Blokada is the original version of the app. It's available on our official website, blokada.org, as well as on F-Droid and XDA Labs. You can also find our official mirror links on our GitHub and BitBucket.
Blokada Slim is a simpler version of the main app, available on Google Playstore. It offers some of the functionality (like DNS changer and Blokada Tunnel), and also receives updates at the same time the main Blokada does. It does not contain features that Google Playstore policy does not allow us to include, namely adblocking and in-app payments (you need to activate your Blokada Tunnel account using our website instead).
