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.

Verdict

The call

The clearest difference is price: Construction Master Pro Calc at Free against Construction Calculator++'s $0.99. Construction Master Pro Calc also leads on rating (4.8 vs 4.2) and ratings volume (40K vs 49). Construction Calculator++'s advantage is in-app purchases (none vs 20) and review sentiment (75% vs 60%). On update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Construction Master Pro Calc holds the better App Store score, 4.8 against 4.2. That said, the two scores are not equally well evidenced: Construction Master Pro Calc has 40K ratings behind it against 49, so its average is the more settled of the two. Written reviews complicate that: 60% of Construction Master Pro Calc's written reviews are positive against 75% of Construction Calculator++'s, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly every 3 weeks. The most recent releases landed on September 29, 2026 and September 24, 2026 respectively.
