Proprietary???

Cmon you guys, a fabulous app like this and it only works for your external add-on device? I would buy this app in a heartbeat, pay money for it if it worked on my internal iPhone 4s GPS, better yet make it work on the iPad too! It is exactly what I have been searching for only to download it and be disappointed that it wont work on my phone without your external device. What a let down. Maybe some other developer is willing to plagiarize your app and make it work for the masses.
