Store description excerpt
The fraction calculator built for the jobsite. Add, subtract, multiply and divide feet, inches and fractions on a big, glove-friendly keypad — then switch to imperial or metric with one tap. Every answer is exact, right down to the sixteenth. Works completely offline. No account. Stop doing tape-measure math in your head. Joist keeps a running tape of everything you calculate, so this morning's number is still there this afternoon. FEET-INCH-FRACTION KEYPAD - Enter feet, inches and fractions with fat, easy-to-hit buttons - Add, subtract, multiply and divide measurements - One-tap imperial to metric (mm) conversion - Exact fraction math — no rounding drift, snaps to 1/16" or 1/32" - A running history tape you can scroll back through - Hi-vis themes for reading the screen in bright sun JOBSITE SOLVERS - Stairs — risers, riser height, treads, total run, stringer length and slope angle, with code-limit warnings - Board feet — total board footage for any lumber order - Rafters — rafter length, run, rise, pitch and cut angle - Concrete — slab and tube/column yardage with a waste allowance - Drywall — sheets needed for a room - Flooring — boxes needed for any floor Every solver ships with a clear, labeled diagram so you can see exactly what each number means. BUILT FOR CARPENTERS, FRAMERS AND BUILDERS Whether you're framing a wall, laying out a staircase, ordering lumber, pouring concrete, hanging drywall or estimating flooring — this does the fraction and material math so you don't have to. A modern tool for the trades: fast, readable in the sun, and honest about its numbers. HONEST BY DESIGN Results are estimates to help you plan and order material. Always verify against your local building code — this app is not a substitute for it. PRIVATE AND OFFLINE - Works with no signal, anywhere on site - No account, no sign-up, nothing uploaded - Your tape stays on your phone Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ — Privacy Policy: https://kanac.github.io/syanac-legal/
