Worthless

The app changes the input data when calculating. For instance Cd changes from 1.33 to 1.0 and sheathing thickness changes from 1/2” to 3/8”.

Erroneous Results

This app gives erroneous results. I use an online calculator which gives results consistent with the tables in AWC chapter 12. I don’t trust this app.

Great idea, but crashes

This app would be great for a structural engineer like myself. However, after I put in all the info and press calculate, it quits. I haven't seen a solution to my inputs yet. It quits every time. Great idea, just need to fix the crashing.
