Publisher Description

ConCalc (CONtractor's CALCulator) is a feet, inch, mm, and fraction calculator with a much improved triangle solver also included. ConCalc was designed for individuals who frequently perform computations with imperial fractions (draftsmen, estimators, engineers, architects, and or construction personnel).

The objective of ConCalc is to provide a Foot-inch calculator that would be intuitive, easy to use, and fast. Since most professionals who deal with fractions, also regularly solve triangle problems, ConCalc also solves all types of triangle problems (right triangles, acute, obtuse, etc). Just provide three known values, and the calculator will produce the other three un-supplied values.

It is strongly suggested that you review the videos on youtube that demonstrate what this calculator does and how it works. Just search "ConCalc" on youtube or visit

Input in the FT-IN mode: The input key stokes have been optimized for the fewest key stokes possible and will be equal to the qty of digits that represent the feet, the foot mark, one key for the inch, and one key for the fraction. So for example, 12'-11 15/16" will be entered with 5 key inputs: "1", "2", "FT", "11", and "15/16".


The user is required to provide three of the six parts (two for a right triangle: the third angle would be set to 90 degrees) which make up a triangle. The input to this calculator is through the Calculator view:

Step 1: Enter three pieces of data using the appropriate side or angle button.
Step 2: Press "Solve Triangle"
Step 3: View results.

Note: The format of the output is determined by the current mode (indicated by the blue button on the calculator). For example, if the mode is decimal, the output will be decimal. If the mode is FT-IN, then the output will be FT-IN. Angles are always output as decimal degrees.

Requires iOSĀ 4.0 or later. Compatible with iPhone, iPad, and iPod touch.
