The texting is actually pretty good from the watch, can use Siri or type into the watch keyboard. Same with phone calls, I use the air pods to connect and its like talking on a regular phone.

Apple pay works very well. Get emails, slack messages, etc. Can easily reply to slack messages from the watch. Cant see conversations but

Basically everything works that I need.

Alot of apps dont work, but thats the point. I dont need those apps all the time.
