Friends!
This link is available in the APP Slot_up to install on Android smartphones (Samsung etc.)

And 'ready for iPhon and iPad but the timing of Apple to make it available in the' App Store are rather long.
The App is dedicated to the WEC, you can follow the progress of the race live, take photographs with frames set pre and post them directly on Social.
good fun
