Pebble was exactly what I wanted 10 years ago and exactly what I don't want now. I'm very happy to miss notifications when my phone is in my pocket or bag and I don't care about fitness metrics anymore. However I'd love to leave my phone at home while still being reachable...
I do use pebble for (something like) that. I find that setting it up so they certain people can get to my wrist makes me check my phone less. So I get sucked in less.
