Windows Phone uses tiles for the home screen. You have no doubt seen what these look like. Grouping these tiles is time consuming having to move each tile around and grouping things together. I usually group apps such as web items, social apps, shopping apps or tools. With Android or iOS you could easily make a folder to put different apps in. With Windows Phone this is not easily do able. There is a homebrew app that lets you have folders, but you need a developer unlocked phone.
This app allows you to create blank tiles to act as dividers between your tiles. It is pretty straightforward to use. You can go back and change the name of the tile if you want and you can drag it around like any other tile. The tile changes colour if you change the theme from light to dark. It gives the homescreen a nice and organised look. It’s just a shame the whole group can’t be moved around.
Here is the disclaimer from the marketplace. It seems people don’t really understand what this app does.
**PLEASE NOTE THAT THIS APPLICATION DOES NOT ACTUALLY CREATE FOLDERS ON YOUR START SCREEN.
THE NOTION OF GROUPS IS SIMULATED BY THE USE OF TILE HEADINGS FOR SECTIONS OF YOUR HOMESCREEN THAT YOU WANT TO CATEGORIES.
ANY TILES WITHIN THE GROUP ARE STILL MANAGED AND MOVED INDIVIDUALLY*
