TrueCaller is equipped with some useful functions, such as name display, reverse number lookup, location and number of the caller, and a social website feature that notifies followers when the user is on the phone. What this application is most coveted for, however, is its ability to support a list of callers the user blocks in order to prevent unwanted calls, whether from salespeople or individuals with whom the user no longer wants to speak.
In addition, TrueCaller also notifies the user of spam calls that are being received and tagged by other users who utilize the application’s database. This particular feature helpfully allows a TrueCaller user to block spam before they even receive it.
