TruCaller is an application that makes it possible to know who is calling you, even if that person is not in your phone book. The video above from an earlier version shows it in action. The software supports 21 countries and can take around 2-3 rings to look up the information about a caller from national databases over 3G or WIFI.
The latest version, 1.20, adds many new features including:
– Update phonebook: Update all your contacts with missing information such as city, zip code, address
– Twitter integration: Tweet your calls!
– Google maps integration
– Completely rewritten code
– All new improved user interface.
