I bought a thing as a solution for exactly same problem. Don’t want to tell a specific brand, because IDK if it’s allowed here. Essentially they send you a physical device with NFC inside. You use their app to put a phone in distraction free mode and the only way to unblock it is to tap the object. It helped me a lot with my social media addiction. Probably, the best investment I ever made.
Maybe I can first get myself addicted to using my phone instead of my desktop for entertainment media and then limit access to the phone and hopefully not rebound back to the desktop. :) Putting my desktop inside another physical device seems difficult to make work, but yes I agree this is the sort of solution I'm yearning for. I'm happy it worked for you.
atleast tell what to amazon search for
You are allowed to name the brand.
