GB Pro vs. GB
 

What is the difference between the GB Pro app and the GB app?

I have the GB app and love it. I did buy all the premium features already.

Also, I'd love to see sync in the Android app and/or a iPad app.

I believe that the Pro has the BP & WT built in. I don't think that it is any different than what you are currently running. However, since I have not seen the Pro I could be wrong.
