## What is Duct Meter?

The Duct Meter is a simple engineering tool to calculate air duct dimensions based on given inputs including air-flow, air pressure static loss (friction method) or air velocity (velocity method). This app was specifically designed with user satisfaction and usability in mind. This app is ready to get the job done anytime, anywhere.

Duct size Calculations utilises long and tedious mathematical algorithms and can sometimes take up most of your day. That’s why we developed this calculator to allow you to focus more of your day on making money and less of it doing math.

This app calculates the dimensions for both round and rectangular duct options. The output also includes air velocity when air static loss is an input (friction method) or it includes air static loss when velocity is an input (velocity method).

This app includes two type ductulators. Classic cardboard style  and modern one.

## Key features

- Calculate duct dimensions
- Friction and velocity methods
- Round and rectangular duct options
- Output includes air velocity or static loss
- Two ductulator styles (classic and modern)

### 2/5 — App crashes

*2022-08-04, version 1.0*

App crashes when you input your values manually. 
After closing and reopening it still crashes - had to delete it

### 3/5 — Good but crashes often

*2022-06-30, version 1.0*

Works well but if it gets too many input at once or something outside of a number entered into the digital calc it crashes. Then anytime you reopen it will immediately crash. So I have to delete the app and reinstall.

### 4/5 — Great easy to use App

*2021-07-28*

Great and easy to use. Just like the good old Ductulator. Only feedback I have is that the digital calculator uses m3/h for volume input where all other sections are per second. It’s just an unnecessary extra calculation the user has to do manually. All units should be consistent.

### 5/5 — Good

*2021-03-10, version 1.0*

I’ve had an app that looks exactly like this but for some reason it isn’t available anymore.
This one is a good replacement.

## Frequently asked questions about Duct Meter

### What are the main calculation methods used by Duct Meter?

Duct Meter uses two primary methods for calculations: the friction method (based on air-flow and static loss) and the velocity method (based on air-flow and air velocity). Both methods help determine duct dimensions.

### Does Duct Meter support both round and rectangular ducts?

Yes, Duct Meter supports calculations for both round and rectangular duct dimensions, offering flexibility for various project needs.

### What information does Duct Meter provide as output?

Depending on the input method, Duct Meter provides either air velocity (when static loss is an input) or air static loss (when velocity is an input) along with the calculated duct dimensions.

### How does Duct Meter compare to traditional duct calculators?

Duct Meter offers two distinct styles of ductulators: a classic cardboard style and a modern interface, aiming to improve user satisfaction and usability over traditional methods.

### Is Duct Meter available on multiple devices?

Duct Meter is designed for iOS devices, including iPhone and iPad, allowing for calculations on the go.
