TrueCaller offers a form of Web-enabled caller ID for your Android phone, FOR FREE! It enables you to match phone numbers to names, addresses, social networks, and even pictures! The application automatically engages when you receive or place a call to a phone number that’s not already in your address book, searching online for identifying information connected with that number. Within seconds, TrueCaller displays public information associated with that phone number on the Web, such as the other party’s name, address, region, and country. If available, the display will even include the caller’s picture, and/or most recent status messages from Facebook or Linkedin. TrueCaller will flag known spam callers for you–and you can add to the spam caller list at the touch of a button, should you have the misfortune of discovering new ones. The enhanced search feature will return name of prepaid phone cards and unlisted phone numbers, as well.
