I'm looking for stats (traffic, number of users, number of installs, etc) for apps that have been posted in the app stores.

Mostly focused on desktop app stores but also curious about mobile.

Do any of you have any data you can share? There's a massive lack of information on the web about this.

Services like appbot don't have traffic or number of installs.

I want something to compare my app to set goals and anticipate what kind of growth I should expect.
