TrueCaller is a smartphone app that lets the user see who is calling when they call, even if the caller is not in the user’s address book. It gives you information about callers who are not in your address book, such as marketers and spam callers. It can also block unwanted calls so that you are not bothered by unnecessary rings. The app is gaining popularity among tens of millions of users. It is quite efficient in identifying and eventually blocking unwanted calls and matching names and numbers.

The app runs on Android, iOS, Windows Phone and BlackBerry 10. It requires an internet connection to work via wifi or mobile data. The interface is quite simple and intuitive. It doesn’t have a lot of features and it doesn’t need to because it does the few things it says it does, as we’ll see below.

When you install TrueCaller, you'll go through a short registration process that asks you to sign in using a Google account, a Facebook account, or a Microsoft account.

TrueCaller works primarily as a super powerful caller ID app. It tells you who is calling, who the caller is, and where they are from. You will no longer see things like “Anonymous” or “Private Number” on an incoming call. You will also be saved from annoying commercial calls or wet blanket calls.
