Sparkle Stats
Some of my software (MondoMouse and Chimey) includes an automatic-update feature called SparklePlus. In addition to checking for new versions of the software, SparklePlus can optionally, if the user permits, attach some anonymous system profile information with the update check. The purpose of this information is so that I can have a clear idea of what versions of Mac OS X, etc, I need to continue supporting. I don't want to leave users stuck if I can avoid it, but I also don't want to spend time supporting old systems if none of my customers are using them anymore.
The plots below show usage trends over a 60-day period. Each day's numbers are based on a 7-day rolling average, to smooth out day-to-day variations and instead show overall trends.
