The calculator built for your trade.
Exact feet, inches, and fractions — built by framers for framers. The digital tool every framing crew deserves.
Built different. Built right.
Every professional deserves digital tools that actually match the way they work.
Exact trade math
Enter 7′-5 3/16″ and get 7′-5 3/16″ back. No decimal rounding that costs you material. Every fraction stays a fraction.
Built for framers
Construction mode is purpose-built for framing crews — studs, rafters, stairs, board feet, and more. Plain mode handles the everyday math.
AI that knows framing
Ask it "How many studs for a 14-foot wall on 16-inch centers?" and get a step-by-step breakdown — not a generic search result. Pro feature.
Built for the framing crew.
We want to give every framer the digital tools they need. Two focused modes — no bloat, no clutter.
Every formula you'd reach for on the job site.
Stud count, stair risers, board feet, rafter length, pitch angle — built in and labeled so you can find them in 10 seconds, not 10 minutes of scrolling.

Never lose a number mid-job.
Every calculation goes on the tape. Scroll back, reuse values, and share your full work — not just the answer. Built like a paper tape but smarter.
