What is a good "active installs" rate for a free Android app? [closed]

Question

My free app has received many positive reviews and has a 4.5 star rating on the Android Market, but the active install rate is less than 40%, meaning more than half the people who download it uninstall it.

Is this normal? I would assume a highly-rated app would have closer to 100% install rate.

Answer 1

It seems like there is no official data from Google about this, but I did find this discussion:

Here is an estimate from data collected from a few friendly developers.

The best or essential - ~ dozen free apps, have a retention ratio above 75% - ~ 100 free apps, have a retention ratio above 50%

Rest stay below 50% after the first month and average at around ~30%.

Paid apps work in a different way for obvious reasons.
