More than just an app

In school, one teacher is devoted to dozens of students. At Photomath, dozens of teachers are devoted to one student.

Photomath in the classroom

I give this app five stars because of how useful it is when I can't ask my teacher for help.

The step-by-step explanations help me check my kids' homework for accuracy and the app clarifies concepts and improves their independent problem-solving abilities.

I used to hire tutors that were over $100/hour but they often didn't teach in a way that resonated with my kids. Photomath's step explanations are ideal for self-paced learning and it's saving me hundreds of dollars each month!

This app is amazing for kids to help them understand math. As a parent, I don't know too much about algebra and this has helped me with my kid's homework.

I LOVE this app. Every time I show it to students they are just amazed by it (as am I). The fact that it shows alternate ways of solving the equations makes for great learning opportunities that might be missed in a regular class.

This app is EXTREMELY helpful. I'm in 10th grade doing geometry 1 so I don't know how much this counts but for me it's been insanely helpful. 10/10 would recommend. (Not a bot btw)

It's helped me and my friends pass 7th and 8th grade thank you Photomath

Thanks 4 makin me pass 7th grade!

This app helps me with my monomials and fractions. I love this app.

I'm so thankful there's an app like this, it makes me think studying is really easy and fun to do at some times.

Got me through online math 2020-21. I've gotten 90+ marks basically just using this app. Saved so much time. Highly recommend.

This app was very helpful for my daughter. Simple and answers well-explained.

I like how there are multiple options to choose like simplifying or solving for just about any type of problem. I recommend clicking the button that says explain steps because it teaches you really well."

Helps so much in algebra and I like how it gives all formats of answers. It explains the steps very well so that you can understand how to solve the problem.

My son started middle school and his math is significantly more difficult. Photomath shows him the steps to get the correct answer and the lightbulb came on.

Helps me tutor! I love how it allows me to refresh my memory for math I have not done in years.

I forgot so many little things from my math days... this tool helps me help my kids. The easy-to-follow (step) solutions allow me to teach my kids how to do their problems.
