Our math teachers warned us that we won’t have a calculator wherever we go. But now we have smartphones wherever we are, with access to hundreds of calculator apps.

Since there are so many options out there, finding the right one for your needs can be difficult. Today we are going to break down The best free calculators for Android.

The Top 9 Best Free Online Calculators Are:

1. Calculator (from Google)

This is your easiest and safest bet. Google offers a simple yet well-designed app that will do basic math problems, but nothing more. It measures in real-time, therefore you don’t even have to stretch for the matches button.

You can get some more advanced features by swiping to the right, but this is still a fairly limited set. The only important feature is that you can tap at the top of the screen to open a three-dot menu that lets you change decimals to fractions – and that’s it. There is no history or graphics.

It’s completely free and has no ads though. This way it gets the job done (unless you’re trying to live without Google).

2. Calculator-app

If Google Calculator is too easy for you, try Calculator-app. This app has both an easy and architectural style. It supports a wide range of features, history of everything you’ve calculated, and it can even create graphs.

One of the nice little things is the highly removable buttons. Swipe up on the button to activate the option at the top and swipe down to activate the option at the bottom. It is also customizable with multiple theme options. Along with the home screen widget, it includes a floating window mode.

This app contains ads, but they only appear on side pages, such as history, and not on the main calculations page.

3. ClevCalc

ClevCalc is a bunch of calculators in one. Not only does it have the basics similar to a money and unit converter, but it also has everything from a fuel cost calculator to an ovulation calculator.

You can choose from several themes inspired by Material Design. Although there are ads in the app, you can remove them using an in-app purchase.

4. Calculator (from TricolorCat)

Here’s an option that is simply called Calculator. This one is best for those who are very picky about their keyboard.

Because it has three distinct layout styles: colours, smart and Comfort device.

It also has many different color options and the ability to add or remove memory buttons. In addition, you can change how decimal places are displayed (1.5 or 1.5) and view history by swiping down from the top. It’s very simple, yet more customizable than most mainstream calculator apps.

There are banner ads at the bottom of the app, but you can buy the Pro version to remove it.

5. Scientific calculator CalcTastic

This application is for those who need more possibilities for scientific calculations. It also has a basic calculator but focuses on the scientific part. You can work on difficult problems that you like, but they cannot Draw anything.

6. Scientific calculator RealCalc

Another good scientific calculator is the popular RealCalc. It’s designed to look like the traditional Moveable scientific calculators you used in school.

RealCalc has all the official Correct pieces you need. It also supports history, memory, unit conversions, and constants. Double, octal, and hexadecimal calculations also work great.

The free variant offers many valuable characteristics that may be sufficient for your purposes. If you need additional features such as fractions, degrees/minutes/seconds, custom conversions and constants, landscape mode and a 12-digit display, you can purchase RealCalc Plus.

It has quick little swipe animations, such as swiping down to reveal a story or swiping up to Disclose more science buttons. There is a banner ad at the top that can be removed by purchasing in-app for $ 2.

8. One calculator

One Calculator has a stylish look including smooth transitions and animations with beautiful colors. It also has a matrix calculator, converter, and graphics device.

Sadly, each theme costs $ 1.49, but that’s the price to pay for an ad-free calculator that covers all the basics: basic, scientific, and graphical. It’s so spontaneous and liquid that you’ll like it right away.

9. Graphic calculator Desmos
