The NoPhone
This is fun and all, but also incredibly sad. My fiancée previously complained that I was staring at my phone too much (and she was absolutely right). So, I decided to minimise it. Remove all apps and notifications, and kept it in a corner of the kitchen instead of in my pocket.
Even though she has not increased her screen time, it is now obvious to me that SHE is staring to much into that screen. We are all phone junkies.
