PrivacyStar now has a free Android app that’s suppose to work as a true caller ID and call blocker. Android smartphones may have a reliable phone app that stores a long list of contacts, but don’t confuse that for a true caller ID. At times when a caller’s number isn’t saved on the phone, the caller ID will fill the information gap by telling you who’s calling regardless of your phonebook’s contents.
According to Technologizer, the app’s call blocker feature costs $2.99 monthly after the seven day trial period. Paying the monthly fee means having access to a web portal where the user can manage blocked callers and review call logs.
