Yes, you can use Time Master Central or Dropbox. TMC is a app for your desktop computer, which you download from our site. It doesn't work on some Windows systems (for what could be many different reasons and we have not been able to determine exactly what it is), so we came up with the Dropbox method. Both are explained in the documentation, which is built-in to the app and also available for download (from the bottom of the Time Master page).
