Facecaller

It's surprising that it took so long for someone to make an app like Facecaller. All of its features are so good, once you start using them, you'll never be able to live without them again.

The main advantage of using Facecaller is the ability to have total control over the calls that are made and received on your smartphone. It looks similar to other smartphone call managers, but if you look closer, you'll see that Facecaller has tons of other features that are as useful as they are surprising.

Besides basic features like a dialer, SMS, and call log, Facecaller also lets you block calls from certain numbers, analyze whether you are the victim of some kind of harassment, show the level of the threat, and reveal hidden numbers - and all of this without consuming too many resources and taking up very little space on your smartphone's memory. What do you have to lose?
