Q: Google Play Store: App page does not show download statistics I have developed few apps, and published them on google playstore, but it is not showing number of installs to user.
What's wrong in that, can you help me in that?
Look at this screenshot to understand my problem,there is no additional information shown for number of installs

My apps can be seen here.
By the way is google analytics code neccessary to show it?
I didn't implemented analytics code in my app.

A: 
It is not showing number of installs to user.

For new apps it takes around 1.5 to 2 days before the first set of download statistics show up. (if there are downloads during that period). Ratings on the other hand reflect immediately.
Also, If you see in on your developer console and not on your play store app: clear cache for the playstore app and restart the play store app. It will show up.

No, implementing analytics in your app is not necessary. But, it is recommended if you want to have more accurate and sometimes real time overviews of your app details.
