How to find how successful an iPhone app is?

Question

Like for websites we have Alexa.com which show site analytics of the site and its rankings, etc.

Is there something similar for iPhone Apps?

Basically I want to know how successful an App is. I know we can guage it by seeing number of user reviews but at times there are not enough reviews and it becomes difficult to guage the success of that app.

Answer 1

We use appannie.com for our tracking... it's quite good.
