WhosCall is a call filtering app for iPhone and Android.
The app helps you identify background information of unknown calls in seconds through internet searching and community reporting! Whether it's random advertisements, annoying telemarketers, or malicious scammers, you are able to know who is calling you at a glance. With missed calls, you can also query the caller's information before deciding whether or not you want to call back.
