I have almost 40 years of experience with data, and with it follows a trained look for rating and testing software and apps. Quality control of compatibility, functionality (UX), and user interface (UI). Does the program or app work as expected? Is it good English or English language? Does the data terms follow the plain Norwegian or international standard? If you need an external user to check their program, then get in touch! I work daily on Windows and Android but can occasionally switch to other platforms.
