DenyCalls – Call Blocker for Unknown and Unwanted Calls
Only trusted people can call.
DenyCalls lets you approve the contacts who may reach you. With protection active, unapproved incoming callers can be blocked without relying on a global spam list.
Only trusted people can call
Traditional caller-ID apps try to identify suspicious numbers. DenyCalls takes a different approach: you decide who is approved. Trusted contacts ring normally, while calls from unapproved numbers can be blocked when protection is active.
