Firstly, I'm looking for a single Android app that replicates Blasts "Great Big Binder of Everything with Everyting Inside" (GBBEWEI or GBB, for short).

This would be an electronic version of the printed binder. I've looked at eWallet and don't think that goes far enough. If anyone has experience with it, please chime in. I have an android phone and two android tablets, and want auto updates to all devices when updating info on any device..cloud backups too I can access from any device.
Would dropbox do all that?

Secondly, sorry if this has been covered, but when I tried a site search over 25 pages came up and I went thru about ten before admitting defeat.
