Yard, Feet-Inch-Fraction, Metric Heavy Construction Math Calculator from Calculated Industries®

The official Heavy Calc Pro from Calculated Industries is now available for iPhone and iPad users. And while perhaps obvious, if you change from an iOS device to a non-iOS device, you WILL need to buy a new license as they are incompatible.

It helps engineers, excavators and heavy construction professionals cut estimating time, improve design accuracy, and reduce material and labor expenses. Increase efficiency in the field or in the office with fast, accurate solutions for square-ups, cut/fill, swell/shrink, areas, volumes and loads.

Built with the same features and functions and the same core engine that powers the industry-standard handheld HeavyCalc Pro from Calculated Industries.

Need to quickly and accurately solve a dirt or excavation problem for a job? Do it on your iPhone or iPad anytime, anywhere instantly.

Missing opportunity

Most other iPad apps can go split screen or have another smaller window overlaying a full screen app. This app seems 1/2 functional. Imaging doing a quick estimate not only having your email up but also this calculator app. I would change my rating if this feature gets added ASAP. 04/26/19
