Ductulator - Duct Sizing App Comments & Reviews

Ductulator - Duct Sizing Positive Reviews

OptionsI love the App. It’s easy to use I just wish there were more options like selecting round or square duct as opposed to just only using Cfm..Version: 2.2.2

Solid app, not quite 5/5The only thing holding the app back IMO is the omission of flat oval ducts. They’re uncommon, but it’s the only thing the app can’t do that has caused me to have to reach for the less convenient methods..Version: 3.4

Don't be afraid to invest in this very useful tool.Excellent application. Don't be afraid to invest in this very useful tool. The application perfectly meets its objective. I recommend it 100%.Version: 3.3.1

Best duculator for IPhoneVery easy to use in the field. I use it everyday when measuring out duct runs !!.Version: 3.3.8

Pretty usefulComes in handy but limits what sizes you can pick. Not sure if it’s a bug but I wanted to see what my friction rate was for 16x25 and I can get the 16 but it skips from 24-26 and that happens often..Version: 3.3.5

It’s a must haveI get to retire my 25 year old Ductulator.Version: 2.2.1

Let me reverse lookupLove that it gives you different options for sizing but I wish I could enter a duct size and get a cfm value from it..Version: 3.3

Needs workThe new flex option isn’t working properly..Version: 3.3

No Flex in duct calcsSadly, $2.99 spend, to discover it’s useless to me, without having the option to select “Flex” in duct calculations.Version: 3.1.1

Duct DesignAn excellent tool to have for duct design. Seamlessly transitions between imperial and metric values when duct sizes are metric with imperial airflow quantities. Saved me a lot of time and the app is very easy to use..Version: 3.3.8
