Ever wanted to know how well a particular app is performing in the app store? Analyzing someone else’s app performance and/or general app trends can offer valuable information that might guide your own app development. In this article, we’ll look at what information is publicly available about apps in the app store.
I examined numerous websites in preparation for this article. However, there are so many that it felt daunting to examine all of them. I selected my favorite website for each piece of information and included it below. Note that my primary focus was on iOS performance, although many of these websites include Android performance as well.
App Rank History: App Annie
Checking out app store chart rankings within various categories over specified periods of time is easy with App Annie.
Find the Number of Downloads for an iTunes App: Programmer Interview
There is a link to the full 25 page academic paper that explains where the formula came from, but if you just want the quick down and dirty, the Programmer Interview post lists the formulas. That can be used in conjunction with App Annie’s Rank History to calculate a rough estimate of paid app revenue (IAP & ad revenue aside).
Global Download Count & Summarized Reviews: Xyo
Another option for quickly getting a rough estimate for a global download count, along with trending app review buzzwords, & an aggregated/intelligent app score can be found at xyo.net.

This great website lists all historical pricing & version history for all iOS and Mac apps. Additionally, you can set alerts and have it notify you when the price or version of a particular app changes.

Flurry is a blog that I love to read. Being one of the most widely used analytic sdk’s available, they have excellent insights into the trends of the app store.
App Analytic Tool Comparison: Moby Affiliates
