Is my download ratio growing right? [Estimation request]

Hi, we released our first app 5 days ago, we have 90 active users and 110 installations, but i want to know if that’s ok or not.

Here’s our app :

And some stats:

We promoted the app on several forums, including reddit.

90 Active users from 110 installations is really good. And the stats look fine.

Would you PM the some of the forums where you promoted the app?

Good luck!

In fact i just posted on Otaku / manga / anime forums, or Japanese themed forums. Every site i saw on google writing those keywords.
