Appointments go on the calendar, and tasks go on the to-do list, right? But when are you going to get these tasks finished, then? You could schedule them on your calendar, but if you don’t actually do them, the calendar keeps marching on, and your task could be forgotten. SmartDay links your iCal calendar with the tasks on your Reminders list, so open space in your day is filled up with tasks you have to do. But if you don’t do them, they don’t just vanish—SmartDay keeps moving those tasks into free moments until you check them off.
