I'm working on an iOS app called Opal (https://opal.pm/hn) which can help you lock/brick distracting apps on a set timer or all day long in the background while still keeping essential apps like mobile banking active. Think of it as a smarter airplane mode that's designed to help you be more intentional with how you choose to use your phone.
We believe that better and more humane tech is ironically an actual solution to the problem tech has created for all of us. With Opal, it's all about building a healthier relationship with your phone and using everything in limits. It's not about drastically reducing your screen time but you can totally achieve that too if that's what you want to do. We want to make people feel good about the time that they do spend on their screens and not feel guilty that they've spent X hours on their phone this week etc.
I truly believe this can help you get "un-hooked" from apps that are distracting to you and help stop the doomscrolling.
Let me know if you do give it a try as we want to make it work for you and for anyone else in a similar position :)
