ACCA DuctWheel 

Accurate residential duct sizing, the easy way ... now on the iPad! Search for "DuctWheel" in iTunes (on your iPad or PC). 

ACCA DuctWheel is the only duct measurement app powered by Manual D (r), the national standard for residential duct design. And it's the only duct sizing app that acts just like the wheel slide rule that technicians and designers already know how to use, because you've been using it for years! Except with DuctWheel, you can zoom in, lock the wheel, take a screenshot for future reference -- and it never wears out!
