ThereIam is a geo social app that lets you post Facebook and Twitter messages automatically based on where you are. For example, when you are go back home from work or school , visit a gym or even leaving the city, you want to tell you friends “Leaving Las Vegas right now” . Your exact location and coordinates remain private. So with this app you can define areas on the map and set messages, that will be sent as you enter or leave these areas.
ThereIam uses a low-power way to track your location and only significant location changes are monitored. The bigger your area, the smaller is the chance you position is misinterpreted. The best thing is - messages will be sent even if the application is not running (but only if you want)!
