This application is a flexible configurable call blocker. It supports manual entry of blocked numbers as well as a downloadable list of known callcenters and other unwanted sources of calls (mostly in Switzerland as the list used is from the K-Tipp website).

Additionally you can also set it to only allow calls from numbers listed in your contacts.

If the app is enabled and you receive a call from a number listed on one of the block lists then the call is hung up and a notification about the suppressed call is shown.


Currently only the download of numbers listed on the swiss K-Tipp website (https://www.ktipp.ch/service/warnlisten/detail/w/unerwuenschte-oder-laestige-telefonanrufe/) is supported. This may change in the future. If you want additional lists to be supported please drop me a note about the source you want to see supported.
