LOCO is a all-in-one location sending and tracking platform. LOCO has 2 components
The sender component is used for sending the user location to the server. When you sign in LOCO, your email is used as a unique ID which can be shared to other people. Then others can have your live location updates
The receiver is used for live tracking a sender's location. Ask your friend for their ID and use that ID to track them. When you are tracking, your friend should also be updating at the same time
Loco allows the user to share his/her live location and one or more of their friends can track it live. This is very useful in bus tracking or when you go out with friends on a trip.
