Polygon will allow you to calculate complex and tedious calculations related to any polygonal figure, whether concave or convex, regular or irregular, in a simple and instantaneous way: - Polygon Centroids - Moments of Inertia Ix, Iy, Ixy - Polar Moment of Inertia - Radius of gyration - Principal Moments of Inertia (Iu, Iv and their respective angles) - Area and Perimeter of the polygon - Length of each side of the polygon - Even incorporate hollow sections - Rotate the axes to a custom angle - Define new custom axes at any point - and much more You just have to enter the coordinates of the vertices of your polygon and press the button and it will immediately calculate all the previous properties, saving valuable time.

Verdict
The clearest difference is rating: Beam Engineering lite at 4.4 against Polygon's 3.0. Beam Engineering lite also leads on ratings volume (32 vs 1). Polygon's advantage is ads (none vs shown) and update cadence (weekly vs every 5 months). On price, in-app purchases, monetization model and device support there is nothing between them.

Both are free to download. Beam Engineering lite sells 1 one-off in-app purchase and Polygon sells 4 in-app purchases, starting at $2.99 per month. Whichever you choose, the download price is not the number that matters.
Beam Engineering lite holds the better App Store score, 4.4 against 3.0. That said, the two scores are not equally well evidenced: Beam Engineering lite has 32 ratings behind it against 1, so its average is the more settled of the two.
Beam Engineering lite ships an update every 5 months, Polygon weekly. The most recent releases landed on August 15, 2026 and September 20, 2026 respectively.
