I see it's 2 yrs since the question was raised, but thought I'd chime in. I use many separate azzCardfile files for various kinds of contacts, recipes, subscription tracking, and so on. While there is no azzCardfile app for Android, it is possible to export to an rtf file. Then I open that and save it to the cloud as a Word document. This is quick and makes my azzCarfile data available from my Android phone.
