NimbusBase, an open iCloud for Android

Hi, I'm William and I coded NimbusBase Android, a storage solution that backs up all the sqlite data on a user's own Google Drive/Dropbox/Box. It's kind of like an open iCloud for Android.
We just released an beta and are looking for adventurous developers who wants to back up their user data on this solution.
Here is our developer page "nimbusbase.com/articles/learn-android.html", take a look and tell us what you think. You can also email me at release@nimbusbase.com if you have any questions.
Thanks!
