Comments on Easy Offset – Duct Calculator for Android

★★★★☆ tnahern · Apr 1, 2026

How do you get premium I tried that and all I could do on app was to cancel premium. I have tried it asked if I want to upgrade to premium, but the only option is cancel upgrade. Had others asking about it, and they also tried to upgrade and same thing.

★☆☆☆☆ GEORGE HOHMANN · Sep 30, 2025

Rip off, I bought this app on my last phone, and it didn't transfer to my new phone. So I thought I would buy it again, but after purchasing it it only lets you use 1 minimal part unless you buy the premium version. Very disappointed.
