TrueCaller free download
With this app you will always know who is calling from an unknown number. It is also possible to determine the initials of a person by his phone number.
The Truecaller database is replenished by the users themselves. When you install the application, it scans the phone book, searches for matches and makes contact information in its database, which is accessible to all users.
In the database, each number has its own rating, which depends on the frequency of matches. For example, the highest rating in public services or banking organizations. However, the program is rapidly developing in the domestic market, and you can already use its functionality and participate in the development of the program.
