User Reviews

This app only calculates the total attic ventilation requirement based on the 1/300 guideline - which doesn’t require an app to figure out. What the app should do Is calculate the ventilation obtained using specific soffit and ridge vent types, which is what you need.

Typical of these kinds of businesses, they never follow through with software tools for contractors. So we have to find other alternatives.

The app doe not open on iPhone and does not calculate on iPad. Completely worthless app
