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.

Safe Distance – Intelligent Safety Perimeter Calculator Stay safe with real-time hazard exclusion zones, powered by GPS and smart algorithms. Safe Distance is your go-to app for calculating and monitoring safe zones during high-risk operations such as pneumatic testing, chemical handling, and blast hazard control. Key Features: Live GPS-Based Calculations: Automatically computes safe distance from your exact location. Dynamic Risk Radius: Factors in pressure, substance type, and other parameters. Weather-Aware Zones: Adjusts exclusion area in real time based on wind and environmental conditions. Instant Alerts: Broadcast evacuation zones to team members via SMS, WhatsApp, or email. Interactive Maps: Visualize safe/unsafe zones with intuitive color-coded markers. Use Cases: Pneumatic and hydrostatic test cordoning Blast zone mapping during demolitions Smart, Simple, Field-Ready: Whether you’re a safety engineer, site supervisor, or field technician, Safe Distance gives you the confidence to manage danger zones quickly and accurately — with zero manual calculations.

Verdict
The clearest difference is in-app purchases: Safe_Distance at none against Polygon's 4. Safe_Distance also leads on iOS requirement (12.0 vs 17.0). On price, ads and device support there is nothing between them.
