The first computer ever made didn’t have many features. However, one of the few features it did have was the ability to calculate. It’s no wonder then why the calculator became one of the first computers many of us ever owned.
Smartphones have replaced many devices we once used, and the calculator is one of them. Almost every Android phone comes with a pre-installed calculator app, which is quite sufficient for simple mathematical operations. If that app isn’t enough for you, check out our list of the top 3 best free Android calculator apps.
Google Calculator is a free calculator app available for Android. This is one of the simpler applications of its kind, but it still has enough options to satisfy the needs of most users.
In addition to the basic math functions such as addition, subtraction, multiplication, and division, Google Calculator also includes options for trigonometry, logarithmic functions, calculating roots, and more. However, despite this, the application does not contain functions for advanced mathematical operations, which will be needed by those who need a quality scientific calculator.
Since Google Calculator is a general-purpose calculator, the lack of advanced features is not a minus, quite the opposite! The user interface is nice and easy to use, and all the options are easily accessible. In addition to this, the app is completely free and has no ads at all. This is the best app for most users.
Calculator ++ is a free calculator app available for Android. If you need a calculator for scientific work or for college, this might be the right application for you. First of all, we have to praise the user interface which, in addition to looking good, is extremely easy to use, which is an enviable achievement when you consider the large number of options it contains. Also, the application includes the ability to change the theme, so you can adjust the appearance to your taste.
Calculator ++ has two modes, Simple and Engineer. As you can guess, Simple mode will allow you to perform basic math operations, while Engineer mode offers advanced options. Engineer mode, in addition to options for calculating roots, trigonometry, exponentiation, and more, also includes options for calculating equations, solving mathematical problems, and even includes an option for drawing graphs. All calculations are stored in the history, from where they are easily accessible.
The biggest drawback of the Calculator ++ application is the fact that it contains advertisements in the free version. Ads are shown only on less important pages, such as the history page so that they are not so annoying and do not interfere too much. However, we would rather not have them at all.
Desmos Graphing Calculator
Desmos Graphing Calculator features a clean and streamlined user interface that is extremely easy to navigate. It has all the features we expect from a quality scientific calculator, but as the name suggests, it focuses on graphing.
In addition to creating a graph, with Desmos Graphing Calculator you can examine the graph in detail, track changes by changing values in the equation, see the maxima and minima by simply touching the graph, and much more. Honestly, you’ll be hard-pressed to find a better free graphing calculator than this one.
The free version of Desmos Graphing Calculator is ad-free, which we really liked. Unfortunately, for certain options, you will have to pay for the premium version of the app.
