Question

What is the difference between total installs and active installs?

I have 90 total installs for my app and only 47 active installs. What does it mean?

Answer 1

But We must consider that Google Play statistics has some delay, usually (on this case) of one day. You will only see tomorrow the number of today's downloads. Evaluation, on the other hand, can be published almost instantly (numbers of 5, 4,... stars).
