Never used the Google calendar, but Apple and Microsoft calendars are great for this. I only use the Microsoft one at work, to track shifts, but I get the notifications on my iPhone because I have Outlook on it. I don't like having work email on a personal phone, but I ignore most of it. I can, however, say that the calendar works as it should. Tells me when I need to leave for work and whatnot — usually, just as I'm leaving (I have a pretty good handle on that). I use Apple stuff at home (Macs and the Watch, plus my iPhone). My main calendar is on that. I get a doctor's appointment for example, they want to write it down, I say no need, it's in my iPhone, which means it's also on my Watch and my Macs. The fuck's the paper gonna do? It's just waste.

I'm not knocking Google, I just don't use it. I'm sure it's fine. I have an older Android phone (just on WiFi, it's a backup phone) and I like it, just never used the calendar. Of course the real power move is a calendar that works with both iPhone and Android. There are a few options out there. Most of them are paid, so I'm not even gonna name any. But seriously, digital calendars are fucking awesome. Especially if you have a smart watch.
