Back in May, Rovio announced a new "Rovio Account" feature that would allow users to sync their progress on games such as Angry Birds across devices. At the time, the feature launched with limited availability, arriving worldwide for The Croods and only in Finland and Poland on the original Angry Birds game.

Angry Birds for iPhone [Direct Link] and iPad [Direct Link] are available in the App Store.We know that you've all been waiting for a way to sync progress between devices and we really feel that we have an amazing solution in place now.
For now, Rovio Account is available on the original Angry Birds game, as well as The Croods. The next step is for us to roll this out onto other Angry Birds and non Angry Birds titles, so that's exactly what we're going to do!
