provides three organizational levels--categories, sheets, and items. By default, the app also includes three unmodifiable categories--templates, all, and unclassified.

Of course, you can add, delete, and modify any number of custom categories. You can assign a due date, priority, description, text color, URL, telephone number, mail address, and photo data to each item. Still, even with all those assignments, the only changes to an item visible in the sheet are its due date and text color. Accessing, viewing, or even knowing about the other information requires tapping the Details button next to the item.

One nifty feature to CheckSheet is its ability to copy entire items to the clipboard and then transfer them to a new item in a different sheet. You also have the ability to copy or move from one category to another. It's also possible to e-mail sheets and tag items.

Sadly, though, CheckSheet doesn't have a very intuitive interface; you're left to your own devices to figure things out. I found navigating my way through the menus to be daunting and complicated. There are no help videos, and the only gives information on what you can do, not how to do it. In addition, most every button is graphic-based, so the only way to know its function is to tap on it.

Some common buttons might help users find their way, but those features are missing in CheckSheet. There's no edit button. There's also no delete function in the menu; instead you have to go into an item or category to delete. While this isn't that big of a deal when looking at the big picture, it can slow you down.
