The app provides an interface for handwritten lectures and presentations. You can either project your notes while writing to a second screen, or you can pre-record your handwriting and replay it during your presentation.
Your notes can be displayed on any device that is linked to Windows 10 as a second screen, e.g. a monitor, a projector, a television, or another miracast device. You can also project to a window or screen that is shared via Skype or Zoom.
The app was written for devices of Microsoft's Surface Family, but any other laptop or tablet with a digital pen input should also work well.
