I am an avid user of Waze. One of its feature is the ability to share your location with followers or through text messaging. This is quite handy when you are on route to appointment while being stuck in traffic. You simply sent a message and the recipient can follow where you are and when you'll arrive.
Unfortunately, only works when driving. It does not cater walking, cycling or public transportation. Does an equivalent of waze exists, which would allow you to share where you are. I would very much like to use this while traveling with a group.
A google search on the matter reveals some apps, but these are mainly aimed at couples who don't trust each other, where you would need to be sneaky when installing the app the phone of the person you would like to follow.
I would like to be able to simple send a text message to have someone be able to follow me, similar like the approach waze is taking. Does such an app exist?
