On top of what's suggested in the post, I found the following helpful:

- having a "phone box", the small uncomfortable shoe bench now has a shelf above it for phones, phones shall only be used on that bench

- only my partner knows the "screen time" password on iOS

- putting away my laptop and using a desktop computer instead

My current problem is listening to podcasts, I don't have a convenient way to listen to them without my phone.
