I’ve been in a similar predicament :-) I deleted the app on my phone, it still gives me the option to look up insta on my laptop but it’s not available all the time for useless scrolling — which is the reason why I deleted it.
And on top of that there is an app called ScreenZen (I’m sure there are more) where you can limit your app usage (I have it set on 3 times a day for tumblr and reddit for example) and it’s working really well for me! Can only recommend!!
I know I can't shake instagram for good, i'm not that strong, but I deleted the app and only go on the browser when I really feel like I need to be on it. makes it a much less desirable experience and I spend way less time on my phone in general
i have an iphone and deleting instagram off of my homescreen (so that i can still access the app if i want) is a game changer. it helps to curb the kind of muscle memory you get from opening it automatically to begin the mindless scroll. i still check it maybe look at a few posts but overall i'm barely on it now. i would spend 2+ hours a day on it scrolling mindlessly and by best time was thursday when i spent a whopping seven minutes on it!!!
I still go on a couple times a day while I’m on the computer but that amounts to about 20x less than I would be otherwise. Brings down screen time more than you’d think.
