1. 1/5The other reviews aren't kidding. Don't waste your time with this app.

   Let's get straight to the point: this app is useless without spending $20 something every 3 months. Don't take my word for it: there are countless other reviews mentioning this as well. When you first open the app, guess what? It immediately wants you to allow camera access (makes sense) and notifications (which doesn't make sense, why would a math app need to spam my notifications?), then it asks you to sign up for their subscription. I, like most people, ignored it and clicked the X. The next thing I did was scan a problem. Guess what? You can't get the answer or steps without paying! You read that correctly, you have to buy their subscription to even get access to the answer! What's the point of a calculator if it doesn't even give you the answer?? Imagine if your physical calculator (or calculator app on your phone) said something like "Please pay $9.99 to get access to the answer." This is basically what this app is. Yes, there is a free trial, but you gotta remember to cancel it immediately so it doesn't charge your card. It's just not worth it. Don't waste your time. TL;DR, app wants money to solve math questions, which defeats the whole point of it being free.

2. 1/5Don’t waste your time on this lousy “calculator”

   I was looking for a better calculator that actually shows the steps of a problem without having to spend money. I used this app literally for 5 minutes (I’m not kidding) to put in one problem. Guess what happens, they didn’t even show me the answer. It was blurred. That’s right, the answer was blurred. Not the steps, the ANSWER. Maybe because it was a trigonometry equation (studying for final exam) so I put in a different equation, a simple algebra equation. NOT EVEN A SIMPLE EQUATION WITH ONE VARIABLE HAD AN ANSWER. WHAT THE HECKING HECK. The point of a calculator is to give you the answer, even a calculator from dollar tree can give me an answer. But this FREE app won’t even give you the ANSWER. I don’t mind not having the equation worked out for me, but cmon give me the answer. This app is basically a calculator that has no point. What kind of calculator doesn’t give you the answer? I still use photomath because it still shows me the process without having to spend money. Although to understand the process as to WHY, that’s when it costs money. But don’t waste your time on this app. It’s pointless.

3. 1/5They only want money!

   I got this app because I had a frustrating problem and needing help. All the reviews said awful things, and I thought they were over exaggerating. THEY WERE NOT! the first thing that happened after I downloaded the app was it asked me for money. 20 something dollars a month. That’s insane. I ignored it and clicked the x. After I clicked my picture, guess what happened, they asked again for money!! Good people and apps who want to help should be for free. I truly recommend to anyone who’s reading this, find any other app to help, or ask a non crazy adult or friend. I couldn’t even get into it, but if you are willing to pay that, I hope it’s better then the outside of it. I don’t know if there are ads, but that would make it over the top awful. Thank you for reading this and I hope my opinion helped your decision.

4. 1/5This app is horrible

   Had it it for a week I was hoping to get an app that I could use for online school and when I got this app I didn’t look at the ratings but I really wish I looked at the ratings I got this app and it seemed pretty simple you just snap a picture and give you the answer when I snap a picture and then it says sorry we can’t solve this math problem but will tell you later I did this multiple times and it still didn’t work and I tried it with multiple other problems and it didn’t help me whatsoever and the app would repeatedly just take me out of it and not let me back and I would click on it multiple times but it still didn’t let me in and I clicked on my other apps on my phone and they all let me in so it’s definitely something wrong with the stupid app

5. 1/5If I could give it 0 stars I would

   So this is a terrible math solving app. To make Make it so you can be able to actually access what’s the answer in the solution is you have to pay for a trial. That’s the stupidest thing ever if you really want to think about getting an app think about getting an app that you don’t have to pay worth money in US dollar make it so you can be able to actually access what’s the answer in the solution is you have to pay for a trial. That’s the stupidest thing ever if you really want to think about getting an app think about getting an app that you don’t have to pay worth money and US dollars. If you want an app that you don’t have to pay USD dollars for bingo search up quick and fast. That’s the app that you don’t got to pay for sweetie..
