For me it's less about the tools I use, and more about building health habits (or reducing the bad habits). I use ScreenZen to enforce limited short session for a short list of harmful apps and websites (socials & news), and I configured it to allow a few 5-min-long sessions per day. The short sessions being cut in the middle help me stay informed but break the addictive nature of socials/news. I also use Android's Digital Wellbeing with Bedtime Mode (like Do Not Disturb) and Focus Mode (pause apps and notifications for almost all apps at night). Also uninstalled specific apps (e.g. Facebook) and using the mobile web version, which has subpar experience, which also helps in making it less addictive.
