I truly, literally, honestly would not be able to keep track of my life without this app. I have seven calendars and a task list synced to my device. I'm able to color code each calendar and appointments within those calendars, plus add emojis if I need an appointment to "pop." The android widget is fantastic (mine is set as my home screen so I always see what's coming up). Cannot recommend this app more highly. I would give 50 stars if the option was available.
