Callfilter.app is a popular app for blocking unwanted phone calls. The app uses its own database of unwanted calls, which is updated by its users. Currently there are more than 2 million Callfilter.app users worldwide.

One of the main advantages of the app is its anonymity. Callfilter.app does not get the phone number, email or other identifiers of the user who uses it. It does not copy or transfer any user data, including contacts and SMS, to the server anywhere. Each time the app is installed, a new one-time identifier is created that is not associated with the user or the phone.

Callfilter.app blocks the following types of calls:

  • Robocalls
  • Scams
  • Advertisements
  • Collectors
  • Solicitors

And other calls that nobody wants to receive.

Callfilter.app is developed by an experienced team of developers and is well optimized. The app is less than 5 megabytes in size and does not consume much RAM and Internet traffic.

We will be glad to see you among our users! Welcome!

I got a call from 833-763-2031, and they said they were from my bank's fraud department. They had my name and the last four digits of my card, which seemed pretty convincing. But then they asked for my full Social Security Number and address to "verify" my identity. I got a bit suspicious, so I hung up. (robocall)
