Calculator Air: AI Math Solver

Calculator Air: AI Math Solver is a consumer iOS app from Air Apps Systems, distributed through the App Store as a free download with optional in-app subscriptions. Rather than replacing your phone's built-in calculator with a clone, it layers AI capabilities on top: you can type an expression, use a full scientific keypad, or point the camera at a handwritten or printed problem and let the app recognize and solve it. The headline feature is the step-by-step explanation mode, which the developer positions as an AI homework helper for students working through algebra, statistics, calculus and other coursework.

The app covers a wide range of math levels, from basic arithmetic up to advanced equations, and adds practical extras such as a currency converter with a widget and unit conversions. Because it runs across iPhone, iPad, Mac and even iMessage, it is designed to be available wherever you happen to be solving a problem, including during a study session away from a desk.

Pricing follows the familiar freemium App Store pattern: the download is free and unlocks a limited experience, while full access to the AI solver, tutoring and premium themes comes through a weekly, monthly or yearly auto-renewing subscription. A free trial period is offered and converts automatically unless cancelled at least 24 hours before it ends. There is no desktop web app or team plan — this is a personal productivity and education tool aimed at students, parents and professionals who need fast, reliable answers.
