Block alcohol website age gates with Twenty One! Believe it or not, age gates on alcohol-producer websites are not required by law, and yet several websites pop them up over the page content, hindering your view. Worse yet, many of these age gates have not been designed for mobile devices. After a few drinks, it's incredibly hard to enter your birthdate over and over again. We all just want to view the content! That's where Twenty One can help. Twenty One maintains a constantly-updated list of alcohol-related websites and disables them efficiently with iOS's new Content Blocker technology for Safari. Keep in mind that not all age gates can be blocked and that content blockers required a 64-bit iOS device. This app is open-source! Visit https://github.com/gfiumara/TwentyOne for more information.
