I can not use the app now, because I am now on kitkat. But, what I think, is that it is a rather big app, installed it is about 4mbs, for an app with no gui. And also, there is also a app that does what yours, it is "MT GPS EPO Fix" ad works as it should. What is needed, imo, is a small app that does this, but also has a schedule capability. Only my opinions my friend!
