Concrete Bags, Footings, Rectangle, & Sono Tube Calculators with Volume from Rainfall Calc

Available in the App Store

* Featured by Apple in the United States in Productivity > New & Noteworthy

The Concrete Calculator+ app consists of calculators and solvers to help contractors and sales people estimate costs, sizes, and materials amount as well as prices.

• Concrete Bags
• Concrete Footings
• Concrete Rectangle
• Concrete Sono Tube

The Water Collection and Rainfall calculators are designed to calculate the potential and factored water supply of any given enclosure by measuring the interior for the collection of water using length, width, and depth in feet, inches, or meters. The surface area is calculated in square feet, square inches, square yards, and square meters, as well as the potential and estimated actual recovery volume is given in cubic feet, cubic meters, gallons, quarts, and liters.

Water may be collected from any surface, and this app assumes a rectangular enclosure and a constant depth where the water is stored to allow use at a later time for non-drinking water utility, for example, flowers and lawns. Because of direct loss and other factors, such as evaporation, there is a percentage of the actual potential that is very close for collected water volume. In moist cool areas, that may be in the range of 85%, or in the case of dry, hot, desert conditions, it is closer to 60%.

Langelier Saturation Index Calculator


Available in the App Store

The Langelier Saturation Index computes the Langelier Saturation Index, a calculated number, to predict the calcium carbonate stability of water to determine equilibrium. This helps you determine the scaling potential of the water. A negative LSI indicates that the water is corrosive to steel.

The app also features a short interpretation of the the LSI value, and water temperature can be entered as Fahrenheit or Celsius.

This app features:

• Send your calculations or conversions by email
• Universal App (iPhone, iPod Touch, and iPad)
• Retina Display graphics
• Fast app switching
• Automatically Saves Your Inputs
• Latest version of iOS is supported
• iPhone 6, 6+, 5 screens and the original 3.5 inch screen are supported
• Export to CSV
