No XT is a call blocking application designed for iPhone users. Developed by Operadora del Consejo Ciudadano del Distrito Federal A C, this app aims to protect users from phone numbers associated with extortion.

The main feature of No XT is its ability to block incoming calls from numbers that have been identified as sources of extortion by the Consejo Ciudadano. When a call is detected from a number on the blacklist, the app automatically blocks it without any notification to the user.

It is important to note that No XT requires internet access to update the blacklist, which is done sporadically. This means that the app may consume mobile data.

With its focus on call blocking and protection against extortion, No XT provides iPhone users with an additional layer of security and peace of mind.
