## What is TradeCalc?

TRY EVERYTHING FOR SEVEN DAYS
Download free and start a seven-day trial of every tool. After seven days, unlock lifetime access for $4.99 once (U.S.; local pricing appears in the app). No subscription or automatic charge. Existing paid customers keep full access at no extra cost. Saved work remains on your device and can be exported after the trial ends. Internet access is needed to start the trial, purchase or restore access; calculations work offline while access is active.

TradeCalc puts construction math and your saved job calculations together on iPhone and iPad. Work in feet, inches, fractions and metric, see what each measurement refers to, and keep the result with its notes and photos.

EVERYDAY MATH, IN YOUR UNITS
Add mixed measurements, calculate areas and volumes, convert units, use percentages and trigonometry, and reuse results from the calculation tape. Memory, saved registers, input undo/redo and repeat equals keep everyday work moving.

32 PRACTICAL TOOLS
Browse grouped categories, filter by trade and pin favorites with a visible star. A compact toolbelt keeps your go-to tools close.
Calculate spacing, diagonals, stairs, rafters, board feet and material quantities. Tools also cover wall framing, crown and compound miters, circles, arches, polygons, concrete, roofing, drywall, paint, tile, decks, fences, masonry and more. Tap numbered diagram markers to highlight measurements. Adjust values with live sliders or exact entry and see results update together. Choose your adjustment step, then undo or redo changes while you explore. Drawing labels reposition to stay readable, with a separate measurement key for crowded layouts.

ROOM TO WORK ON IPAD
See your live diagram beside measurement inputs in wider windows. Use the calculator with its tape alongside, compare cut plans beside stock inputs, and keep saved results beside photos and notes. Layouts reflow as you rotate or resize the window. On iPadOS 18 and later, adaptable navigation adds a sidebar in wide windows.

SAVE THE CONTEXT
Organize editable calculations in job folders. Add notes and up to 12 photos per saved calculation. Draw arrows, place measurement labels, reuse a calculated value, and move or edit your marks later. Undo and redo photo edits as you work. Keep photos with the calculation, share a marked image, or include them in a PDF.

PLAN MATERIALS AND COSTS
Enter supplier prices directly in 12 material and framing calculators, including paint, concrete, roofing, decks and fences. Compare whole-container options for paint and bagged or ready-mix concrete costs. One Settings switch shows or hides material pricing across supported calculators while keeping your entered prices saved.

Prepare cut lists using new stock or boards already on hand. Enter stock quantities, kerf and board prices to compare material use and purchase cost. Create estimates with material lines, labor, markup and tax, then export a PDF.

LEARN WITH WORKED EXAMPLES
Tap a Field Guide example to open the matching calculator with its values filled in. Change an input and try the calculation on your own job.

OPEN TOOLS YOUR WAY
Open any calculator using Siri or Shortcuts. On iPad, use keyboard shortcuts for navigation and undo/redo. Larger text and accessible measurement controls make the toolbelt easier to use.

YOUR WORK, ON YOUR DEVICE
Core calculations and saved jobs work offline. No account, ads or subscription. Export a complete workshop backup with attached files when you want to move or preserve your work.

TradeCalc calculates from your inputs. Photos do not automatically measure distances. Cut planning compares practical arrangements and does not guarantee the lowest possible cost or waste. Verify site dimensions, structural requirements and saw settings for your project. Not every construction assembly or advanced roof/stair configuration is supported.

Requires iOS or iPadOS 17 or later.
