Developed by Modoohut, ExDialer PRO Key is not exactly an app - but more of a key that will activate another platform so that it will be upgraded to PRO. You will not find a launcher icon for this, in particular - nor will you be greeted with its own user interface. Purchasing this will activate all of the amazing features of ExDialer - which is a program that manages your contacts, phone calls, dialer, the contact search command, and more. It also simplifies your access to certain contacts, and customizes your dialer.
