Jobsite Calc
Framing, Cutlists & Rafters
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Fast, accurate construction math for the jobsite — feet, inches, fractions, framing, and cutlists. No signal needed, nothing to sign up for, works right on your phone.
Stop doing fraction math in your head — or worse, on a scrap of 2x4.
Jobsite Calc is built for framers, remodelers, and anyone who needs fast, accurate construction math without pulling out a laptop or hoping for signal. Enter measurements the way you actually think about them — feet, inches, and fractions — and get instant, exact answers. No more misreading a tape measure or rounding a 3/16" to "close enough."
CONVERT & SHOP MATH
Type it the way you'd say it out loud: 12' 7 3/8" + 4' 11 5/16". Get decimal, metric, and rounded conversions instantly, with a keypad built for fractions instead of fighting a stock calculator.
CUTLIST
Plan a cut list before you make a single cut. Track parts across multiple projects, estimate material costs, export a clean PDF to bring to the shop or send a client, and attach photos and notes so nothing gets lost between the truck and the table saw.
FRAMING & FINISHING
Stud and plate layout, rafter length and birdsmouth with hip/valley/jack support, roofing, siding and trim, crown molding compound miters, concrete and masonry volume and bag counts, and a circular calculator for anything round. The tools that actually show up on a real job, in one place.
Plus a standard calculator and a trig tab for when the math goes beyond framing.
Every calculation runs right on your phone — no signal needed, no account to create, no data collected. Available in English and Spanish.
Less time doing math. More time building.
