Today is my one year anniversary of writing Weekend Coder posts here on CrackBerry. Much the same as companies report end of year data (sales numbers, market share, etc), I thought it would be fun to do the same with app data. So I am going to do exactly that using the data that BlackBerry provides in the “Download Reports” section of the BlackBerry World Vendor Portal.
Inside the Download Reports section of the Vendor Portal, developers can request .csv files of raw data about downloads and purchases of their apps. However the problem is that it is very raw data. To make it useful you need to apply some logic to it. Drawing from my personal career knowledge (where I was a project manager for many years and now a director of department), I have come up with a fancy Excel spreadsheet that will create graphs and charts for you. The download link is at the bottom of this article.
Using my spreadsheet you can get totals/percentages of various breakdowns such as by device, by OS version, by country, etc simply by pasting in the raw data from the Vendor Portal into either the Purchase_Data or Download_Data tabs and refreshing the Purchase_Pivots and Download_Pivots tables. This will update the tables on the two pages with your data as well as update the graphs on Purchase_Dashboard and Download_Dashboard.
I have purposely picked what I think are key metrics to help myself and any other developer to analyze their user base. For instance, analyzing the device breakdown graph lets you know how well you are doing in hardware keyboard versus all touch. Perhaps a large proportion of Q10/Q5 users means those are the users you should target or conversely perhaps it is an indication that the full touch version of your app needs improvement.
Another interesting metric is OS breakdown by month. I will admit I took this graph type from a developer friend of mine (Ebscer, creator of Pixelated, Xploding Boxes, and more) which I believe helps you see where the market is in terms of OS updates. If a large percentage of your user base is using OS 10.2.1 perhaps you can discontinue support of OS 10.1 (and lower) to make use of newer API and not worry about alienating the majority of your users.
A few final notes, first in column O on my Purchase_Data tab, you will need to come up with that value manually. If you are good at Excel you can populate the field relatively quickly using vlookup. Another thing, once you have your raw data in, you can apply various filters in the graphs such as looking at only BBOS or only BB10 OS in the “OS Breakdown by Month” graph.
So I encourage you to download my spreadsheet to help you analyze the raw data BlackBerry provides from the Vendor Portal.
I thought some of you may be curious about my apps data,so I have run the past 16 months (Jan2013-Apr2014) of data through my Dashboard. My data during that time period consists of 211,081 Downloads and 9,256 Purchases (mix of paid apps and in app purchases) of my 22 apps.
