Google Maps is in the process or rolling out a location sharing feature that you may actually want to use. Location Sharing is something that has been a bit spotty for both Android and iOS with Apple probably having it figured out best with Find My Friends. But, as is usually the case with Apple, it is only for fellow iOS users. That is why this new feature in Google Maps is so exciting. It works cross platform between Android and iOS.
In a nutshell, here is how it works. When the feature rolls out to you, there will be a Share Location feature in the menu. Tap it then select the contacts you want to see your location in real time. You can set it up to share your location in real time for a set amount of time or until you turn the feature off. Once you start sharing, your selected contacts will get a notification on their phone and when they open up Google Maps, they will be able to see where you are in real time.
