I check my app’s download statistics on Apple’s Connect app pretty frequently, and was surprised when a weekly total for my latest app was significantly less than the daily count from a few days ago. I tried restarting Apple’s app, but got the same figures.
Starting to get concerned that the figure reported a few days ago was mistakenly inflated, I checked the download statistics on the iTunes Connect site (under the Sales and Trends area), and was relieved to find the aggregate numbers there were close to what I had seen in the app for the daily numbers. The numbers in the App Analytics page are all still zero, probably because the app has only been out a week.
I have no way to verify for sure which number is correct, but the odds are that the aggregate numbers being displayed in the Connect app. In my case, the numbers were over 10x smaller than they should be, which is a pretty serious bug.
If this doesn’t correct itself, I may send Apple a note since it’s pretty bad a bug this basic could escape unfound by testing. But maybe it only happens in a rare situation that doesn’t effect most users. Though the numbers are slightly different for my apps that have been out for several months, the difference is no more than 10 downloads.
If a company like Apple can’t provide accurate download statistics, it might be wise to consider using some 3rd-party SDK like Flurry which should give a more accurate count, plus much more information on how your app was used. I haven’t tried this myself, but am considering it eventually.
If anyone has noticed this bug please let me know.
