How many users are using which version of my app?
I have released several versions of my app throughout its life cycle. Knowing how many users are using which version of my app would be great.
Something like: %10 is using version 126.96.36.199, %20 is using version 188.8.131.52, %70 is using version 184.108.40.206 etc. on my dashboard.

I think you should consider using google analytics sdk (or something similar) to achieve this.
You'll have more important information: who is really using my app (not only downloaded)
