We've now added 120+ circuit maps to the App, so that when selecting a race event you can see what the circuit looks like. In addition to this information we also give the circuit length and a URL to the official website of the race circuit selected.
There will be a couple more updates and then we will create a Paid For version which will add more functionality to the existing free functionality. The Free version will continue to exist and will be updated, but may not gain all of the functionality of the Paid For version.
Please keep the feedback coming, it really helps to get a feeling for how the App is being used.
