What can AAA do ?
The point to note here is that most tasks you can do On-line with AAA can also be done Off-line. For medics and communities that don't have a regular internet connection, that's significant. For people who also can't afford expensive EHR systems, it's a major leap and because it's free, that makes it available to everyone. That's important.
There is also a background 'Live Tile' mode so you don't even need to run the app to see how busy your group is (You can also have TOAST\Pop-up notifications if you want).
Here are a couple of sample use-cases for AAA.
