C-Calc Pro is a calculator app designed by, and for construction workers. Unlike a standard construction calculator C-Calc uses the power of the IPhone to create a construction computer. This full function calculator works as a standard calculator but more importantly allows you to work in feet, inches and fractional inches. The calculator also features several other modules for performing material estimates, crown moulding, conversions, area calculations and volume calculations, arcs and archs, trig and triangles, and stairwells and stairs. Contractors, architects, tradespersons, builders and even do it yourselfers will find this app ideal. Features include;

- Add, subtract, multiply, divide, exponent, root and more with measurements in feet, inches, and fractional inches.

- Reduce fractions and fractional inches to their lowest common denominator.

- Convert decimal values to fractions and vice versa.

- 50 memory slots to store, recall, add and subtract memory values. Memory values are shared between all modules as well.

- Split screen shows result, memory, and measurement values all at once.

- Calculate square footage and cubic footage easily.

- Conversions for temperatures, distances, angles, areas and many more built in.

- Help screen and full instructions included in program.

- Estimate drywall, concrete, block, paint, tile, lumber and associated materials.

- Transfer individual estimates to a running estimate sheet where you can keep track of your total as well as email the estimate to a man in the field, to yourself, or to the supplier.

- Calculate surface areas and volumes of a large variety of shapes (including compound objects) for material estimates.

- Crown moulding module built in which supports any spring angle and any wall angle. Actually see the saw settings on your phone.

- Trigonometry calculator included for solving triangles, rise/run, rafters, slope, and more. Triangles are graphically mapped on your phones screen to give a visual.

- Advanced arc/circle calculator for solving arcs, radius, circumference, sector areas, sector angles, and circle areas.

- Stair calculator for solving rise, run, unit rise, unit run, # of risers, # of treads, incline, stairwell opening, and stringer length. Drawings are to scale and may be easily printed or saved.

Forget a bulky $100 calculator and simply buy the $10 app. The app will always be on your hip when you need it most instead of in the trucks glove compartment.

C-Calc Pro has much more to offer in the coming months with free upgrades as well. We take our fellow tradesmens opinions very seriously and the app will grow to reflect the peoples opinion.

Pros and cons of Construction Calc Pro app for iPhone and iPad

Construction Calc Pro app good for

I downloaded this app for my husband -a construction engineer, and he hasnt stopped talking about it since! now rather than using different tools he can go to one place for his calculations and conversions! In his words... Awesome!
This app is incredibly useful to me for everything related to construction. It has been crashing from time to time when using some of the estimators though.
The lumber feature doesnt work, every time I click on it Im exited out of the app. If that feature could work this app would be much better than it already is.

Some bad moments

Crashes, wont devide fractions and wont multiply fractions. I used to use it almost every day, now Im looking for its replacement.....payed good money for this disappointment!!
Didnt this app used to have part of the calculator display show the last button that was pushed? An give results in feet-inches as well as decimals? If Im making that up, those would be welcome additions. Thank you
Great app when its working, which isnt that often. Stair calc keeps freezing. Pls fix! Then itll be worth 5 stars.
Now it crashes when entering the arcs & circles categories. All after latest update. Fix it now please. I need it.
I have had this for several months and it is just what I needed. I really like the background colors(dont change it). I give the developers kudos for addressing the recent issues with the update Not many would go through the bother to explain. Again great app Don Updated 11/14 Still believe that this is the best app of its kind Thanks for the continued support with your updates and improvements on an already great app
I would like a refund on this app. The calculator part for squaring triangles is useless. There is no way to enter feet and inches, and the answer comes out in decimal points of a foot. It also changes the angles of the triangle resulting in an incorrect diagonal measurement. Sent an email for a refund. Will see what happens. Do not buy if you want to square up foundations with it.
