The Calendar app is an excellent tool for tracking appointments, meetings, and other events. By adding an alert to an event, you get a digital tap on the shoulder to remind you when and where your presence is required.

These nudges come in the form of Notification Center banners that appear on your screen at a time you specify or when your iPhone reaches a particular location. If you have an iCloud account, you can sync your reminders between your iPhone, your Mac, your iPad, and any other supported device.
