Welcome to Typophile, Bridget.
Option B would work better in a square shape (for an app), but it seems too specific to time management, I don't see "todo list" in it.
Since the app has multiple functions, have you considered using multiple elements (maybe 4)? I know that makes the elements small which is a disadvantage, but Bento by Filemaker used a similar approach. I'm thinking simple and more iconic than Bento's more photographic approach. (Unfortunately Bento was recently discontinued, and I have most of my business records on it!)
