Whether for purely social or for pragmatic reasons, it's often necessary to let one's friends know when you've arrived somewhere, and the HMU app is a new social tool that helps users to do just that. The location-based system conducts one simple task: it sends notifications to users within a given social network when one of those friends has arrived at or left a specified location.
Typically, users text their friends with their ETAs — sending a quick note when they've started the drive up to the cottage or when they've gotten home safely after a night out — but it can be easy to forget or, in the case of driving, downright dangerous to send those messages. The HMU app is a social system that uses GPS to send notifications to one's specified friends automatically. The system helps friends to organize with one another and keep tabs.
