Pro grade ductulator
Been in the HVAC trade 18 years and this app is an absolute game-changer. Quick CFM-to-duct sizing, round-to-rectangular conversions on the fly, friction loss, all right there on my phone. Saves me time on every job, especially on commercial takeoffs.
Another deceptive application
Stay away from it. Nothing in the description suggests that any charges. However when you get it installed, you are hit with the highest subscription fees. They tell you that you can use it for 7 days for free but want you to sign up right away and lock any calculation results if you don’t. Say it upfront. Don’t lie.
