## What is Honest TradeCalc?

A construction calculator shouldn't be a yearly subscription. Honest TradeCalc does the dimensional math you actually use on site — and you buy it once, like a real tool.

FEET. INCHES. FRACTIONS. — FREE FOREVER
• Add, subtract, multiply and divide feet-inch-fractions directly: 5' 7 3/8" + 2' 9 15/16" = 8' 5 5/16"
• Exact fraction math under the hood — never a floating-point rounding error
• Multiply lengths into areas and volumes; divide them back down
• Area, volume and unit conversion (feet, inches, yards, meters, cm, mm — 1 inch = 25.4 mm, exactly)
• Big keys that work with gloves on, decimal + metric readout under every result

THE PRO TOOLBOX — ONE PAYMENT, YOURS FOREVER
• Stairs: total rise in, complete layout out — risers, riser height, treads, total run, stringer length
• Rafters: run + pitch → rafter length, exact rise
• Concrete: slab and footing volume in cubic yards, waste %, bag counts
• Board feet: lumber orders priced right, fractional thicknesses included
• Save and name calculations for every job

WHY YOU CAN TRUST THE MATH
Every measurement is stored as an exact fraction of an inch — 6 1/2" is 13/2, never 6.5000001. Every function ships with reference-checked tests (NIST unit definitions, framing-square rafter tables, the board-foot and cubic-yard definitions). And every function shows its work: tap "How this is calculated" to see the formula, the rounding rule, and a worked example. If it ever looks wrong, measure twice and email us — we treat a wrong number as the most serious bug possible.

BUILT FOR THE JOB SITE
• 100% offline — basements, towers, dead zones, airplane mode
• No account, no sign-up, no cloud
• Display precision you choose: 1/16" or 1/32"
• Your saved work is never locked, watermarked, or held hostage

PRIVACY, ACTUALLY
Data Not Collected — that's our App Store privacy label. Your measurements never leave your phone. The only network connection this app ever makes is Apple's App Store for the one-time purchase.

THE HONEST DEAL
The fraction calculator, area, volume and conversions are free forever — prove the math to yourself first. One payment unlocks the pro toolbox for good. No subscription. No ads. No renting your own calculator.

Note: TradeCalc computes geometry and arithmetic only. Verify critical measurements — it is not a substitute for engineered or stamped plans, and it never sizes structural members, electrical, or plumbing.
