How to Choose Calculator Apps

Calculator apps have key similarities, but you should look into the different types, what they can calculate, and other features. By going through this buying guide, you can figure out what calculator apps offer, so you can pick one to help you with your daily needs!

1

Choose Between Basic and Scientific Calculators

Many calculators will either stick to basic math or offer scientific calculations, so you should use this section to figure out which type of calculator you need.

Basic Calculators for Everyday Situations

Basic Calculators for Everyday Situations
Some calculators just include the four basic forms of math: addition, subtraction, multiplication, and division. If you need a simple calculator for daily use, you can stick with a basic calculator.

Basic calculators are easier to use since you only have a few forms of math along with some convenient buttons. They also keep everything on a single screen, so you can see everything the app has to offer.


Many times, these basic calculators will include extra features that make them more useful, such as unit conversion or automatically calculating percentages. However, basic calculators won't help you much with advanced math in high school and college classes, such as trigonometry or geometry.

Scientific Calculators for Advanced Math

Scientific Calculators for Advanced Math

If you have a math class or work in a profession that requires advanced math, you could use a scientific calculator app. Scientific calculators will simplify advanced calculations, including sine, cosine, tangent, and the inverse versions of those three.


They also do basic math, so you won't have to switch between basic and scientific calculator apps. However, they are more difficult to use since you have more buttons and screens to deal with.

2

Check the Additional Calculations Included

Some calculators will include additional calculations like percentages and sales tax, so let's see what they can do in your daily life.

Calculators for Shopping and Figuring the Tip

Calculators for Shopping and Figuring the Tip

Since sales tax varies between states, you may want to use a calculator that will tackle it for you. Stores tell you the price without the sales tax, so you can find out the exact price using a calculator with this option. You can add up the costs for everything you plan to buy and use the sales tax calculator to see if you have enough money.


They can also help you if you want to calculate how much you should pay someone for a tip after you go to a restaurant. If you need to budget and want an easy way to see how much your groceries will cost, a sales tax calculator can help you.

Percentages to Simplify Math

Percentages to Simplify Math

Some calculators will include percentage buttons to calculate them for you. Percentage buttons will immediately turn the percentage into the correct decimal, so you won’t have to do the math. This can also help you avoid mistakes since you won't have to do as much math to find out the percentage.


You can calculate percentages with division and multiplication, so some people may find the button pointless. But if you want to cut down on steps or avoid making mistakes while calculating percentages, you may want a calculator with this button. 

Unit Converters Help in the Kitchen and More

Unit Converters Help in the Kitchen and More

Some calculators will add unit converters to help you with quick calculations. These can include unit converters for miles, pounds, kilograms, and many other units of measurement.


If you get a calculator with a unit converter, you won’t have to switch between apps when you need to make conversions. These converters can be great for cooking since you can find out how many ounces are in a liter along with other information.


If you find yourself working with unit conversion for work or as you do other tasks, this might be a key feature for you.

3

See What Other Features You Want

There are some useful features included with calculator apps, such as making graphs, getting instant results, and seeing calculation histories. Make sure to check these features out, so you can see what they will offer you!

Graphing for Math Class

Graphing for Math Class

A few calculators will let you create graphs by inputting the data points into the calculator. Graphing calculators can help you understand trigonometry and similar math courses by letting you see how things look on a graph.


The graph gives you a visual, so you can tell if you made any mistakes since it won't look right or connect the way it should if you messed up. However, the graphs can be difficult to use, which could frustrate some people. If you like visuals or need a graphing calculator for your class, you should find an app with this function.

Calculation History Allows You to Reference and Record

Calculation History Allows You to Reference and Record

Many apps will include calculation history or tape, like from an adding machine, to give you quick access to anything you typed into your calculator. You may do a calculation and forget what answer you got, so you can go back to it and find out with this feature.


You can also tap on those previous calculations to bring them up, so it can help you save time if you want to add more numbers to it. Depending on the app you use, it may only save so many calculations, so they could disappear after a while.


If you tend to forget your past calculations, you can use this feature to save some time. It's also essential if you use your calculator tape to keep track of things like your sales or purchases.

Instant Results for Convenience

Instant Results for Convenience

Some calculators will automatically calculate the equations as you go. For example, if you add two numbers, it will show you the result before you press enter. If you want to make your calculations more convenient and faster, you should get one with instant results.


Since you can see the results as you type in the equation, you can use that to see if you put in the wrong numbers. However, some people may find it distracting if they have to type in a long equation and the current answer keeps appearing at the bottom.
