## What is Hammer Construction Calculator?

The construction calculator that finishes the job: feet-inch-fraction math, 20 trade calculators, and a material takeoff that turns into a professional PDF quote — all in one app.

WHY PROS SWITCH TO HAMMERCALC

FEET-INCH-FRACTION MATH, DONE RIGHT
- Mix feet, inches, millimeters, and meters in one calculation
- Tape-measure fraction strip: tap or slide to enter 1/16s faster than typing
- Results in feet-inches AND metric, side by side
- Custom rounding: 1/16", 1/32", 1/64", or decimal

20 TRADE CALCULATORS — EACH WITH A LIVE DIAGRAM
- Framing: rafters (hip/valley/jack cut lists, birdsmouth), roof squares & flashing, wall framing with stud counts, rake walls
- Stairs: rise, run, stringers — with IRC code checks built in (max riser, tread, headroom, 2R+T comfort)
- Outdoor: decks, fences (incl. chain-link), concrete bags/yards/rebar, baluster spacing (4" sphere rule)
- Finishes: drywall, paint, tile, flooring, siding
- Layout & lumber: square footage with cutouts, board feet & cost, cut list optimizer (fewest boards, least waste), compound miter/crown, triangle & pitch, circle/arc layout
- Every field label explains itself — long-press for a diagram

FROM CALCULATION TO QUOTE — NO OTHER CALCULATOR DOES THIS
- One tap sends any tool's material list to a project takeoff
- Buy-list smarts: rounds up to lengths the yard actually sells, never orders short
- Check off materials on site as you load the truck
- Price book remembers what you paid last time
- Add labor, markup, and tax — export a branded PDF quote with your logo
- Share as PDF, CSV, or plain text

PLANS & NOTES ON THE JOBSITE
- Load blueprint PDFs and photos — auto-saves your page, zoom, and position
- Job notes with one-tap capture of any calculation
- Quick links to your building codes and span tables

BUILT FOR THE FIELD
- Works fully offline. No ads. No popups. No data collection.
- Dark mode for early starts, haptic keys, 12 accent colors
- English & Español — switch live in Settings
- iPhone, iPad, and Mac
