Welcome, magenta2701332. At this time, FamilyWhere's services allow only the Primary Account Holder to locate the other lines on the account. I can definitely see how a mutual location service would be helpful for a family, though! I did a quick Google search and it does look like iOS devices have a feature called Find My Friends that you may be able to use to do this, and Android users may be able to take advantage of Google+ to track one another. It recommended a few third party applications as well. If you decide to explore any of these options, let us know if you find something that you like!
Hello. Please, please, please...add multiple-user support as a feature request to your team for FamilyWhere. This would seem to be a no-brainer. As one of two parents in the home, I do not want to be The One who always has to locate my child. FamilyWhere has been a great for me. I just wish mom could use it as well. I appreciate the consideration! I'm an Android user.
