Good morning Steff,
I have only begun looking into the incompatibilities between the two platforms. I wished it were easy to develop a portable app, but it really isn't.
On the other hand, I have revamped the app and it's supporting database so that the data is maintained in
JSON format. JSON is portable, so should I or someone else choose to develop an Android app, we have suitable data. That's a big step in the right direction and represents a huge time saver.
At this point, I'm ready for a break. This little hobby has been more work than I anticipated. I am actually considering doing Robert's Rules of Poker (RRoP) soon too. Of course, there are several other ideas bouncing around as well. Some may even make a buck

.
Stay tuned,
~B
