Alohar Mobile, the location startup led by ex-Google Maps architect Sam Liang, on Wednesday launched a new iPhone app called PlaceUs that tries to add contextual intelligence to location sharing. PlaceUs aims to help people stay connected with a close circle of loved ones. As the app learns your routines, it can do things like automatically send a message to your spouse when you head home from work or when you’re stuck in traffic on the way to daycare. PlaceUs can also notice if you haven’t been to the gym in a while and send you a reminder. Alohar claims that PlaceUs can also keep track of how much gasoline you’ve used by tracking your speed, routes and distances. Once it notices you’re running low, it can initiate a search for a gas station automatically.
