Calculators are still important in today's world. We use them not only for everyday tasks, but also for more technical and specialized tasks. But nowadays, Calculators have become part of the tools of smartphones. Some are native, while others are powerful calculators that you can download in the app market. One of them is OpenCalc, one of the best scientific calculators available for Android.
In this post you will learn a little more about OpenCalc. We will analyze its design and usefulness, as well as its advantages and disadvantages. Let's get started.
OpenCalc Features
With OpenCalc you can quickly and easily do basic operations such as addition, multiplication, division and subtraction. In addition, it includes advanced functions such as square and cube roots, powers, logarithms, trigonometric functions and important mathematical constants.
Among the trigonometric functions There are sine (sin), cosine (cos) and tangent (tan) that can be calculated in both radians and degrees (DEG). Also included is the inverse function (INV) to find the arc whose trigonometric function is a given value.
Other advanced functions They are the natural logarithm (In) and base 10 logarithm (log), as well as the mathematical constant e (Euler number). All these tools make OpenCalc a calculator suitable for students who need to solve more complex expressions and equations.
App design
The app has a minimalist design and a very simple, intuitive and effective interface. This is very similar to the calculator that comes natively on most mobile phones. In terms of weight, it is only 2 megabytes for Android phones.
This modern and beautiful scientific calculator can be customized to meet your requirements. Has dark themes, one rather classic and the other amoled, in an intense black. The default theme that comes with the system is the light theme. It is a calculator that allows you to customize the theme to suit your phone and your needs.
It stands out because it is open source, It has no annoying ads and is very easy to download. It also does not have unnecessary permissions. It is available for Android and can be downloaded from the Play Store for Android. 5.0 or higher.
Advantages
Among the advantages that stand out from this application are:
- It is light, charges very quickly and The calculations are done very quickly.or also.
- It comes with a wide range of scientific functions to perform different calculations.
- It is free and open source.
- It has an intuitive interface.
- No unnecessary permissions.
- It does not have advertising. The developers placed a link to PayPal for donations. That is, the app is maintained through these donations without having to resort to annoying and invasive ads.
- It has a function to prevent the phone from sleeping when in sleep while the application is running.
- It has a large capacity to save in history the calculations that have been made.
- Has the scientist mode which can be placed in default mode.
- You can also customize radians instead of degrees.
- Portrait and landscape orientation.
- Quick setup tile.
A simple and beautiful calculator for Android.
Disadvantages
Some of the disadvantages of the app are some errors that users have noticed when using it:
- Calculation errors of the inverse function of the tangent (tan-1) for values ​​greater than 1, giving results outside the domain.
- In split screen view, the position of the buttons cannot be used, and basic arithmetic operations are missing.
- Automatic screen rotation is sometimes activated inappropriately when lifting the device, creating a frustrating experience for the user.
- The decimal point is not displayed properly in parentheses in numbers with many decimals. This makes readability difficult.
- Lack of TalkBack support for visually impaired users.
- Lack of support for advanced calculations of algebra, statistics and mathematics that do exist in other professional calculators.
- Poor performance and stability on older devices or devices with little RAM.
