Kudos to whosoever created this app. This app is ultimate requirement of almost everyone. It automatically detects the persons who is calling you, if the contact isn't saved already. It provides you with the name and location of the caller, so you may know who is trying to reach for you. I got so many calls from unknown numbers and because of this app I can know in advance the person who is calling me and if I want to stop someone from bothering me I can even block him /her. My phone doesn't allow me to block someone so I use truecaller to block contact from bothering me. The app works fine. It also blocks telemarketing calls automatically and even let you know if any number that has called you is ever reported as spam or not.
I think it's a must for everyone go and give it a chance.
