Welcome to the Forum!
You English is very good, I have no trouble understanding it. I can't answer your question on, if the GB App will be available for two person users in the future. One of the App writers will have to answer that question for you.
Have you considered buying you or your wife an iTouch? The App works well on the iPhone or iTouch, as well. The iTouch is less expensive, as you may or may not know.
Good luck to the both of you with your managements!
