DuctSizeCalc vs Beam Calc
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
DuctSizeCalc
Easily calculate duct sizes for air conditioning systems using the constant-pressure method. Input wind volume and tap calculate to determine duct dimensions, pressure, and wind velocity. Useful for blueprints, working drawings, and on-site applications.
- Constant-pressure method duct sizing
- Input wind volume for calculation
- Supports rectangular and circular ducts
- Adjustable friction loss and wind velocity
- Automatic height adjustment for WxH interlock
- Metric system calculations

This app is an application program to which the size of the duct in air conditioning is an easy to select by the constant-pressure method. It is an easy operation only of the input of the amount of the wind and doing the calculation button the tap. An amount of the wind, disadvantageous pressure, and the velocity of the wind can be calculated by an arbitrary size of the duct. Please use it for the reference when you make the blueprint and the working drawing, etc. It is possible to take an active part by various scenes like the site and meeting, etc. [Feature] - The size of the duct can be easily selected only by inputting an arbitrary amount of the wind and pushing the calculation button. - It corresponds to a circular duct besides the rectangular duct. - Friction loss of default can be changed to arbitrary Friction loss. - The velocity of the wind of default can be changed to an arbitrary velocity of the wind. - If Wight of the size of the duct is changed, it is changed automatically to a proper Height size. (When the WxH interlock switch is turning on.) - Friction loss and the velocity of the wind can be examined by fixing by an arbitrary size of the duct. (When the WxH interlock switch is turning off.) - This application is calculated by metric system. - Please see the support site in detail.
Beam Calc

Beam Calc is a powerful structural beam calculator designed for engineers, engineering students, technicians, designers, and anyone who needs fast and reliable beam analysis. Analyze common beam configurations, apply different loading conditions, and instantly calculate reactions, shear force, bending moment, bending stress, slope, and deflection. Whether you're checking a calculation, studying structural mechanics, or performing preliminary beam analysis, Beam Calc gives you the essential tools in one clean and easy-to-use app. BEAM ANALYSIS Analyze several common beam configurations: • Simply supported beams • Cantilever beams • Overhanging beams • Fixed-fixed beams Enter the beam geometry, section information, material properties, and loading conditions, then calculate the structural response. MULTIPLE LOAD TYPES Model practical loading conditions using: • Point loads • Uniformly distributed loads (UDL) • Applied moments • Multiple loads on the same beam Build your beam visually and see how each load affects its behavior. DETAILED RESULTS Beam Calc calculates key structural engineering results including: • Support reactions • Shear force • Shear Force Diagram (SFD) • Bending moment • Bending Moment Diagram (BMD) • Bending stress • Beam slope • Beam deflection Clear diagrams make it easier to understand where maximum shear, moment, stress, and deformation occur. SECTION & MATERIAL INPUTS Define beam dimensions and material properties to calculate section behavior and structural response. Useful for quick calculations involving common engineering beam materials and cross-sections. SAVE YOUR PROJECTS Keep important beam calculations organized by saving projects directly on your device. Return to previous designs without having to enter everything again. PDF ENGINEERING REPORTS Generate professional PDF reports containing your beam information and calculated results. Perfect for: • Engineering calculations • Project documentation • Coursework and assignments • Design reviews • Sharing and printing BUILT FOR ENGINEERS & STUDENTS Beam Calc is useful for: • Civil engineers • Structural engineering students • Mechanical engineers • Engineering technicians • Lecturers and educators • Contractors and designers • Anyone studying strength of materials or structural mechanics Instead of working through repetitive beam equations manually, enter your beam data and get the important results in seconds. SIMPLE. FAST. OFFLINE. Beam Calc is designed as a focused engineering tool without unnecessary complexity. Your calculations and saved projects remain available directly on your device, making the app useful in the classroom, workshop, office, or on site. BEAM CALC PRO Advanced beam configurations, saved projects, and PDF engineering reports are available with the optional lifetime Pro unlock. Important: Beam Calc is intended for educational, preliminary analysis, and engineering calculation purposes. Results should be independently verified before use in safety-critical or final structural designs.

Verdict
The clearest difference is price: Beam Calc at Free against DuctSizeCalc's $2.99. DuctSizeCalc's advantage is in-app purchases (none vs 1) and iOS requirement (9.0 vs 15.0). On ads and device support there is nothing between them.
