Patio Calculator Plus is a useful tool for anyone looking to build a paver, concrete, or gravel patio. Developed by Calc Hub LLC, this iPhone app offers 7 different calculators to estimate the materials needed for patio construction.

With the Concrete slab calculator, you can easily determine the amount of concrete required for your patio. The Pavers calculator helps you estimate the number of pavers needed, while the Paver Base calculator calculates the amount of base material required. The Polymeric Sand calculator helps you determine the quantity of sand needed for the joints between the pavers.

The Sand & Gravel calculator is useful for estimating the amount of sand and gravel needed for your patio project. The Area calculator allows you to calculate the area of your patio, and the Volume calculator helps you determine the volume of material needed.

One of the great features of Patio Calculator Plus is its flexibility in entering dimensions. You can input measurements in inches, feet, yards, centimeters, or meters, and the app provides results in both US customary and metric measurements.
