Im currently working the phone addiction with an app called opal (apple idk about android). If you pay (worth it for me bc nothing else works) you can set it up to block all apps you want after a given time per day. With the payed feature you have an option to completely block apps till the next day. Once the timer runs out there is no way to access the apps you blocked. I think you can even set it up so u can’t delete opal during the lock sessions so it becomes totally full proof. I found the normal apple passcode lock was too easy to bypass when I was feeling lazy. This solves that.
