UtilityApp

UtilityApp is a Java-based application that integrates a basic math calculator and two converters for time and currency. It contains standard options for all types of all users and comes in handy especially when you don't have a working Internet connection to carry out these easy tasks online.

The entire program's packed in an executable .jar file that can be saved to a preferred directory on the disk or on a USB flash drive to seamlessly launch it on any PC with Java.

It doesn't make any changes to the system registry or create files on the disk without permission. In order to remove it, you simply have to delete this file.

The interface is user-friendly, represented by a standard window split into three panes for separately converting time and currency, as well as performing calculations.

It's possible to consult a calendar and pick any date for the conversion, specify the time, as well as pick the time zone from a drop-down menu. When it comes to the currency, you can enter an amount and choose the source and output. The calculator is pretty basic, since all you have to do is click on numbers, make additions, subtractions, multiplications or divisions, as well as view results in the bottom part of the screen.

There are no other notable options provided by this tool. For example, it doesn't implement buttons for printing information, copying it to the Clipboard, or exporting it to file for closer examination.

It didn't put a strain on the computer's performance in our tests, thanks to the fact that it needed a low amount of CPU and RAM to work properly. It remained stable throughout our runtime, without causing the operating system to hang, crash or indicate errors.

To wrap it up, UtilityApp may not have a particularly rich set of options and customization preferences, but it offers a straightforward solution for performing calculations as well as time and currency conversions when you don't have an active Internet connection.
