Photomath Review: The Camera Maths Solver That Shows Its Working
Photomath remains the lowest-friction maths helper available: point a phone camera at a problem and the steps appear. What makes it better than a plain answer machine is that the steps are free, which encourages checking working rather than just copying a result. Plus adds polish and textbook help, but the free solver alone is enough for most homework checks.
What it is
Photomath is a mobile app, now owned by Google, that solves maths problems from a photo. Point the camera at a printed or handwritten equation and it reads the problem, works through it, and displays each step so you can follow the method, not just the answer. It covers arithmetic, algebra, geometry, trigonometry and calculus, and it is designed for learners from elementary school through college. The basic version is free and includes step-by-step explanations, while the optional Plus subscription adds animated tutorials, deeper explanations and solutions matched to specific textbooks.
Key features
The camera workflow is the core strength: scanning is faster than typing a problem, and it handles handwriting as well as printed text. Step-by-step solutions break a problem into readable stages, with graphs and visual aids where they help understanding. Plus adds custom animated tutorials that walk through a method visually, along with textbook-specific solution paths for learners working from a set book. Multiple solution methods are available for many problems, which helps learners compare approaches and find the one their course uses. The app is mobile-only, with no desktop version.
Pricing
Photomath Basic is free and includes unlimited camera-scanned step-by-step solutions. Photomath Plus costs 9.99 dollars a month or 69.99 dollars a year on the official site, which works out to about 5.83 dollars a month on the annual plan. Plus adds animated tutorials, more detailed explanations and textbook solutions. App store listings can show different in-app offers, so check the price on your own device before subscribing, and note that annual plans are prepaid and auto-renew.
What users like
Users commonly praise how fast and easy Photomath is: scanning a problem takes seconds, and the free steps mean most homework checks cost nothing. Learners value seeing the method, not just the answer, which helps them spot where their own working went wrong. Parents appreciate a free tool that supports homework without a subscription, and the app's high store ratings reflect years of reliable use. For quick checks on routine problems, reviewers often describe it as the first app they reach for.
What users complain about
The most common complaint is that features once free have moved behind the Plus paywall, which frustrates long-time users. Some reviewers report that the app struggles with complex, wordy or unusually written problems, and that it tops out around early college maths rather than carrying advanced courses. Others note the lack of a desktop version and the temptation it creates: because answers arrive so easily, it is simple to copy steps without understanding them. In-app pricing differences also confuse some buyers.
Limitations to know
Photomath is a study aid, not a replacement for a teacher or official marking. It can misread handwriting, misinterpret a problem, or present a method that differs from the one a course expects, so important work should be checked against class material. It also cannot assess understanding, give personalised teaching, or help with subjects beyond maths. Used as a checker after attempting a problem, it supports learning; used as a shortcut for every question, it hides gaps that will show up in exams.
Who it is best for
Photomath suits school and early college learners who want to check homework working, understand a method step by step, or get unstuck on routine problems. It is also useful for parents helping with homework and for adult learners refreshing maths skills. It is less suited to advanced university maths, to learners who need full tutoring across subjects, or to anyone looking for a desktop tool. For those users, a tutor or a broader study platform is a better fit.
Verdict
Photomath earns its popularity by doing one job extremely well and giving the most important part, the steps, away for free. Plus is a reasonable upgrade for textbook help and animated explanations, but it is not essential for most users. Used honestly, as a way to check and understand working rather than to skip it, Photomath is one of the best free study tools in this category. Our editorial score: 8.5/10 — our own judgement, not an aggregate of user ratings.
