Location based reminders:

If you want to pick something up at the hardware store the next time you are there, or do something at any particular place the next time you happen to be going by that place, in Reminders, you type in what you need, and you can base it on location, and proximity within that location, so if I happen to be driving by the hardware store whether it’s this week, this month or ever again, my Reminders popped up with a reminder to go to that location and do whatever I have in the reminder when I’m within that proximity of that location! I use this all the time
