Deck Help is an iPhone application developed by David Caddy that helps you calculate decking material requirements, timber lengths, and associated values when building a deck. With this app, you can quickly find bearer and joist lengths, as well as stump, bearer, joist, and board set outs for a given deck width and length.

Deck Help features an accurate deck equation solver, which allows you to enter lengths in millimeters, centimeters, inches, or feet. You can select your preferred number of decimal places to ensure accurate calculations that fit your specific needs. Plus, the app is incredibly easy to use, making it the ultimate decking material calculator for DIY enthusiasts, builders, and contractors alike.
