What is a good “active install” for a free Android app?

Question

My free application has received many positive reviews and has a 4.5 star rating on the Android Market, but the active installation level is less than 40%, which means more than half of those who download it.

This is normal? I would suggest that a high-rated application would be closer to a 100% installation speed.

Answer 1

It seems that Google has no official data on this, but I found this discussion:

Here is an estimate from data collected from several friendly developers.

Best or significant - ~ a dozen free apps, retention rate above 75% - ~ 100 free apps, retention rate above 50%

Rest remains below 50% after the first month and is about ~ 30%.

Paid apps work differently for obvious reasons.
