—it's a wasted board, a gap in the trim, or a failed inspection.



Carpenter Calc Pro is an industrial-standard carpenter calculator designed for pros who measure in 64ths. Unlike standard apps that convert fractions to decimals (creating drift), our Rational Math Engine keeps every fraction exact.



1/3 × 3 = 1. Not 0.999.



🛡️ THE ZERO-ERROR ADVANTAGE


📏 The Visual Tape Measure (Exclusive)


Don't just read digits. See the cut. The app renders a live, high-contrast tape measure that shows you exactly where the measurement falls. It combines a fraction calculator with a visual readout aligned to industry-standard Red 1F marks.


• Verify 5-3/8" vs 5-1/2" instantly before you mark the lumber.
• Stop squinting at small numbers.



🆕 SMART HISTORY TAPE


• Never lose a number. Swipe up to access your full calculation history.


• Audit your work. Scroll back through measurements to verify your material list without re-measuring.



🧠 The Atomic Engine (Fraction to Decimal)


True Fractions: Calculations are stored as atomic fractions (1/64th precision), not decimals. No drift. No rounding errors.
Smart Input: Type "5" then "IN" then "1 / 2" naturally. No confusion.
Scalar Logic: Effortlessly divide lengths by scalars (e.g., stair stringers: 109" ÷ 15).



🔨 BUILT FOR THE JOBSITE


Feet & Inch Native: Add, subtract, multiply, and divide mixed units instantly.
Tactile Feedback: Feel every button press with integrated haptic vibration (Toggle ON/OFF in Settings).
Rugged UI: High-contrast "Safety Yellow" interface readable in direct sunlight.



🏆 WHO IS THIS FOR?


Framers: Calculate stud spacing and wall layouts.
Finish Carpenters: Precision math for crown molding and trim.
Woodworkers: Exact dimensional analysis for joinery.
Contractors: Verify sub-contractor measurements instantly.



✅ 100% Ad-Free. Privacy Focused. No Internet Required.


Stop guessing. Get the professional standard today.
