I need to know if it is possible to replace the iOS Contacts app with a custom app that handles both inbound and outbound calls and texts?
By which I mean - when a call or text is received, the user’s name displays in the call, and the phone number displays in the Contacts app. I want to replace the Contacts app there with one of my own making.
Recent calls would not display a phone number from the Contacts app or its replacement, only the caller’s name or “Unknown”
Is this possible?
