Truecaller

Truecaller is the most popular application that allows you to find out who is calling from an unknown number. It can also block unwanted calls, completely protecting you from unnecessary calls. If the blocked subscriber tries to call you, he will hear a busy signal.

TrueCaller also allows you to search manually. Just enter the number and you will get the name attached to it, as well as some other information, for example, the name of the mobile operator. This is possible thanks to the huge database that contains information on billions of calls. For example, in India alone, the application employs 150 million people.

The app was originally developed for BlackBerry phones in 2009, by the Swedish company True Software Scandinavia AB, founded by Alan Mamedi and Nami Zarringhalam. From there, it quickly expanded to other platforms, including iOS and Android. And for 10 years now, the company has been collecting data on telephone numbers.

After installation, you will need to go through a quick registration through authorization using your Google, Facebook or Microsoft account. If you enable the “advanced search” option, Truecaller will look at your contact list and also add it to your database. In return, you will be able to find out how other users are recorded in the phone book.

CallApp allows you to identify unknown subscribers, block spam calls, record incoming and outgoing calls. At the same time, the identification of unknown numbers remains the main function, so it is not surprising that spam blocking does not work very well.

It is worth noting one more minus of CallApp - high energy consumption: when it is used, the smartphone’s battery is consumed faster than when working with Truecaller in the same conditions. Nevertheless, the application deserves a place in this list, since it copes well with its main task.

In addition to standard features, there is an “Incognito” mode with which you can hide the number of a specific subscriber, and it will not be displayed not only during an incoming call, but also in the call log. If suddenly, you have a person with whom you want to talk, but so that no one would know about it by taking your phone - this is what you need.

At the moment, the application has a base of about 20 million users. The Show Сaller interface is very similar to Truecaller, however, unlike the latter, it takes up much less space. Identification of subscribers is fast enough. Of the minuses, you can name only the presence of advertising.

Eyecon provides all possible information about an unknown or existing contact. Eyecon, thanks to synchronization with Facebook and other social networks, allows you to see a photo of the person who is calling you. Of course, if his account was found on Facebook.

There is a difference from other similar services: data is not searched by the database of phone numbers, but only through social networks. Thus, only users who already use Eyecon can be identified. Of the minuses, a small database should be mentioned in comparison with Truecaller. Service should be used only as a fallback.
