I have been using the same base converter for years. Then it announced that it would not work with the new IOS. So, I went looking for a new one. Glad I found this one. The old one would allow you to enter a number in the selected base and then you selected an alternate base to display. This new converter displays all four bases at the same time. A nice feature is, when one enters the desired number, in its selected base, illegal keys for the base is locked out.
