15 Best Free Calculator Apps for iOS: Fast, Simple, and Convenient

We use apps nowadays for almost anything. Tracking our movements through the day, reminding us to drink water, and to see how much protein we’ve consumed (if you are a fitness freak). There is literally an app for anything. Of course, we all sometimes need help with mathematics. Opening a calculator app to see if 2+2 is 4., just to be sure.

Now, mathematics is a pretty broad field, and it is not just calculation. That’s why we have decided to make the list of the 15. best free calculation apps for iOs.  Buckle up. The list is long but worth it.

1. WolframAlpha

WolframAlpha icon and name

The first spot on our list goes to WolframAlpha. It is on the first spot for a reason, and that’s because it shows you the formula details, explanations on how it came up with the result, and graphic representations.  It shows every single detail of the process – it is like having a math tutor for free.

This app is an expert in math, calculations, numbers, and statistics + 29 other disciplines as well.  The only downside to this perfect app is that you need to have an internet connection to use it. But, that’s not really a problem is it, since you can get Wi-Fi on every corner.

2. Photomath

Next on our list is the amazing Photomath (I wish this existed in my high school days). This little helper turns your camera into a calculator or, to be more precise, a scanner.  You just point the camera towards the problem that is bothering you (a mathematical problem, of course), and it shows you the result. Just like the app before, this one also provides you with a step-by-step breakdown of the entire calculation.

Photomath also provides alternative answers, editing the scanned equation, and a brand new graphic mode. With this little fellow on your phone, you can handle trigonometry, equations, and inequalities, as well as systems of equations. And all that in no time at all.
