Google Location Sharing
If you have a Google account and a smartphone (Android or iPhone), you can share your location with other Google users. This is useful for families to share amongst themselves, and the sharing permissions can also have a time limit so it could be used, for example, to share your location with a pending dinner date or meeting host. Full instructions on how to set this up can be found here. I use this feature often and have found it to not be instantaneous, and it has some hiccups when refreshing, but it is still a handy way to see a general location of someone else without resorting to a third-party app. Speaking of location sharing, you are also likely sharing your location with Google even if you never intended to. This is ostensibly to show you search results relative to your current location (like for nearby restaurants), but it can be a little disconcerting to see everything your phone is logging.
