There is a lot of software in the web, but, there is also software on a computer (on a ‘desktop’); like for example WinWord (or LibreOffice Word) is only on your computer, not on the web.
Of course, if the program runs on your computer, you do not have to be connected to the internet. Also, a software on your computer is easy to install, and easy to use.
For software supporting you, and you do not need to work together with other people, a ‘desktop application’ is a good choice.
Please contact as and let us know your needs! We are glad to support you with desktop applications.
