This app shuffles a deck of "cards" and allows each player to view their card by passing around the phone. This allows Spyfall to be played offline, whether it be a road trip or in a line!

More about Spyfall:

Spyfall is a easy to learn game of bluffing, quick-wits, and deception.
At the start of each round all players read their information showing the same location — a casino, a traveling circus, a pirate ship, or even a space station — except one (or more) players receives a card that says "Spy" instead of the location. Players then start asking each other questions and attempt to determine the spies before the time runs out, or when the spies guess the location correctly!
