Is there a way to use a cloud vault from my ipad to a android phone

Thanks

Nope, Android is tied into Google Play Services, no chance of being able to transfer a save game from iCloud over to Google Play / Drive.

This is why most sensible developers use their own servers for storage, as they its tied to an account on that server rather than an OS specific account.

But I guess we should be grateful for cloud saves in the first place.
