'Experimental support' for mobile worries me a little, though... guess we'll all be beta'ing for a while then!
its declared experimental for now because
1. it's not completely finished. savegame screenshots (iOS) and savegames (android) are not implemented yet.
2. android package cannot be exported, but it's easy to manually assemble an app (information is in the Wiki).
btw, nobody is forced to use this feature yet

for now we're showing what's currently possible and I guess it won't take long until it will be complete. Especially considering Simon did all the hard work for iOS in less than a year.
