Smartphones and tablets make handy calculators. They all come with calculator apps, but sometimes you need to evaluate an equation, and you'd like to see the entire equation and share it. Sure, you can use a pushbutton calculator app, but writing your own equations is much more fun. MyScript Calculator is a handy and free app I use on both an iPhone and iPad.
If you prefer to write your own equations with your finger, then download the MyScript calculator app for iOS devices from the app store. There's also an Android version.
To appreciate this app, you need to see it in action. Start with the video below, and then take a look at the screen images in the slideshow below.
MyScript Calculator also evaluates trigonometric functions, It can raise a number to any power, and it has built-in values such as π. That's great for some engineering calculations. See the slideshow below for a few examples. In some cases, you don't always get what you want until you learn how to write your equations properly.
In the slides below, you can get a feel for what it can and can't do. As you'll in slide 3, MyScript Calculator can evaluate equations that include exponents, though getting them right may take some practice. That can be a little frustrating, but with practice, you can get the equations right. Fortunately, you can step back through your steps and retry them, but you'll have to weigh the time it takes versus using other calculators. Remember that the app is free. It also includes a video tutorial to get you started.
If you install and use MyScript calculator, tell us how you use it. If you tried and uninstalled it, tell us why. Click the image below to open the slideshow.
MyScript Calculator can handle simple equations such as this one that converts 20°C to 68°F. Remember that MyScript a calculator, not an equation editor. You can't use variables.
