Right now its tricky for groups of cyclists to coordinate. It's very easy to get split, and hard to meet a group mid ride.
Owntracks solves a lot of this; but setting up your own mqtt broker is tricky. Some hosted options exist, but then configuring is tricky for non tech users - remote config/config import helps alot; but its not perfect.
Secondly, I have multiple groups I want to share my location with for different purposes.
I really wish the owntracks clients were as easy as the slack mobile clients - easy team swapping, easy signin.
