It could use some more bells and whistles like code research or ADA information. Over all a must have for the intern and the old man boss!

Not a bad app, but it needs polishing. As is it contains several spelling errors. The formual definitions could be fleshed out a bit more...define each component of the formula more precisely, including which units are employed. For example, under the HVAC section, in Heat Loss, one of the items to enter is "Radiation Value". Is that U factor or R value? Not everyone who may use this app is thoroughly versed in every parameter required for a formula to work, but if they are defined in the app, the user can then know what information is needed or lacking more precisely. This app can be a teaching tool as well as for one who knows the formulas but wants an easy way to use them. I'd give it higher stars pending needed upgrades.

I understand it is impossible to make the apps for every architect needs. I think there are lots of calculations for electrical work but not for HVAC. I hope there will be some calculations to find rectangular and circular duct size, and the chart for the equivalance between them. Also it will be really nice if it has some information from IBC such as occupant load, outdoor air requirement, air balance calculation, and so on. Then you can give us update information as the building code updates in years. Thanks.

Full of errors, incorrect units and spelling mistakes affecting content - nice idea - poor construction

How anyone could screw up an idea this simple this badly, I have no idea. The vast majority of the formulae are of no use to practicing architects, but that hardly even matters because there are errors and inconsistencies everywhere. Many of the formulas don't even use units, rendering them completely useless. Those that do use units, use them inconsistently. Many words are misspelled, the grammar is poor, and the "formula definitions" are often so vague as to be laughable.

For what it does it seems great, however I am missing lots of things. 1) most of the calculations do not indicate the units I am supposed to enter, is the length feet, inches, yards etc. 2) electrical, I would love to see all the NEC tables, for example in the conduit size calc I Ned to be able to select size and cable type from the normal list (16gage THHN) the current calc only works if I know the pursue size of each cable (they are in the tables, why not use it) now I know NEC get updated every few years so if it cannot be include then wy not a new app? I would pay for it; conduit fill, box fill, all the tables from the standard.
