Carpenter's Quick Calculations

Carpenter's Quick Calculations is a handy suite of carpentry calculators for pros and hobbyists. It helps you calculate panel spacing, estimate materials for decks and projects, perform trig calculations by entering two values to derive sides, angles, and diagonals, and quickly divide slats, spindles, and fences.

You can also determine last panel widths for roof panels, laminate, tiles, and more. The app includes an on-device protractor using gyroscope/accelerometers and an on-screen ruler to measure nails, screws, and other small measurements. Got a favorite tool team? Let the app colors reflect it!
