Calculio is a math application that explains word problems, equations, inequalities, expressions, and systems of equations step by step.
Features
Instant problem solving
Take a photo of a math problem, and Calculio provides an instant solution, helping users understand the steps involved.
Interactive mode
Offers an interactive mode that uses questions targeted at common mistakes to help users understand text problems and equation setups.
Parametric equations support
Calculio is unique in providing assistance with parametric equations, offering features like domain determination and restricted operation alerts.
Comprehensive equation solving
Handles all kinds of equations such as linear, quadratic, exponential, and even the most complex ones like goniometric and factorial equations.
Complex expression simplification
Simplifies complex expressions involving fractions, powers, and roots, providing clear step-by-step guidance and explanation.
Voice input for problems
Users can speak mathematical problems into the app, which can recognize and process the spoken input for solution. This is useful for narrative-style or verbally given problems.
Advanced math expression input
Enables users to input complex mathematical expressions using a special keyboard that includes letters, numbers, operators, fractions, powers, roots, and Greek symbols.
Graphical Goniometric Solutions
Utilizes unit circle diagrams to make trigonometric equation solutions more visually comprehensible, resembling textbook methods but with more detail for better understanding.
Multiplatform access
The application can be used both as a web and mobile app, with solutions available across these platforms once a user is logged in.
Credits system for usage
The app operates on a credits system where solving different types of problems consumes a varying amount of credits, allowing users to track their usage easily.
Freemium model access
Users can solve one problem with a solution per day, have two photo captures, and resolve ten problems without step-by-step guidance for free. These limits refresh daily and do not accumulate or carry over.
Premium topics lock
Some higher-complexity topics, such as equations with parameters and word problems, are locked outside of the freemium offering and require additional purchase.
