BuildCalc - Advanced Construction Calculator
Probably the best construction specific app available. Essentially a calculator for the iphone, a lot of time has been spent fine tuning for construction specific tasks.
No more head scratching or fishing out those old textbooks to remind yourself of the equations required for hip roof calcs. Buildcalc has a dedicated button for this with all the required data self-calculating once you’ve inputed some basic parameters.
An invaluable time-saving tool for builders, architects, and surveyors. BuildCalc also benefits from extensive supporting information through its web-site and downloadable user manual.
