This app simulates a simple dash list, nothing more. All straight strokes that are drawn with the pen on the screen are counted. You can divide the screen into several separate bar lists by long strokes. Each of these lists can then be split by a long line.
The app was originally developed for the Galaxy Note 10.1 and Samsung’s S-Pen, but was also designed to work on other Samsung Android devices, with or without a pen.
Furthermore, there is now also a Windows version of the app. This uses Windows Ink and should run on all Windows 10 enabled devices.
I also made a little video about it:
