app-store-ios-numbers-rankings
==============================
Version 1.0 July 17, 2012 12:57 AM
This is a simple app that gives detailed app store information in a very flexible implementation. I'm trying to take the guess work out of real numbers: downloads, revenue.
The premise behind this app is to use app store reviews to gauge how many times an app has been downloaded. A common industry standard is 1 review on the app store equals 400 downloads. This is the default implementation which is configurable settings.
Free app revenue is based on a advertising revenue stream, estimated ltv of $0.15.
The 'F' or 'P' at the beginning of each row indicate Free vs Paid.
Shortcomings (yes there are many)
- Accurate downloads? Download numbers are hidden by Apple, no. of reviews are the only way to best guess how many times an app has been downloaded. Is 1:400 an accurate ratio? Who knows. That's why its configurable.
Do apps that prompt users to review get more downloads/ratings? Probably. Do certain categories or passionate apps attract more reviews? Most definitely.
-
Accurate revenue? Revenue is based on downloads, see above. Other problems are price changes and in-app purchases. Both are not taken into account.
-
Free app revenue. There is no real way to estimate how much a user is worth. $0.15 ltv is a bit high for some apps, low for others. Also, many have 0 advertising. This is just a best guess.
Notes
- Please do not start writing to this parse db. If you wish to host your own db, please change the parse api key.
Bugs
- Sort by rankings does not sort by number of ranking. It currently sorts on server side by revenue at 400:1 ratio. Need to add 100, 200, 300, 400 pre-calculated revenue to db and sort based on those.
