Hello I plan on getting an apple watch sport for high school, I was wondering if I can just bring the watch only just to keep track of time and my calendar as this I don't know what's going on in my day or it can get confusing. I would save all the calendar events on the phone, it syncs onto the watch hopefully and it keeps it there. Instead of carrying a piece of paper around everywhere and risk losing it. With the phone I could get in trouble with the phone. The watch is less noticeable and more confident from my stand point. I've read the manual and it doesn't mention it only mentions activity emails and stuff. I'm a bit confused as I don't want to carry my phone around everywhere in high school which could be risky as it's very easy to lose. Would you be able to use Siri without wifi? I know the iPhone can't but I was wondering if they changed it.
