The best calculator apps for Android

Stylish Calculator CALCU

Price: Free / In-app purchases ($1.99 – $24.99 per item)

CALCU is one of the most popular calculator apps for Android. It features all of the basics. Some other features include a calculation history, memory keys, various customization features, themes, and gesture controls. It’s not a full scientific calculator, but it does have enough functions to go beyond what you normally find in basic calculators. The free version of the app contains advertising. It’s a good competitor for the stock calculator app that comes on most devices.


Price: Free / In-app purchases ($2.99 – $24.99 per item)

ClevCalc is kind of an all-in-one solution for calculator apps. It has a general-use calculator with your usual operators. It also contains simple trigonometric and logarithmic functions. However, the thing that sets this calculator apart is all of the other stuff it can do. Some of its additional functionalities include currency conversion, unit conversion, a unit price calculator, and a variety of other tools. Another example is a discount calculator. You enter in the price and the percentage off, and the app will tell you its new retail price. We encourage you to check out the Play Store description for the full list because it is rather lengthy.

Desmos Graphing Calculator

Digitalchemy is a developer on Google Play. They have three total calculator apps. The first is Calculator Plus. It’s a basic calculator that does everything you’d expect a calculator app to do. The second is the Fraction Calculator. Its main focus is fractions. It lets you make calculations using them without breaking them down into decimal format. This is excellent for early mathematics, especially for kids. The final one is the Artful Calculator. It’s essentially just Calculator Plus but with more artsy themes. You can go with any one of them, but we listed it here for its fractions calculator because you don’t see a good one of those every day.

There have been a few bugs reported with a few of the modes, but the vast majority of them work perfectly. Anybody who needs help with calculating their finances should check this out. It’s completely free with no in-app purchases. It does have ads, though.

HiEdu Scientific Calculator

It also works with more advanced stuff like logarithms and other such things. The UI is clean and simple, and the app includes over 1,000 math formulas. You can do basically whatever you need short of graphing, and there are other calculators for that. That may upset some people, but it’s still factually accurate. The pro version runs for $1.49.

HiPER Scientific Calculator

HiPER Scientific Calculator is one of the best calculator apps for android

MyScript Calculator 2 is one of the more entertaining calculator apps for Android. It lets you write out your equation. The app uses OCR to translate it into text format and then helps you solve the problem. It’s easy to use, fun for kids and adults, and there’s a certain satisfaction in writing out the equation yourself. The app supports basic operations, powers, roots, exponentials, some trigonometry, logarithms, constants, and more. Thus, it’s usually good enough through high school and up through the collegiate levels for most people. However, those dabbling in super complicated math will max this app out fairly quickly.

RealCalc is a mainstay in this space and one of the best overall calculator apps. It’s not much to look at, but it includes a ton of functionality. Some of its features include trig functions, result history, percentage support, unit conversions, multi-window support, and more.

Your phone’s calculator

Price: Free

Here’s the thing, folks. Unless you’re a student, a mathematician, or an accountant, you probably don’t need a super complicated calculator app. A lot of people only need these things to determine how much to tip at a restaurant or count down their cash drawers at the end of the night at work. For that, the calculator your phone already has is perfectly capable of doing the job. We only recommend the other nine apps on this list if your built-in calculator is really bad. Don’t feel the need to download a third-party app just for the sake of it. For those interested, Google Calculator is linked at the button below if you want the most basic calculator that just works.
