Brace is a construction calculator for feet, inches and fractions, with the work shown. Use the calculator and conduit-bending tools free, without an account or subscription. FRACTIONS YOU CAN CHECK Enter measurements such as 6' 3 5/16" or 6-3-5/16. Calculator arithmetic retains exact fractions. Results that need rounding are marked with ≈. Choose precision from 1/2 to 1/64, and view an answer on a tape measure. KEEP AND SHARE THE WORK Open Show Work to see formulas, inputs and steps. Save a worksheet under a job or calculation name, find it later in Saved worksheets, or share its working. Saved results retain their original display units and rounded-result markers when preferences change. FOR ELECTRICIANS Calculate offsets, 90-degree stub-ups, and three-point and four-point saddles. Offsets support field multipliers or labeled trigonometric results at 10, 22.5, 30, 45 and 60 degrees. Stub-up marks use published take-ups for Klein, Ideal and Greenlee hand benders: EMT from 1/2 inch to 1-1/4 inch, rigid from 1/2 inch to 1 inch, and IMC from 1/2 inch to 1 inch (Klein IMC to 3/4 inch). Edit a take-up or add your own bender and sizes. Your values are saved locally and labeled in Show Work. If a take-up is missing, Brace asks rather than guesses. FOR PIPEFITTERS Find true offset, travel and run for rolling offsets using 11.25, 22.5, 30, 45 and 60-degree fittings. LAYOUT, CONSTRUCTION AND MATERIALS Brace Pro adds stairs from total rise or target run; common, hip and valley rafters; squaring and diagonals; on-center stud and joist layout; grade and slope; sheet goods and roofing with waste; crown-molding miter and bevel settings; arcs from chord and rise; concrete, board feet, and area coverage. View rise, tread and slope reference checks alongside results. Verify the requirements for your project. Brace does not size beams or headers. ONE-TIME PRO UPGRADE The Calculator and Bend tabs are free. Brace Pro unlocks the layout, construction and materials solvers with one purchase. Nothing renews. Restore Purchases is available. Calculations and saved worksheets work offline. An App Store connection is used for purchases and restore. No ads or analytics tracking. Worksheets stay on your device unless you choose to share them.

Verdict
The clearest difference is in-app purchases: Piston Fuel at none against Brace's 1. Brace's advantage is update cadence (weekly vs monthly). On price, ads, device support and iOS requirement there is nothing between them.
