Ever wanted to list all songs on your phone that are less than 3 minutes in duration? Now you can with Microsoft's TouchStudio. Available for free on the Marketplace, TouchStudio allows one to write variables, statements and actions that manipulate the phone with use of APIs.
There's a large array of code that's available for insertion and manipulation while the app remains user-friendly throughout use to invite non-code savvy owners to turn their ideas into executable scripts. The app provides users with access to sensors, radio, media controls, emails, contacts and more.
If anything other than useful, it's a helluva lot of fun to mess around with. As mentioned already, this app is completely free and now available on the Marketplace. Comment below on what scripts you create, including their uses of course!
