Comments on Ductulator - HVAC Duct Sizing for Android

★★★★☆ Vaibhav Savani · Oct 18, 2024

Useful App for Immediate tentative Duct sizing on sites.

★★★★★ Richard G Wallen · Apr 17, 2026

Better than my Trane ductulator - I used this for a year on the iPhone. I've since traded that in for a Samsung so bought it again. The features are a little different. One thing I miss is to be able to "size" vs design by switching from flex to rectangular or square duct. I use this to cross-check my Manual D where I can see the friction loss across distribution boxes and triangles. Are you considering a PC version?

★☆☆☆☆ Aaron Wicklund · Nov 16, 2025

If you can't use the full functions of an actual ductulator what is the point? I want my money back!!!!!

★☆☆☆☆ Jason Towers · Jan 5, 2024

Pretty much worthless. Can't enter dimensions without a CFM measurement. Measuring the duct for system replacement (usually inoperable) I want to know what it can handle at WC

★★☆☆☆ ENGIN333R · May 13, 2023

Disappointed, I was expecting it to be more flexible with the Units, but I was stuck with m3/hr, an I need to use L/s, so if I'm going to use this app I would have to do so many units conversion for a ducting design of a building.

★☆☆☆☆ Kerry Nardi · Jul 25, 2024

Completely unnecessary. A shame that we value using our brains so little that we wish to open source a skilled trade that requires training and field experience to understand. Every certified trade can do the math in their head. Useless.
