Whoscall- Caller ID&Block

the second ring, "Who's calling?" carries out research and suggests the number of the caller, and if available, their information and address on the map.
BLACKLIST
"Who's calling?" enables you to block unwanted calls, call centres, stalkers and other undesirables.
Create a black list with all the blocked numbers.
You can add numbers to the blacklist:
- yourself
- when you receive a call
- from the caller list
- from the address book
You can block anonymous callers
