Hello; Maybe the most important option is that you can set up your own position and see how it goes with the help of engine. About two years ago, this app has that option maybe with the best engine on the earth and it was easy to figure it out. But today I'm not sure that you remove such a important option from your app or you complicated your app that It's not easy to find it out at all. Please help ME and get your 5 stars back!
