How Truecaller works

Truecaller is needed by almost all people of the world, as it displays the name of the owner of the unknown number either we have saved the unknown number or not, it makes an impossible thing as possible. Now, it has made over 100 million fans who have downloaded it. It is a multinational company having over 50 branches all over the world, making it a very big multinational company. 

It was an idea of 2 mans who made it to a very big kudos and idea. Now, it is provided to all the countries of the world, and almost all people are using it widely and happily. The best function is that it reports you about spam calls also. Now, you would wonder that how it works, now let me tell you about it's working concept.

How does it works?

If you want to learn it, you would need to take an example of this app, now let's take an example of this app, suppose that 3 people William, Robert and Tessa have downloaded this app, now truecaller will have permission to use their contacts and will take their mobile an number and contacts data, now it will have their contacts data and their mobile number as well, now suppose that these three people have saved a person's number with names:

William - Chris

Robert - Chris Hemsworth

Tessa - Mr. Chris

Now, if Chris calls a person who has not saved his number, here truecaller will use these names to find a common word which is Chris, and will use the word Chris to display that person who has not saved his name in his contacts, so he would know that this number belongs to person named Chris. By this way, truecaller works, it uses our own data to work.
