Hi Kylon,
I have a Droid Incredible, and installed the Assistant free by Pageonce, and was so thoroughly impressed that I bought the pay version for $7.00. I have my Bank account, all my hotel and airlines memberships, my Netflix, and credit card stuff there, so I too was wondering how this safeguards all my important info.
With my computer, I have to manually type in my usernames and passwords. If I forget to log off, others who get on my computer can manipulate my financial stuff. However, this app is read only. I can only view balances, but cannot see the entire account numbers to my financial accounts (i.e., credit card, checking accounts, etc.). However, I can see my Hilton, Marriott, JetBlue, Delta, American account numbers. Still, no one would be able to use my points, since they do not have my password.
Now I wouldn't go posting all those membership numbers on facebook or the Net, but I guess I feel more comfortable knowing that the phone is in my possession. The same goes for my wallet. If I were to leave that lying around, that would worry we more.
Long story short, I love this app. I can easily check my accounts at a glance anywhere I go, and faster than I can with my laptops or desktop PC.
Let me know what you think if you get this.
