QuickBend vs Duct Construction
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
QuickBend
This app is a conduit bending calculator designed for electricians and DIY enthusiasts. It provides accurate measurements for various bend types, accounting for bender and conduit specifications. Users can input data intuitively and receive instant feedback on bend feasibility.
- Accurate centerline radius algorithm
- Supports multiple bend types (offset, saddle, 90°, etc.)
- Intuitive data input (number pad, slider)
- QuickCheck for bend feasibility
- Customizable bender profiles
- Layout multiple bends on a single conduit

QuickBend is the fastest and most precise conduit bending calculator app. Designed to be innovative and intuitive while remaining visually appealing. This advanced conduit bending calculator offers the most accurate measurements by taking into account the radius of the shoe and bender, plus the conduit type and size diameter. All measurements are generated using the centerline radius algorithm, and have all been rigorously processed and field tested. Even the bends displayed within QuickBend are generated using the same engine. Built for electricians by an electrician. QuickBend can be used by anyone working with conduit or tubing whether you are a seasoned professional, a novice cub, or even a DIY enthusiast. Made to avoid simple mistakes, and to save time and money. In addition to providing fast and precise calculations, there is plenty of information and documentation provided for individual bends. Explanations on how to use specific features, and step by step process to bending conduit. Offering the most intuitive method to input data. Whether you want to get straight to the point, or comb through the possibilities of a bend. You can switch back and forth between different input styles such as a number pad, or a slider bar (Press & Slide). Both having their unique advantages. QuickBend allows you, the user to toggle between three different types of measurements; inches, foot + inches, and centimeters. With QuickCheck built into QuickBend, there's a subtle change in text colors when a bend is impossible (red), or whether the bend may be unlikely to work (orange). This app for convenience, and we want it to benefit you. So much so that we added it into the input styles for bends, so you can see if a bend is possible before even tapping on the bend amount. Supporting the following bends! • Offset • Rolling Offset • Matching Bends Offset • Matching Centers Offset • Parallel Offset • Three-Point Saddle • Four-Point Saddle • 90° Bend • Kick with 90° • Matching Bend Kick • Matching Center Kick • Parallel Kick • Parallel Kick: Forward • Compound 90° - Circle Obstruction • Compound 90° - Rectangle Obstruction • Compound 90° - Square Obstruction • Segmented 90° Plus you have the ability to layout multiple bends on a single conduit, and get each measurement for a mark on the conduit. With the option to easily flip an individual or set of marks per bend. There's no limit to QuickBend. Easily, select between different types of benders and choose the size of the shoe and conduit type all within the same screen that you are working on. No need for complex navigations. In addition, you can pin benders you use the most, so you can select and switch between them quickly without consistently scrolling. All benders are spec'd out using the information provided by the manufacturers, and worst case scenario if one of the many benders available don't match the one you are using you can now add in your own bender. There's also an option to not select a bender and to use the multiplier method. Edit and view all of your benders' specifications. Detailed information on the centerline radius, deduct, gain, setback. Plus the ability to view the travel, and radius adjustment for any degree bend between up-to 90°. All of this is visualized and edited within the 'Bender Specs'.
Duct Construction
This app helps determine duct construction and reinforcement options based on duct size and system pressure class. It provides condensed lists of suitable options, saving time spent on manual calculations and table lookups. Results are based on industry standards for galvanized steel duct sheets.
- Duct size range from 2" to 120"
- Pressure classes up to 4 in.wg
- Calculates duct weights per linear foot
- Determines required duct gauge and reinforcement spacing
- Clear illustrations for reinforcement types
- Simple and effective UI design

Get all duct construction and reinforcement options by entering the duct size and system pressure class. The aim of the app is to save time spent browsing through tables and texts to determine suitable options, by relying on the most widely used standards and providing a condensed list of available duct construction options. The results are based on galvanized steel duct sheets conforming to ASTM A653 & A924. The app does not cover all aspects of duct construction, as it is intended as a guide; Reliance on related standards, as well as good engineering sense is the basis for proper design. Features: 1. Duct sizes from 2" to 120" 2. Pressure classes 0.5 in.wg, 1 in.wg, 2 in.wg, 3 in.wg and 4 in.wg. 3. Provides the duct weights for each option per linear foot. 4. Provides required duct gauge and reinforcement spacing. 5. Clear illustration for each reinforcement type, as well as dimensions. 6. Simple and effective UI design. Roadmap / Upcoming updates: 1. SI units. 2. More pressure class options. 3. User will be able to save and retreive duct data for future reference. 3. More Reinforcement options, including tie-rodding.

Verdict
The clearest difference is review sentiment: QuickBend at 81% against Duct Construction's 0%. QuickBend also leads on rating (4.8 vs 1.0) and update cadence (every 2 weeks vs every 10 months). Duct Construction's advantage is price ($0.99 vs $6.99). On ads, in-app purchases, monetization model and device support there is nothing between them.
