If you don’t have the right wine on hand, the app can also tell you where you may be able to buy some nearby, and it can suggest wines based on your tastes, budget and menu. Vivino is wrapped in an elegant and easy-to-use interface, and it’s free for iOS and Android.

To keep younger guests busy, try an entertainment app like Bounden. It guides you through dance moves and uses the sensors in the phone to detect how well you are following along.

The app is free for iOS and Android, but it hasn’t been updated in a while.
