Not suggesting we’re Apple by the way, I wish! You can always find a reason to not do something.

The thing is what you are trying to do already exists.
I belong to a few private facebook cycling groups. For mountain biking, people announce time, date and place to meet up and ride. For road biking they do same along with a posting a link for the route that was created in Ride with GPS that can be downloaded onto numerous bike computers. If anyone wants to track where anyone else is at you can use Garmin live tracking or there is an app called Glympse.
Then if you develop an app and charge a monthly subscription fee...less people are going to want to use it.
