I am glad to announce that test on the races last weekend showed that my app is working pretty well.
I fixed some most annoying issues and now it has the following functionality:
- List of the races for 2012
- Live timing for each part of the race (Free Practices, Qualifying, Starting Grid and Race)
- Live timing. Refreshes every 30 seconds and can be stopped/started by menu button
- Historical data from 1956-2011
UPDATE: App is available on Android play
I upload new version of app with fixes, get it from here
