I already wrote a post related to the Family Calendar, that is a calendar shared among family members.
Another interesting feature available in the Family section of a Microsoft account, are related to activity of children, such as limiting screen time, viewing activity reports (possibly receiving also a weekly email) or finding their device locations on a map. From any activity report parent can limit screen time, block some sites, apps and/or games.
The last feature allows a parent to have the localization, in real time, of each family member added with the child role …
If you go now in the Your Family section of your Microsoft account, you will find this suggestion related to download the Microsoft Launcher app from the Google Play Store to check in with your kids anywhere:
Youi have to login into the Google Play Store with the Google account of the family member, select one of his/her registered Android phones, and then confirm the installation of that app:
Once installed you will find the location of that phone from your Microsoft account site.
There are several apps (e.g. Simple Latitude [*], Glimpse [*], SquadWatch) that allows to mutually get the position on a map with friends (that must obviously accept that!), but it requires that the app is launched at every restart of the smartphone (and possibly at any update of the app), so that a background task is running . Instead, the family localization feature embedded in any Windows 10 Mobile device does not need anything installed.
