Works well, probably one of the better apps to use for difficult math problems. Its definitely saved me countless amount of times for school, and I love that it explains how to solve it with many steps and multiple ways of explanation. Just wish it understood word problems.


Awesome app! It's really great for when I'm doing homework or studying and need help understanding the process. The only issue I ever have is sometimes my camera doesn't focus and I can't take a picture, but if I exit out of the app and go back in that usually fixes the problem. Absolutely recommend!! (It does have a premium version, but the free version works better than fine!)


Very easy to use. Feel like there could be more options for different things. It just seems very minimal and basic, like take photo, solve, explain, done. Which is great, I just want to be able to write equations and such. But over all, def worth 5 stars,⭐⭐⭐⭐⭐


This has helped me so much in Algebra especially since they provide each step to get to the solution so you can see where you messed up. They also graph functions for you and that feature is amazing! They also don't have an overwhelming amount of ads. The app also has a feature where you can look up you textbook and the from the problems in the book.


Edited: I have found multiple problems with incorrect answers. I still find it useful but have spent a fair amount of time chasing my tail. I am taking precalc classes at home, so this is the closest thing to "asking the teacher" for help that I can get. They offer a method of reporting incorrect answers, which I happily do, but no way of checking back to see if the feedback was accepted and corrected. Also the books that claim they are fully solved are anything but. Manage expectations.
If something is not solved/explained as it should, we are very sorry, and we would love to correct this. Would you be able to send us a little more details about the tasks you believe are not solved/explained correctly to Be sure to include a screenshot!


It was excellent at deciphering my near unintelligible handwriting, showed the steps, and has a great user interface. Only thing is you shouldn't use it on its own as some if the ways they get answers are on the complex side and if you are here that's probs too much, best used as a supplement to check work and give you hints.


Omg I'm a student and this app is the only thing keeping me sane, I'm so grateful for the reduced amount of ads, the help with calculator symbol ranges, the problem solving picturesque, and I cannot thank the people who made this enough!! It is so amazing using this and I hope you make no alterations because the app is perfect as it is. It has my Algebra math book on the app and provides detailed answers for FREE! I have not gotten the paid version and am perfectly content with the normal one.


I was pleasantly surprised by this app. Almost everything on the playstore, be it game or tool, is much harder to work with than it seems or just floods you with ads. And if not those 2, it costs money up front. but this free app is actually really useful. It rarely has trouble solving problems I see, and even shows the steps to solving them if you happen to care about that. And in all that time, I haven't seen any ads. They're probably on something I haven't used yet. Overall, really good. Ez 5


Like Every other promising app in this marketplace, money will always catch up. It's understandable to add some form of monetization. Creating tools isn't free, especially one as in depth as this one. If only they didn't take such a great feature and throw it behind a paywall. Take turning an improper fraction into a mixed number for example. It's only available in the animated "plus" version. I like this app, but frustrated now I have to pay monthly for what used to be a free usefull tool.
Hi, sorry for any confusion. The core features (equations & expressions solutions) are still free of charge, while AI tutorials, contextual hints, and word problem solutions do come at a fee. If you drop us an email at with a screenshot of the problem you tried to solve, we'd be happy to check what went wrong. Cheers!


Contains a great and useful calculator. Is good at explaining the math problems and has answers for my school textbook. Some actions are restricted because of the premium purchase but it doesn't get in the way too much. Is easy to use and adjust the size of the picture and see how they solve the problems.


I LOVE this app! I have always struggled with math since I was little and this has quite literally saved me from failing all my math classes It has the camera that scans your problem and almost always gives you an answer that is correct. The only thing that I think should improve is the step by step problem explaining. I saw a bunch of reviews that said that they used to be completely free. Although this app already makes my life a little easier, it would be even better if they were still free
Hi, the core features (like equations with step-by-step solutions) are free of charge. But as we grow and add more advanced features (AI tutorials, contextual hints, word problem solutions), we were bound to introduce a fee. We hope for your understanding in this instance. Drop us a line at if you have more questions. Cheers!


They responded to someone else's review just 10 days ago stating that the core features like explaining the steps to a solution are still free. This is not true, the explanation to how problems are solved is not free at all anymore. I had this app for a few years and used it a handful of times. It was extremely useful, until they stopped giving the steps to the solutions for free. Without that it's nothing more than a fancy calculator.
Thank you for your feedback. All of the functions that now require a subscription are either new to the app or improvements of the old features (ex. AI tutorials, contextual hints, word problem solutions, explain how). Our step-by-step solutions and equations are still free. If you have any other concerns please contact us on


For a calculator that uses the camera, its definitely beyond its game. Being able to explain through the steps helps people understand what and how an problem can be solved. For general purpose I think it's pretty reliable. It also has a built in calculator and if you need to change something in the problem you just scanned using the camera, you can fix/edit it with its edit problem feature. I'd say I love having it and it doesn't take too much space. Nice👍


This app is really great! I've got a lot of school work done using it and now have an A++ in my math class :) I also always make sure to read the explanation, because whenever I don't understand how to figure it out the explanation is really helpful. I would add a feature to solve word problems however, as I noticed it lacks that skill. As well as ability to take more than one photo. I had a really long problem the other day and a tool to take multiple photos would have been great! 4/5 :)
Hi Anna, thank you so much for your review & valuable feedback. I would like to offer you to join our pool of users for future media opportunities (we often get offers from media for interviews with our users, who find our app helpful). If you're interested, drop us a line at, we'd appreciate it if you agreed to testify!


2 years in and I adore this app. I hate apps that only give you answers, but no work to get to them. If they do, then you have to pay. It incentivizes students to cheat rather than learn. I want to actually learn how to solve the problems, so this app has been such great help in College level Calc 1&2. Only issues is sometimes, the answers are not simplified all the way. Also it's unnecessary to turn every single decimal value into a fraction. It's just makes it harder to follow the steps.

I'm an adjunct instructor in a community college. I teach courses in electronics, automation, and industrial engineering. So, yeah, a bit of math involved. A student brought Photomath to my attention several years ago. I was a little skeptical of how well it would be able to recognize various equations, etc., especially handwritten problems. So I installed the app and gave it a try. I was immediately impressed by the optical OCR and the way solutions were presented. It's outstanding.


Best app for someone who struggles with math. The break downs of how to solve a problem are done in a way that even the person who just doesn't understand, will finally understand. Definitely worth the paid version if you're a student. The app explains things better than the textbooks and even the teachers, in my experience! Can't rave enough. Download it, it's brilliant.


It is very convenient in doing math homework; yet, at the same time, there exist slight inconveniences in the design update, such as the instant problem solving. Before, you had to press a button, and it would scan the problem. You did it when you were ready; now, it immediately solves, scanning other problema on the page and messing up my answer that I need when I turn the phone away.


This app really is incredible. Works great, no ads, and completely free. Using this in a science class environment, it would be cool if maybe it had some formulas and constants built in, as an add-on, or even the ability to save them myself. Regardless, this is definitely now on my list of apps that get installed right at the start on a new phone. Thanks a lot for this one...


Amazing! Went above and way beyond my expectations! Rarely messes up and if it gets numbers wrong, you can go in and edit it with the smart calculator. Amazing sight. It can read the question in poor lighting, you don't even have to have perfectly steady hands to scan the problem, they can be wobbly and out of control! Lol! Amazing app! Genius! Props to the developers and anyone involved with this app. One of the best apps out there! Get it now!
