Awesome

This app is amazing, I use it all the time. Very accurate and simple.

Dear Allen,

Can you make it so we can fill in the cut joint length,
Centerline length, and overall length?

Happy with what it is but not really handy unless you have fittings

Okay for what it is, if you have fittings. But just use the good old owl method if you have to figure out a pie offset in your duct.

Well

Not as good as the android version.....

It’s worth it!!!!

I’ve done several exposed spiral jobs where the pipe needed to stay slammed to the deck and drop at the last second for the perpendicular run. Of course Once you know your measurements/radius’s and allowances this is sooooo easy to use and layout with. I finished the whole floor before one side of the building was tossed up.

Thank you for updating to 64bit. Just a thought though update the author email address, no one ever answered my emails.
