Feet-Inch-Fraction Construction-Math Calculator by Calculated Industries
The official Construction Master® 5 from Calculated Industries is now available for your iPhone and iPad. 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.
Built with the same features and functions, and with the same core engine that powers the industry-standard advanced construction-math calculators from Calculated Industries -- and includes a full User’s Guide built in as well as the ability to press and hold a key for specific help!
Ideal for Contractors, Builders, Architects, Engineers, Tradespersons and Advanced Do-It-Yourselfers
