Geometry Calculator for School vs EconoPro

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.

Make sense of prices, choices and the wider economy. EconoPro brings economics lessons, worked examples, visual explanations and practice into one study companion, from everyday money decisions to more advanced economic models. BUILD UNDERSTANDING, STEP BY STEP Go beyond a short definition. Explore how an idea works, see it in a concrete situation, follow a worked answer and try an independent exercise. Common mistakes explain the difference between similar ideas, while extension questions encourage you to justify a conclusion and consider its limits. CONNECT EVERYDAY CHOICES WITH ECONOMIC THEORY Study scarcity, opportunity cost, saving, unit prices, borrowing costs and compound interest. Follow supply and demand, elasticity, production, competition, labour markets and market failure. Then explore inflation, unemployment, growth, fiscal and monetary policy, international trade, exchange rates and development. More advanced topics include strategic decisions, asymmetric information and the assumptions behind economic models. USE FORMULAS WITH CONFIDENCE Find formulas alongside their purpose, symbols, units and conditions of use. Worked calculations show the reasoning, and interpretations explain what a result means. Graphs help you distinguish movements along curves from shifts, read economic relationships and connect visual evidence with an explanation. PRACTISE AND LEARN FROM YOUR ANSWERS Build quizzes using grade, difficulty and reading-based filters. Questions combine realistic situations, calculations and selected diagrams. Plausible alternatives challenge common misunderstandings; explanations help you understand the answer. Review your results and return to the underlying topic when you need more practice. KEEP USEFUL KNOWLEDGE CLOSE Browse terms, facts, formulas and subject references. Search for a concept, save favourites and track what you have read. Choose your text size, colour theme and light or dark appearance.
