Scribble Calc

Scribble Calc is a Metro application you can use to perform mathematical operations using standard functions, such as addition, subtraction, multiplication and division.

Compared to other similar Metro calculators, this one has a whiteboard you can use to add notes by scribbling with your mouse cursor or finger on touch-supported devices.

Wrapped in a Modern UI, the tool can be installed from the Windows Store on computers running Windows 8, 8.1 and 10. It doesn't need Internet access to work, so you can use it to perform calculations even when you're offline.

As far as the interface is concerned, Scribble Calc has a large window with a white background, where the calculator is displayed on the lower-left side.

Unfortunately, the keyboard isn't supported, so you can only send commands by clicking the corresponding buttons. Also, the current number disappears as soon as you pick an operation, so full expressions are not displayed.

It's possible to perform multiplication (x), subtraction (-), addition (+) and division (/), use positive and negative numbers (+/-), calculate percent values (%), use the decimal point (.) as well as clear the entry (CE).

To doodle the whiteboard, simply click and drag with your mouse or tap and drag with your finger. If you want to reset the whiteboard, click the "Clear Notes" button on the bottom.

Aside from the fact that you can take a snapshot of the calculator and send it to one of your installed Modern UI programs, whether you want to save the image to file or share it with a friend, there are no other settings implemented by the developer.

Scribble Calc doesn't feature advanced functions, such as sine, cosine, tangent, cotangent, logarithm, natural logarithm, pi or e constants. Nevertheless, it offers a clear-cut interface for performing basic calculations, along with a whiteboard which you can scribble to add various notes.
