Its just not worth it though, I bought this very app on IOS a few years ago, well it would have been F1 2010 probably. Its not cheap at �20 a pop, and its only live timing, so if its a fly away race which is played back at normal UK times (i.e. repeat) you can't start the F1 app to run in a replay mode, which would be great.
The same app is only tweaked with a new name F1 2010/2011/2012 and the basic team/driver changes and then you get charged a full �20 each year. If your only upgrading you should only pay a smaller upgrade cost.
This app is doomed to failure when you can just go on an F1 site and get the same timing data free.
