Physical barrier on the phone is probably the best way to tackle with such things, but that's not what always available or convenient.

I liked Opal, but with Intenty I tried to create an alternative way without blockers or limits. For some reason, app blockers and time limits are very frustrating for me and rarely work. That was one of the primary motivations for the app creation. While I admit that for the majority setting proper limits on certain apps will work.

Opal is incredibly helpful for me. Exactly the right amount of control and annoyance to get me off social media.
