Deflection Lite vs PAD Footing
Price, ratings, monetisation and update history for both apps, side by side — with what reviewers say about each.
Deflection Lite
This app provides interactive and precise structural beam analysis. Easily visualize beam bending by dragging loads and supports, and calculate key engineering results like reactions, shear force, and bending moment.
- Interactive beam bending visualization
- Calculate reactions, shear force, and bending moment
- Built-in cross-section databases
- Unlimited loads and supports
- Export design to shareable permalink
- Metric and standard units

Deflection Lite is the most interactive, fast, and precise app available for structural beam analysis. Simply drag loads and supports on the beam, and see how it bends. RESULTS Calculate reactions, shear force, bending moment, and beam deflection quickly and easily. CROSS SECTION DATABASES Specify elastic modulus and moment of inertia values directly, or find common shapes and materials using the built-in databases, which include most international steel sections, as well as some aluminum and wood shapes. UNLIMITED LOADS AND SUPPORTS Simply drag any load or support on the beam. • Concentrated point loads • Distributed loads • Moment loads • Simple supports • Fixed supports • Fixed hinges • Floating Gerber hinges OTHER FEATURES • Export your design to a permalink that you can share. • Automatic detection of local maxima and minima in diagrams • Metric and standard measurement units CONTACT We like to hear from you!

PAD Footing
This structural design tool analyzes single-column footings for vertical loads and bending moments. It's based on a long-standing program, offering reliable engineering calculations for structural analysis.
- Analyzes single-column footings
- Resists vertical loads (Y-direction)
- Handles bending moments (X & Z directions)
- Based on established engineering software
- Structural analysis calculations

PAD Footing is a structural design tool used to analyze simple, single-column footings to resist vertical loads in the Y-direction and bending moments in the X & Z directions. PAD-98 was originally written in 1998 and subsequently included in the Foot2000 program release which is still in publication today.

Verdict
The clearest difference is price: Deflection Lite at Free against PAD Footing's $1.99. Deflection Lite also leads on rating (4.5 vs 3.5) and ratings volume (47 vs 2). PAD Footing's advantage is update cadence (fortnightly vs every 3 months). On ads, in-app purchases, monetization model and iOS requirement there is nothing between them.

Deflection Lite is free to download; PAD Footing costs $1.99 up front. Neither carries in-app purchases, so what you see is what you pay.
Deflection Lite holds the better App Store score, 4.5 against 3.5. That said, the two scores are not equally well evidenced: Deflection Lite has 47 ratings behind it against 2, so its average is the more settled of the two.
Deflection Lite ships an update every 3 months, PAD Footing fortnightly. The most recent releases landed on November 1, 2026 and October 30, 2026 respectively.
