Bond helps you to hang out with your friends by sharing your position in real-time. It uses both GPS and network connection geolocation, but it will work anyway if GPS is disabled.
It comes really handy when they keep moving from place to place or when you have to meet somewhere but you are the first to get there. The position is shared among groups, called "Bonds", to which people access using a uniquely generated shareID. You can create one and then tell its shareID to others, or join one already created by your friends, you can also protect access to it using a password or deactivate it if you don't want to share your location momentarily. Anyway the main rule is "you can see others only if they can see you", so you can connect to a bond and see your friends' position only if you have that bond active in your list.
Bond is designed to minimize battery consumption, you can keep Bond running in the background and it will not drain your battery or overheat your smartphone, but it will be reactive when you need your friends' location and when they need yours.
