You need a fast, easy-to-use, beautiful t0-do list app. Wunderlist is that app. Sort tasks by priority and label them if you want, or just set 'em and go. Share tasks and lists (we keep a shared shopping list on ours). Your tasks sync to your other devices and to Wunderlist's browser extensions and apps. A Pro version ($5 per month) lets you assign tasks to collaborators, attach files and comment on individual items, but the free version is great too.
