First of all, the app is an extension for a sim racing cockpit. I build this app to have a real speedo on top of my racing wheel, like you see in the videos.
This app support many favorite racing games, not only LFS. Hardware devices that are have basically the same features are a lot more expensive. And you do not get a second screen for free, too.
I hope I can add some games more in the next weeks like rFactor, F1 2011 and Dirt 3.
Some feature additions are on my TODO list, too. :-)
And to answer your question:
If you do not like it, do not buy it. So easy.
Or if you have some wishes you want to add, what you do not find for free, send me a mail.
Greetings from the developer. :-)
