Intercept Phone Calls is a free Android application developed by Amalgam Apps under the Social & Communication category. The app provides a reliable way to block spam calls and manage phone contacts. When receiving a call from an unknown number, the application is activated and offers the possibility to search the internet for the number and check whether it is a reliable number.

The app comes with a feature that allows users to add the phone number to either the blacklist or whitelist. This means that users can reject or accept calls from the numbers added to the blacklist or whitelist respectively. In addition, users can add phone numbers to contacts and even edit or add comments to the phone numbers. The app also allows users to switch on and off protection and block calls from the blacklist, accept calls from whitelist, accept calls from contacts, and block calls from private numbers. Notifications are shown after blocking, and the ring is silenced when searching.
