Android App initial release date When you are viewing an app in Google Play store, it displays the following : Updated, Size, Installs, Current Version, Requires Android, and Rating.

I am trying to do some research and figure out the initial release / publish dates of different apps. Is there a way to get this information from Google Play, or perhaps a website with this information?
Check in www.appbrain.com for Android apps. It shows all possible information about app. Moreover, it shows release dates with respective released version numbers and number of downloads.
