On playing around with my iPhone setup lately I’ve noticed that for those apps you want to use less and don’t want to delete, simply moving them off your main Home Screen or into the App Library might be enough for you to use them less.
I’ve found that not seeing them as soon as I unlock my device has helped me stop using them completely.
Before deleting social media apps I moved them and my usage went right down. I’d moved the habit of unlocking and loading them. After a week I just deleted the apps and don’t miss them.
Give it a try for your social media apps, move them away from where you can see them.
