Google just announced via email that it will remove its Trusted Contacts app from both Google Play and the Apple App Store today. However, it has added the same feature to Google Maps with its location sharing feature, so you can still share or track contacts that way.
Trusted contacts were originally launched over three years ago as a way for people to remain aware of the whereabouts of their trusted friends and family members. Even if the app is removed today, Google will continue to support it until December 1, 2020, so you can still use it for another month.
You can also download all trusted contacts that you have created from the Trusted Contacts page before the December 1st break. At that time, the app no longer works to share or view locations. If you’d like to continue viewing and sharing location updates after December 1st, you can download the free Google Maps app on your iOS or Android device.
