I uploaded some apps to the Windows Phone Marketplace in January of 2011. This graph shows the daily and cumulative downloads of the apps (combined: free, trial, and paid). Despite Microsoft’s difficulties in competing with Android and Apple in the mobile phone market, at least they appear to have fairly steady adoption. At least, according to my account’s download stats. It might pale in comparison to most iOS and Android apps, but I think it’s pretty cool my creations are out there on nearly 20,000 devices.
