A1 Guard is a utility app for iPhone users that aims to protect their loved ones from phone scams. With this app, users can set up incoming call restrictions for designated "Protected Users" from their trusted contacts, known as "Managing Users."

One of the main features of A1 Guard is the ability to create an approved list of phone numbers that are allowed to call and connect with the Protected User. This ensures that only trusted contacts can reach the user, minimizing the risk of falling victim to phone scams.

Additionally, A1 Guard offers settings to determine the possible ways incoming calls can be handled for the Protected Users from numbers outside the approved list. Users can choose to allow these calls, reject them without connecting, or redirect them to the Managing User.

Furthermore, A1 Guard provides notifications for every attempt to call the Protected User from a number outside the approved list. This feature helps users stay informed and vigilant against potential phone scams.

Overall, A1 Guard is a valuable tool for iPhone users who want to protect their loved ones from phone scams and ensure that only trusted contacts can reach them.
