Something I realized recently is that I'm not addicted to social media or any apps in particular, but I am addicted to my phone. I managed to give up pretty much all social media, save for an occasional peek at reddit and this site, but still take out my phone about as often as I did before. Mostly I just check the news for the umpteenth time in a day. My current plan is to keep using my phone, but switch to using it for more productive things. For example, I started using Anki for memorization and I use a bunch of music theory/sight-reading apps.
I have an entrenched Anki habit – I picked it up while studying for an exam, and now it says I’ve been using it for an average of 17 minutes a day for 2 years. It’s a great tool and I recommend it. But I don’t think it helps to fix the phone addiction problem. Getting to an average of 17 minutes was hard work that required a lot of willpower. I’m sure most people with a phone addiction problem are spending much more than 17 minutes a day on unproductive scrolling.
Similar realization here. Just can't get myself off the damn thing - doesn't seem to matter what I'm using it for. Hopefully the more productive route works for you!
