What is a VPN App?
🔍 Quick answer:
A VPN app is software that connects your device to a VPN server, encrypting all your internet traffic and hiding your IP address. It's the user-friendly interface between you and the VPN service. With one click, it establishes a secure tunnel, changes your virtual location, and protects your privacy. VPN apps are available for Windows, Mac, iPhone, Android, and even smart TVs and routers. Most offer features like kill switch, split tunneling, and automatic connection on untrusted networks.
