One of the main reason of having Truecaller is, any user can block the unwanted calls. Truecaller lets you search beyond your phonebook, identify unknown incoming calls, block calls you don’t want to receive.
You can know who is calling if you don’t have their number in your phonebook. You can also block unwanted calls from spam callers and telemarketers. If you want to search for any number in the world to see who it belongs to you can now copy a number anywhere and Truecaller will notify you who it belongs to.
Truecaller is developed by True Software Scandivania, a private company in Sweden. Truecaller was founded by Alan Mamedi and Nami Zarringhalam in 2009.
Firstly it was developed and launched for Symbian based and windows based mobiles and later for Andrid and iOS and Blackberry as well.
You can install the app from playstore.
