I found this app very useful for recording Zwift and outdoor rides, and being able to watch a video of my rides, and sharing them.
Hope other Zwifters will enjoy using it 
interest to know… can you get your zwift ride sync automatically to Relive? tx
How does the Zwift video look? I believe Relive can get no data from Zwift directly - how are the GPS coordinates?
Thanks, Milan
Edit - just tested, Relive is using real GPS coordinates - means for me Paris is ok, the other worlds not (partially London ok, but not Surrey Hills).
