It’s bad *2025-05-04* So I figured I would give it a try. The area to enter data doesn’t work well. You literally tap all over it and hop to get a cursor. Then it doesn’t really tell you what you need. It just shows catalog pages. No real inflation on how many SqFt of vent we need. ### 3/5 — Pitch view doesn’t work *2023-11-01* The roof pitch screen orientation is off. Please fix. ### 5/5 — Great info *2023-09-06* Simple and easy to use app. Love the calculator to find out how much intake and exhaust is needed. ### 5/5 — All my crew uses this *2019-08-03* Easiest and best way to determine attic ventilation needs. ### 5/5 — Shawn Bellis -EPIC Exteriors (owner) *2019-01-30* This App is a must have for any roofing professional! ## Frequently asked questions about Air Vent ### What is the Air Vent app used for?
