Every construction calculation in one place: feet-inch-fraction math plus the complete set of trade estimators, fully offline on the jobsite.
My Construction Pal is a professional feet-inch-fraction calculator with the complete set of trade estimators built in — stairs, roof and rafters, concrete, masonry, board feet, and more, all in one app. No account. Works fully offline, anywhere on the jobsite.
TYPE MEASUREMENTS THE WAY YOU SAY THEM
Dedicated Feet, Inch, and fraction keys. Type 12 [Feet] 3 [Inch] 1/2 and you're working in 12 feet 3½ inches — no decimal conversions, no mode switching. Fractions stay exact and reduce automatically, at your choice of resolution from 1/2" to 1/64". One-tap fraction keys for the sizes you use all day. Yards, decimal feet, and full metric (m, cm, mm) convert instantly without leaving the keypad.
RIGHT ANGLES, RAFTERS, AND ROOFS
Pitch, Rise, Run, and Diagonal keys solve any right triangle on the spot. Common rafters, regular and irregular hip/valley, jack rafter lengths, and the cutting angles (plumb, level, cheek) — plus roofing squares, bundles, and deck sheets from plan size and pitch. Rake walls and arched rake walls included.
STAIRS WITHOUT THE HEAD-SCRATCHING
Enter the total rise and your riser limit: get riser count and exact riser height, treads, total run, stringer length, the stairwell opening, and a headroom check.
EVERY ESTIMATE, WITH COSTS
• Concrete: slabs, footings, and post holes — cubic yards plus 60 lb and 80 lb bag counts
• Masonry: block and brick counts with mortar estimates
• Drywall & sheet goods: 4×8, 4×9, and 4×12 sheets; studs on-center
• Tile & flooring: by tile size or box coverage, with waste %
• Paint: gallons by area, coats, and coverage
• Deck & fence: boards, linear feet, pickets, posts, rails
• Excavation: bank yards and loose yards with swell
• Rebar: grid linear feet, sticks, and weight by bar size
• Board feet: a lumber list that totals feet and cost as you go
• Weight per volume with material densities, circles/arcs/columns/cones, equal-sided polygons, and compound miter settings for crown
Every estimator takes a unit price and shows the total cost, so the number you carry into the bid is the number you calculated.
A TAPE THAT REMEMBERS
Every calculation lands on the tape: review it, recall any value, or share the whole list as plain text for a cut list or material order.
