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 in-app purchases: TCI Bitacora at none against Polygon's 4. TCI Bitacora also leads on iOS requirement (11.0 vs 17.0). Polygon's advantage is update cadence (weekly vs fortnightly). On price, ads and device support there is nothing between them.
