About this app

Pocket Construction Calculator is a set of job-site calculators built for the way tradespeople actually measure: in feet, inches, and fractions — not decimals.

No more converting 3/16" to decimal in your head. Enter measurements the way they're written on the plans, and get answers back the same way.

TOOLS INCLUDED
• Area, Volume & Board Footage
• Stairs (exact-rise and range/search modes for stringer layout)
• Studs on Center
• Circle & Arc
• Roofing (rafter length, pitch, and area)
• Right Triangle Solver
• Pipe Offset — standard and rolling offset
• Pipe Fill & Volume
• Takeouts / Cut Length — buttweld, socket-weld, and threaded (NPT) elbows
• Large Diameter Pipe Reference

BUILT FOR THE FIELD
• Works with fractional inches natively — 1/16" precision throughout
• Calculations run on your device, so a weak signal on site won't slow you down
• Save and revisit past calculations from your history
• Switch between imperial and metric where it makes sense

Every tool is included in a single subscription, unlocked once and available across the whole app — no juggling separate purchases per calculator.

Pocket Construction Calculator is built for framers, roofers, pipe fitters, and anyone who needs fast, accurate math on the job site instead of at a desk.
