Heres the scoop:
You can take a picture of all your notes on the wall (or wherever) and the app scans only for sticky notes. Then, after theyre captured, you have a white background to all the stickies you just captured called a group (which is located inside a board). Now heres where it gets interesting: You can have more than one group in a board, you can add to the board (by capturing a sticky note or making a digital sticky note), and then add groups and rearrange the groups within the board. Also, you can move stickies from one group in the board to another group. Very intuitive, youre literally digitally Posting-It — thatll make sense after using it. This is one of my favorite apps. Although, I would love to see integration with Evernote & some 3D Touch support in the near future, this wont stop me from using this app.
