Android - Android App initial release date

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.

May be not NO!

But if you need to get this information, you need to check the comments section if there are less comments, you can analyze that the least commented DATE (or approximately) will be the initial launch date of that app.(Assuming that every developer starts giving ratings and reviews as soon as app launches to boost Downloads.)

OR

if you have access to developer console, You can check there under "current installs" section, the starting point's date on the Graph will be the Launch date of a particular App.

Also, in developer Console -> under your application -> Select Statistics -> then in the Box after "STATISTICS" heading Select "TOTAL USERS" option and then to the far right in the same line, with the option "SHOW", Select "ALL". Now in the below graph, you will be showing some pin points dropped, which indicates your respective published versions of the application/game in google play. If you hover at the first pin point on the far left of the graph, it will show "JANUARY 1: Published version 1".

Here obviously Jan 1st will be the date at which your application has come LIVE on Google play.

Respectively, you can get all the successive dates of your app updates.
