Freezes my iPhone 3GS

Just purchased this app being a RV traveler thinking it would be useful. What a waste of money, freezes my iPhone every time I try to use it. Starts initially, where I normally point my dish to get both satellite dishes (119 and 110). The track is at least 20 degrees off being higher than when I do it manually. When I press done, thats when it freezes my iPhone. Everything is frozen and I have to turn the iPhone off then turn it back on to use the phone again. I have the latest versions of the software per Apples Check for updates.
