9. Never forget to do something (and never piss off your loved ones).
More awesome things to ask Siri include having her remind you to get flowers for your anniversary, or to buy a birthday present for your best friend. For some reason these simple tasks that you have to do only once a year seem to fall off your to-do list. Not any more. Thank you Siri.

10. Tips for tipping.
One of the best questions to ask Siri is how much to tip. Even if you’ve been tipping people for as long as you can remember, sometimes it’s still confusing to calculate how much you should leave for your waiter. It doesn’t matter how smart you are, after a couple glasses of wine doing math is hard. There’s where Siri comes in. She can calculate how much tip to leave and will give you options based on percentages of the bill.
