My research currently focuses on software updates on the Google Play app store.  I wrote an app to help study other apps!  It records information about when applications on your device are installed, uninstalled, or updated. Please install it to help us gather data and contribute to this research project!




The research is focused on application updates issues such as:

  • Which apps users update more quickly.
  • The rate of app update adoption through the play store.
  • Predicting the time of the next app update.
  • Security and vulnerability concerns of rapid updates. If you are interested please feel free to ask questions!


App update information is sent to F&M but it is stored under a fake name. When you install this app you will be contributing to ongoing academic research. This application is free and open source software distributed under the GPL v3.0 software license. https://github.com/fmresearchnovak/updatetimingcollector
