'AirDiffuser' is an application program that can select air ceiling diffuser in air conditioning facilities quickly, and easily. It is an easy operation only of the choice of the apparatus to be examined from the list, the input of the amount of the wind, and doing the calculation button the tap. It is possible to calculate to examine the velocity of the wind to select the size of apparatus and to examine the amount of the wind. Please use it for the reference when air ceiling diffuser is selected when the blueprint and the working drawing, etc. are made. It is possible to take an active part by various scenes like the site and meeting, etc. [Feature] - The size of apparatus can be easily selected only by inputting the amount of the wind and pushing the calculation button. - It corresponds to various apparatuses. (Round Diffuser,Square Diffuser,BL,CL,VHS,HS,OAG,EAG,Smoke Damper) - The aperture rate of default can be changed to an arbitrary aperture rate. - The velocity of the wind of default can be changed to an arbitrary velocity of the wind. - The velocity of the wind can be examined by fixing by an arbitrary size of apparatus. - The amount of the wind can be reversely calculated by fixing an arbitrary size of apparatus and the velocity of the wind. - When size L is selected, BL and CL round length and are computable. - 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 AirDiffuser's $2.99. AirDiffuser'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.
