Google also has its own solution. Previously, Google offered Google Latitude, but that’s been discontinued. Instead, Google now offers location sharing built into Google+. This does mean you and the other people you want to share locations will all need Google+ accounts.

One big benefit of this solution is that it works across both Android phones and iPhones — perfect for an environment where not everyone has an iPhone.

To use it, install the Google+ app for Android or for iPhone.

On Android, open the app, tap the menu button, select Settings, and select the account you want to use.

On iPhone, open the menu, select Locations, tap the gear icon, and tap “Settings.” Tap “Location sharing” and enable it. Tap “Edit” next to “Pinpoint Location,” choose the people (or circles) you want to share your location with, and tap “Done.”

You can also choose just to share your “City Location” — the city you’re in, but not precisely where you are — with a wider variety of people.

People who want to share their locations with you will all have to do this on their phones, and you’ll have to do it on yours to share your location with them.

Go to the Locations section in the Google+ app to see these locations.
