How does it work?

Truecaller trades on a give-and-take scenario. If you want those unfamiliar numbers, you need to part with your phone book contacts. This app is crowdsourced by the millions of users who have downloaded the app on their smartphones. As part of the end user agreement, the app will prompt the user to allow access to the user’s address book. The data is then uploaded from the app to the company’s servers. While the service doesn’t charge its users a single cent, the data it collects from your address book is vital to Truecallers’ extension and database.

The algorithm this app uses is that all your contacts are cached when you create a profile. Similarly, when other users create an account, they use your cached contacts and display saved contacts to other users. In the same way, it shows you other contacts.

Truecaller offers an experience that goes beyond the limitations of today’s phonebook apps. It has grown significantly to 250 million subscribers worldwide. With the majority of users in the subcontinent and China. You can also subscribe to the Facebook page to stay up to date.
