Geometry Calculator for School vs Timed math facts

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.

Timed math facts is math fact practice that pays attention. Every answer you give is remembered. Get 7 x 8 wrong twice and it comes back until it sticks — while the facts you already know stay out of your way. That is the whole idea: practice time spent on the gaps, not on what you can already do. Choose addition, subtraction, multiplication, division, or mix them. Pick a number range from starter to advanced. Answer by tapping or by typing on the built-in number pad, with an optional timer per question or for the whole session. At the end you get more than a score: every missed question, the correct answer, and one tap to drill just those facts again. Track a daily streak, watch your accuracy per operation, and see exactly which facts still need work. No account. No ads. No analytics. Nothing leaves your device.
