Math help from a photo

Photomath is an education app for students who want help understanding a maths problem rather than seeing only a final answer. Point the camera at a printed or handwritten question, and the app works through the problem with step-by-step explanations. It suits learners checking homework, revising independently, or trying to see where their own working went wrong.

What it covers

The app can break down problems across areas such as arithmetic, algebra, geometry and calculus. Depending on the question, it may show more than one solution method, which is useful when a student wants to compare approaches or match the method used in class. Animated explanations add a visual layer to some solutions, while the calculator supports problems entered manually.

Useful for learning, not just checking

Photomath is most useful when each step is read alongside the original question. The explanations can make a complicated equation easier to follow and give students a way to review a process at their own pace. It should support practice and correction, rather than replace the effort of working through examples independently.

Reach and reception

Developed by Google LLC, Photomath has a 4.3 rating from more than 3 million reviews and has been listed with 100,000,000+ installs. Those figures point to a tool used well beyond a small study group, though its value still depends on how carefully the learner engages with the explanations.
