## What is Feet Inch Builder Calculator?

Built for people who measure, cut and build.

Work directly in feet, inches and fractions without converting measurements to decimals first. TrueRule keeps calculations exact and lets you move between feet-inches, decimal feet, decimal inches, millimeters and meters from the same result.

Use the main calculator for addition, subtraction, multiplication and division with measurement fractions down to 1/32. Keep a running tape of your work, organize calculations by job, bring previous measurements back into the calculator, add labels, and export job records as PDF or CSV.

Trade tools help with everyday construction math:
• Stairs: rise, run, riser height, tread depth, stringer and angle
• Roof & rafters: pitch, common rafter, hip/valley, plumb and seat cuts
• Concrete: volume and material estimates
• Tile & flooring: area and layout calculations
• Drywall: sheet and area planning
• Paint: coverage calculations
• Lumber: board feet and material measurements
• Area: common shapes for jobsite estimating

Designed for jobsite use with large controls, a left-hand layout option and offline operation.

From framing and carpentry to remodeling, roofing and woodworking, TrueRule keeps measurement math in the units you actually use.

## Version history (last 3 releases)

### 2.3.7 — 2026-10-03

General bug fixes and performance improvements.

### 2.3.6 — 2026-09-05

Sharper exports, and a band that was hiding on iPad.

• The tape band is back on iPad in portrait. A nine-point layout error was squeezing it off the screen on the 11-inch and 13-inch models.
• PDF and CSV exports now print every line at the precision you have set, not the precision the line was entered at.
• The PDF preview is drawn at full resolution, so the sheet is sharp on every screen instead of blurred.
• The stair note now cites the right rule when 2R+T falls outside 24-25 inches.
• Fixed a Save button that broke its label mid-word in French.

### 2.3.5 — 2026-09-04

No release notes.
