I’m going to share the download numbers for Currency for the past 13 weeks (well, for the US, UK, Japan, and Australia — there are too many regions to fit on one chart). This chart is also only for new downloads, not updates.
Unfortunately, Currency has not been in the top 100 free apps in the US app store for quite some time (I’m actually not sure when it fell out), so I do not have data to compare it against to to see how the download numbers change in regards to position in the app store (I may have that data for another app that I develop, but since I am not the owner, I cannot share that information at this time).
(The 1.2, 1.3, and 1.4 stars represent the releases of the respective updates of the application). You can clearly see a bump in installs after the 1.2 release, but not after the 1.3 or 1.4 releases. I assume that sometime in between those releases Apple stopped bumping up apps in the lists for releasing updates (as a result of some developers releasing updates that didn’t really do anything just so they could keep getting that bump).
Obviously the US has the largest number of downloads (although the app is available in all markets and all 18 languages that the iPhone supports). However, I am a little surprised at the fluctuation between the downloads for the UK, Japan, and Australia. I would have guessed that one market would have been on top (and my guess would have been the UK — turns out I was wrong for 10 of the past 13 weeks). If anyone has been keeping track of international app store top 100 rankings, please send the data my way so I can make additional comparisons.
Even though I just completed a statistics & probability course, I’m not really sure what to make of these numbers, other than just to read them for how they are (to be fair to me, the course was mostly about probability and random variables, not statistics). I’m not too surprised that my numbers have declined in past 13 weeks (although they seem to be a bit on the rise now). I’m hoping that lots of people get new an iPhone or iPod touch for Christmas/Hanukkah and that will increase the installs of all of the 10,000+ applications on the App Store.
If you have any more requests for download numbers, I am fairly willing to share them, so just post a comment or @jeffrey903 me on Twitter.
Also, some potential ideas for future blog posts:
- The potential “holiday bump” (unfortunately iTunes Connect will be closed from 12/24 until 12/28, so that post will probably come closer to New Year’s or MacWorld)
- Free with Advertising vs. Paid without Advertising (or both) debate (and why I decided to only do free with advertising)
- Getting Apple to promote your app (for some reason Apple likes Currency, and I don’t have to do anything to get them to include the icon in their retail store windows, iPhone Your Life, or other website pages, but I deeply appreciate it)
- Some little iPhone development tricks (how I do the rounded corner, alternating background UITableView that Stocks also uses)
- Info about Currency 1.5 (probably coming early 2009, since I still have a little bit left to do and then Apple will be closing up shop soon until 2009 anyway)
- Anything else that gets suggested and I find interesting
