Comments on Duct Sizer for Android

★★★★★ fair golfer · Sep 3, 2025

Simple to use, I checked it against a reliable paper version, and they were both the same. 👍👍

★★☆☆☆ Andrew Bellefeuille · Feb 11, 2026

Duct sizing is correct but airflow and fri tion calculations are off by hundreds. Refer to smacnas calculator. Not that. Hard guys. Fix it

★☆☆☆☆ Jaume V · Dec 9, 2024

Is not like they advertised, not useful. The output is preselected.

★☆☆☆☆ Kim Hanson · May 29, 2025

Terrible app. Nothing like depicted in the ad for it. Can't adjust between duct materials. It doesn't even tell you what kind of duct material it's basing things on. Completely useless.
