Not exactly what you're talking about, but I recently got a cellular Apple Watch and I've been trying to have only that with me as much as possible. I can do all the things on your list from it and my distraction plummets whenever I leave my phone at home and just have the watch. But I still maintain the bare minimum of connectivity and conveniences like music/podcasts/calls (with airpods)/texts/gps. Just not having the ability to open a web browser or reddit while having those less distracting essentials is the perfect balance for me.
