The creators of top ranked Statistics Calculator++ for iPhone and Statistics Calculator+++ for iPad, present Construction Calculator++, designed for construction math solutions and unit conversions. Construction Calculator++ comes with the following features: - Length-Width-Height Module: You can enter Length, Width, or Height values in Yard-Feet-Inch-Fractions, Decimal Feet, 
Decimal Inches, and Yards. Enter the Length and Width to calculate Area, Perimeter (of a room), and Square-up. In addition, enter the Height to calculate the Volume, Wall Area, and Total Room Area. You can enter any single length value and convert it to other dimensions, for example from Feet-Inch-Fractions to Decimal Feet or Decimal Inches or back. Furthermore you can tap on any calculated dimension to convert it to other dimensions. If the calculated value is Volume you can tap and see its conversion to Board Feet. - Bricks/Blocks/Pavers/Tiles Function calculates the number of Bricks/Blocks/Pavers/Tiles needed for a certain length or area. You can use the standard 8-inch x 16-inch size block/mortar (area of 128 square inches) or enter custom block size by height and length or area. Furthermore, this function allows you to quickly and simply add a waste allowance to the number of blocks calculated. - Drywall Sheets Function calculates the number of 4 x 8, 4 x 9, and 4 x 12 feet sheets required for an area or length. Furthermore, you can add your own custom size of Drywall Sheets. - Add, subtract, or convert linear measures with different units. The units include yard, feet, inches, inch fractions, meters, centimeters and millimeters. - Rafter Module: Enter any two of the four parameters, Rise, Run, Diagonal, or Pitch to calculate the unknowns. Run, Rise, and Diagonal values can be entered in Feet, Inches and Inch fractions or Decimal Feet and Decimal Inches. Pitch can be entered as a dimension in inches which is the amount of rise over 12 inches of run. Furthermore, Pitch can be entered as an angle in degrees, a percent grade or slope (pitch ratio). Tap on any of the values to see its conversion to other formats. In addition to Common Rafter, you can perform calculations of Regular and Irregular Hip/Valley and Jack Rafters. You can also calculate Plump and Level cut angles. Simply enter known values of Common Rafter and you are done. Length and cut angles of the adjoining Hip (or Valley) rafters, Incremental Jack Adjustment, Regular/Irregular Jack Rafter Lengths and Cut Angles for 16 Inch On Center Spacing are all automatically calculated. You can also enter an On Center Spacing other than 16 Inches. - Circle and Arc Module: Solves for parameters of circle and arc. The parameters include radius, diameter, area, circumference, arc length, arc angle, chord length (run), segment rise (rise), segment area, and pie slice area. A plot of circle or arc and its parameters is drawn to scale to visualize the parameters for you . - Shows the expression as you enter and keeps a history of your calculations (Swipe up on the screen to reveal the history) - Capability of performing fraction manipulations and converting between different formats (proper, improper, and mixed fractions) and seamless integration of fraction, integer, and decimal manipulations. - Capability of inputting degrees, minutes, and seconds for angles and converting between degrees-minutes-seconds format and decimal format. - The left pane scrolls to reveal more functionality without a need to switch modes. The digits and most common operations are always visible and the less common operations can be revealed by scrolling the left half of the screen. - Sinusoidal functions can be calculated for angles in units of degrees, radians, or gradians.

Solve any right triangle in seconds — no formulas, no calculator gymnastics. Right Triangle Calculator does the trigonometry for you. Enter any two values — two sides, a side and an angle — and it instantly computes everything else: the missing sides, both angles, and the hypotenuse. It's built for people who measure in the real world, so you can type the way you actually work: feet and inches, fractions, or metric. Whether you're framing a wall, cutting a rafter, laying out stairs, building a deck, or checking homework, the answer is one tap away. REAL-WORLD MEASUREMENTS • Mix feet, inches, and fractions — type "5 ft 3/8 in" directly • Work in metric too — meters and centimeters • Set fraction precision from whole numbers down to 1/64" • Control decimal places for clean, readable results SMART TRIANGLE SOLVER • Enter any 2 of 5 values (sides a, b, c or angles A, B) • Side c is always the hypotenuse, angle C is locked at 90° • Automatic conflict handling — change your mind and it keeps up • Powered by the Pythagorean theorem and trig, done instantly SEE IT, DON'T JUST SOLVE IT • Live diagram redraws as you type • Rotate the triangle to match your layout • Clean, labeled sides and angles you can actually read ARC & CHORD MODE • Switch to curves to solve chord, arc length, and segment height • Perfect for woodworking, masonry, and curved layouts MADE YOUR WAY • Choose label color, label size, and decimal precision • Optional tap sounds • Fast, offline, and distraction-free PERFECT FOR Carpenters • framers • woodworkers • DIY builders • roofers • machinists • students • teachers • engineers • anyone who needs a fast right-angle answer. Just measure, tap, and build.
