What about a Facebook page for the app?
Allow facebook users to stay in contact e.g get informed about updates of the app, bug corrections or new blog posts.

Please vote here if you want to see a separate page on facebook for Finance2C. I will start such a service only if 30 votes are given (10 times 3 votes or 30 times 1 vote).
