In an attempt to be more present with one another away from our phooes, my partner and I have (ironically) started using old phones as single-app devices.
For example: we have a "spotiphone" which is an old iPhone with a shattered camera that has only Spotify installed that we use in our bedroom to control music/podcasts. Similar thing for where my partner meditates (but it's an old iPod touch).
Our real phones are usually left by the door when we come home.
