Description
Photomath is a free, camera-based math app that shows the complete worked steps behind a solution, not just the final number. Point a phone camera at a printed or handwritten problem and it walks through the method used to solve it — the difference between a tool that helps a student learn and one that just gives away the answer. Google acquired Photomath in 2023.
Key Features
- Camera-based scanning: Point the camera at a printed or handwritten math problem for instant recognition.
- Full step-by-step solutions: Shows every step used to reach the answer, free, with no account required.
- Multiple solution methods: Displays more than one way to solve a problem where applicable.
- Photomath Plus (paid): Adds animated tutorials that visualize each step, contextual hints, and deeper concept explanations.
- Built-in calculator: Solve typed problems directly, not just scanned ones.
- Broad topic coverage: Arithmetic through algebra, geometry, trigonometry, and calculus.
How It Works
A student photographs a math problem with the Photomath app. The image is sent to Photomath’s cloud servers, where a neural network identifies the problem and determines the correct method to solve it, then returns a full step-by-step breakdown for free. Students who want the reasoning shown visually, rather than just written out, can subscribe to Photomath Plus for animated tutorials that walk through each step.
Technical Architecture & Overview
- Core Engine: Optical recognition of printed and handwritten math, paired with a solving engine that generates step-by-step working.
- Deployment: iOS and Android apps; owned and supported by Google since its 2023 acquisition.
- API Surface: None public — consumer app, not a developer platform.
- Known Limits: Accuracy drops outside its core K-12 range — advanced engineering math, differential equations with complex boundary conditions, and some numerical methods are outside what it reliably handles.
Pros & Cons
| Pros | Cons |
|---|---|
| Core step-by-step solving is genuinely free and unlimited, with no account required. | Math-only — it won’t help with any other subject. |
| Shows the full method, not just the final answer — this is the actual point of the app. | Accuracy degrades meaningfully outside standard K-12 problem types. |
| Covers the full K-12 range from basic arithmetic through calculus. | A student can still misuse it to copy the final answer without reading the steps shown. |
| Works from a photo of handwriting, not just typed or printed text. | Photomath Plus’s more visual explanations sit behind a $9.99/month or $69.99/year paywall. |
Platform Availability
iOS | Android
Best For
Students who need to see the full method behind a math answer, not just the result | Parents helping with homework they no longer remember how to solve | Teachers showing students what a fully-worked solution looks like
