Ok, so I just got my apple watch, and the thing I'm most excited about is using it as a cell phone replacement when I don't need a big screen in my pocket. In my first two days of testing, I love the freedom that it gives me when I do things like go to meetings, hiking, etc where I don't need my big screen, but it does suck juice when on GSM! I know it's early days, but I thought I'd share apps that work, and apps that don't and see if anyone else had anything to add. My watch is on t-mobile. Here are apps that work with 4.1 over LTE with phone switched off (after initial app install) Lyft Shazam Itranslate converse Most apple apps - Maps, Apple music, Mail, iMessage, ... Apps that don't work yet without a phone: Pandora Spotify Uber (not that I want to support a crap ethics company) Delta BBC news SPG Yelp Flipboard (doesn't even work keeps telling me to login) Notifications that will now need apps that don't exist to work on LTE; I am unclear if they work if you leave your phone on at home Google voice Google Maps Any more that work with LTE?
