BetBlocker is a free Android application designed to assist individuals struggling with gambling addiction by blocking access to gambling websites and applications. The app utilizes Android’s VpnService API to create a local VPN, ensuring that all filtering occurs on the device without transmitting data to external servers. This feature is crucial for users seeking to limit their exposure to gambling-related content effectively. Additionally, the app employs the AccessibilityService API to monitor foreground apps and restrict access to those that may encourage gambling, providing an extra layer of protection for users who opt for enhanced blocking capabilities.

Once activated, the app cannot be removed until the designated exclusion period concludes, emphasizing its commitment to helping users avoid gambling temptations. For initial testing, users are encouraged to utilize the 'Parental Control' mode, which allows for easier disarmament via a password. It is important for users to understand that technical support focuses on resolving issues rather than removing the app, reinforcing the app's purpose as a long-term support tool for those in recovery from gambling addiction.
