Geometry Calculator for School vs AI From Zero

Geometry Calculator is a pure geometry calculator with no AI, designed mainly for schools where in-app subscriptions are blocked. It's ideal for the Volume Purchase Program. The app helps students solve volume, surface area, and perimeter problems with step-by-step solutions and real-time shape previews. You get calculations, theorems, and formulas for all 120 geometric shapes, such as triangles, polygons, prisms, and spheres. There are no ads, and all calculations work offline. The app also includes a weight calculator with built-in materials, and you can add your own materials too.
