A location tracker.
So, if you have looked at the introduction page you have seen how I can use location information on your device to show you on a map where you are. This is not really very impressive in itself as there are mapping sites (e.g. Google) that have been doing this for years. But we have to start somewhere. This page takes the next step and once you click the go button it will constantly poll your devices location services for updates and then update the map and the location information automatically. Basically it just means you won't have to keep clicking the button.
Something else is available here, though, for mobile users. There is a thing called Wakelock which I can access. If I turn this on then your phones screen should stay active. As this could be a bit of a drain on your battery I have provided a button for you to toggle this on and off.
