Carpenter Tools vs Carpenter

Every answer comes with a drawing. Change the wall length and the studs move on the plate. Change the rise and the stair redraws with its risers, treads and stringer, checked against common code limits. What you measured is in black; what you cut and buy is in red. Type it like you read the tape: feet, inches and fractions on a keypad built for lengths. • Wall framing, rough openings, rake walls, stud layout and square checks • Stairs, common rafters, hips and valleys • Decks, fences, concrete slabs, footings and post holes • Sheathing, drywall and flooring • Baseboard, casing, miters and crown, cabinet boxes, face frames and shelf pins • Tape calculator with memory, cut lists, board feet, triangles, arcs and plan scales Feet and inches, decimal feet or metric, on iPhone and iPad. Share any drawing as a picture with its numbers. Always check your local code before you cut.

Construction math, without a crowded keypad. Carpenter helps you work with feet, inches, fractions and metric measurements in a clear, practical calculator. Use it for everyday workshop calculations, then unlock a focused set of tools for layout and planning. TRY 10 CALCULATIONS FREE Your first 10 successful calculator results are free. After that, a one-time Pro purchase unlocks unlimited calculations. There is no subscription or automatic charge. Errors, repeated taps on equals and switching the answer display do not use another free calculation. The free allowance does not renew. FEET, INCHES & FRACTIONS • Add, subtract, multiply and divide measurements. • Enter mixed fractions such as 5 1/2 in or 2 ft 3 in. • Pick common fractions using a scrollable 1/16-step wheel. • Switch answers between decimals and simplified fractions. • See a separate nearest-1/16 tape reference when needed. • Keep full precision for the next calculation. • Label measurements A and B and calculate with them. UNLOCK THE PRO TOOLBOX • Unlimited calculator results. • Equal spacing for decorative slats and panels, including gaps at both ends or flush-end layouts. • Cumulative set-out marks measured from the left edge. • Target diagonal, rectangular area and perimeter, board feet, and rise/run/angle calculations. • Phone angle level with hold and a relative zero reference. • Approximate camera measurements on supported devices. • Saved calculations and plans, with PDF sharing. YOUR WORK STAYS WITH YOU Core calculations and tools work offline. No app account, advertising or usage analytics. Measurements, saved plans and history stay on your device; system backups may include them. An internet connection may be needed to buy or restore Pro. If you choose to submit feedback, your message, optional email and app/software versions are sent to our private Cloudflare-hosted feedback service. Your saved work is not attached. History, saved work and existing exports remain accessible when your free allowance ends. Pro pricing is shown in your local currency before you confirm a purchase with Apple. MEASURE, THEN VERIFY Camera distances and phone angle readings are approximate. Device support varies. Verify dimensions with suitable physical tools before cutting or building. The app calculates geometry; it does not certify structural safety or building-code compliance. A finer display is not a guarantee of measurement accuracy.
