HangOut is a simple Android app to share your location with family and friends, so they know where you hang out. You can share a link with an expiry time, so others can follow your trip real-time on the map until the link expires. HangOut can automatically send a text message when you have arrived safely at you destination. If you enable the GPS, colored dots from blue (0 km/h) through red (50 km/h) will indicate the velocity on your trip.
