If you want something that syncs to your calendar, you are in luck! It really is beautiful and such a wonderful idea. However my 3 star review comes from the fact you can't use it without syncing to your calendar, and there by having it affect your calendar. I was hoping to use this as an hourly time management tool, much like a block system, but I can't have it be that AND have my calendar be a place for just appointments. It makes the actual calendar look too full and messy. Basically in short, can you please add an offline tool as well?
