Photomath

Photomath is the leading math-solving app, allowing students to photograph a handwritten or printed math problem and receive instant step-by-step solutions with explanations. It has accumulated over 100 million downloads since launch and covers arithmetic, algebra, trigonometry, calculus, statistics, and word problems at K-12 and introductory college level.

The core feature is camera-based math recognition — pointing the camera at a problem in a textbook or worksheet delivers immediate recognition and solving. The AI provides multiple solution methods when applicable (showing both the substitution and elimination methods for a system of equations, for example), and animated step-by-step explanations walk through each solving step. Typed input is also supported for cases where camera recognition struggles.

Key capabilities include camera scanning for printed and handwritten math, step-by-step solutions with animated explanations, multiple solution methods, graph visualization for functions, word problem solving, and a scientific calculator.

Pricing: Free tier includes problem scanning and basic solution display. Photomath Plus at $9.99 per month or $69.99 per year unlocks detailed animated step explanations, multiple solution approaches, and word problem solving. A 7-day free trial is available.

Limitations: Photomath is a step-by-step solver, not a conceptual tutor — it shows how to solve problems but does not build understanding the way Khanmigo does. Heavy reliance on Photomath for homework can impede learning. Advanced university-level math (proof-based, abstract algebra) is outside scope.

Best suited for middle school and high school students who need step-by-step guidance solving specific math problems, and parents helping with math homework.
