10 Best Calculator Apps for Android to Fulfill Your Math Needs

Last Updated: September 27, 2016

A calculator app is one of the most basic yet important apps on your phone. You need to deal with calculations everyday and a calculator app allows you to use your smartphone for all the calculations on the go. However, the default calculator app in most Android smartphones is fairly limited and lacks a  bit when it comes to solving complex equations. If you need a scientific calculator that can help you with all types of calculations and math problems, you will have to go for a third-party calculator app.

Fortunately, there are many cool calculator apps available for Android that offer reliable features and the power to solve complex problems. We bring you a list of the 10 best calculator apps for Android to help you with all your calculations:

1. Calculator Plus

Calculator Plus has an interface very similar to a handheld digital calculator. It can do all the basic functions you need for quick calculations. In addition, it offers a memory feature, which is found on most digital calculators to store and recall calculations from the past. If you need the scientific calculator, you will have to download a companion app by going to the main menu of Calculator Plus.


The scientific calculator offers everything you would expect from a scientific calculator. It has multiple modes for different uses, including Complex, Matrix, Equation and Graph mode. Furthermore, Calculator Plus keeps a complete record of your calculations and never forgets them even if you close the app. You can see the complete history along with how the equation was solved.

2. MyScript Calculator

The biggest problem we face when we try to solve math equations with a calculator app is entering the data using the on-screen buttons. We are used to writing and solving equations on a paper, so a switch to on-screen buttons makes things a little harder; unless you have the MyScript Calculator app. The app lets you use your hand or a stylus pen to enter equations, after which it’s converted into a digital equation.


It solves equations in real-time and also fills-in any gaps you may have left while drawing (quite smartly, I must say). I had no problem entering equations using my finger, but I suppose the app will work best with a stylus and on larger screens, like a tablet. It supports all common operations such as, constants, brackets, exponentials, trigonometry and logarithms. If you are not good with digital calculators, give MyScript Calculator a shot.

3. Calculator by Google

The Google Calculator app is the default calculator app on most stock Android smartphones, so chances are, you are already using it. However, if you are not, you should consider getting it. It’s a basic calculator that is perfect for everyday use but what makes it a good pick is its extremely simple design and smooth working. You can do basic math calculations like multiplication, subtraction and division, etc., and it can also handle a few scientific operations like logarithm, trigonometry, constants and exponentials.


All the calculations are made in real-time and the Material Design UI certainly makes up for a great experience. Best of all, it works flawlessly with Android Wear to let you do calculations right from your smartwatch.

4. Calculator ++

Calculator ++ is another smartly designed calculator app for Android, which has an interface similar to Google Calculator. It has two basic layouts, Standard and Engineer. Standard mode offers basic calculation tools along with multi digit support, one-tap copy/paste and other basic math tools, such as constants. In the Engineer mode, you can use advanced tools to solve problems like logarithms, trigonometry, powers etc.


Calculator ++ offers automatic solutions, so that you can quickly enter values and get results. It even includes gestures, which make the experience a breeze. Furthermore, you can also change calculator themes and use the homescreen widget for quick access. One cool feature I really liked, is its floating window feature, which lets you use the app on top of other apps, to do calculations on the go.
