Deck Help for Android

David, the deck designer is creating overkill for the stumps, bearers, and joists. A 10’x17.5’ deck has 20 bearers and 8 joists which is far too many. In setup you have the default bearer width set at 4” and joist width at 2”. No builder is going to use material that weak for a deck. A 6”x6” or 8”x8” would be used for the stumps depending on the height. If it’s really high a 12”x12” might be used. A 2”x12” and 2”x10” would be used for the bearers and joists. I’m not sure IBC rules even let you use material that weak for deck support. If you make these changes your users will likely be much happier with the software. Maybe from a engineering and weight support perspective your numbers are correct but it takes far too long to dig holes for all those stumps and lay that many bearers and joists. What you might have saved in material you will spend twice as much in work hours.

Needs more directions and features. Pretty much not worth the money at all

Been building decks for years and you will never get accurate numbers using this app. Not exactly sure where their numbers come from but they are incorrect anyway you look at it.
