Thx for sharing, great numbers. Some questions: - Via which channel did you communicate with your early users / get feedback? - Did you collect your user's email addresses from the beginning, upon installing the app - or at a later time?

At the very beginning we got feedback from the comments on the Android Market but we were always very open with our support email address (it's in our store description), so we could talk with our users directly.

Right now, users register with their email the first time they open the app.
