H & S Construction Calculator

Hello my name is Brian and this is my first app. I built this app for checking the square or diagonal of two walls using feet and inches for the input and output. In my case the walls are concrete and getting them square is very important. We have used a rather pricy construction calculator for this but they often break or need batteries, so this is the replacement I present.

How to use:

Start by touching the number entry box labeled feet for Wall 1, a number pad will appear, now enter the length in feet. Most phones will have an arrow key on the number pad in the bottom row that will move to the next box, if not you will need to touch each entry box if entering a value. Leaving a box blank will enter zero for its value. Once all values are entered touch the check box on some number pads or click the back arrow on the phone to remove the number entry pad and click CALCULATE.

To clear all values hold the RESET key for approximately 3 seconds.

How it works:

App uses the Pythagorean theorem so the walls or lengths must be at a right angle. The value for each wall is converted to inches and then a diagonal of inches is converted to feet and inches. Values calculated to the nearest 16th of an inch.

Not responsible for miscalculations.
