I must say, we were very eager to play with our new devices i.e. beacons. When we finally get them, we started to push this piece of technology to its limit. We tried every possible function provided by the producent. We weren't quite happy with beacon accuracy, but after some work, we manage to get satisfactory results. We create an aplication capable of precise tracking android devices using GPS and beacons. Our aplication can be used in most places e. g. shopping malls, factory, mines as a safety system. When some kind of catastophy happens and it will be required to quickly find and rescue someone from a debris, Eboloid 0.7 will be a lifesaver. Of course there are many more applications.
