I'd like to try BikeControl for virtual shifting. On the web site it says "Free to Try", but when you click through to the app store it looks like the only option is a $5.99 paid version. And then there are also In-App purchases with a bunch of pricing options, including a $4.99 Full Version Unlock.
I'm failing to find any sort of pricing information on the BikeControl web site. I'm guessing I'm just not seeing it. Anyone have a link that describes the different pricing options and how to get the "Free to Try" option? I'd like to make sure it works on my setup before getting a paid version.

Thanks!
