The Garmin solution is not great. I didn't mind the Pebble/Fossil solution. Basically, if an app sends notifications a lot, you can pretty quickly set the setting for it. And if an app rarely sends notifications (like the United app, if you travel rarely) then it will show up by default the first time and you can change the preference if you want. I didn't really mind this process, and in some ways it's better than having to scroll through every app that could conceivably send a notification. I wore my Pebble for almost 5 years — until the battery was down to 1 day — and this was never something that I minded or even thought about. I would slap my Pebble back on if the battery were fixed, for sure!
