Does anyone know a safe whatsapp alternative app for teens?

Studies have shown that parental involvement in monitoring online activities can significantly reduce risks for teens, and apps like Kaspersky Safe Kids and Qustodio offer a range of controls, including message monitoring and app blocking (Hertz et al., 2017). Research suggests that a balanced approach, combining technical controls with open communication, is most effective in promoting digital safety and trust in parent-teen relationships (Padilla-Walker & Coyne, 2011).
